Re: [WISPA] Lightning AGAIN
We had all sorts of lightning issues at our primary tower 15 years ago. Here's what fixed it: What we did was put a ground ring around the tower, and another ring around the building connected to that ring. 150 ground rods interconnected with #2 solid copper cad welded to the rods. Each leg of the tower is cadwelded with #2 sold and that is cadwelded to the tower ring. From that ring, we bring in #2 awg 'stingers', or connections into the building that the equipment gets grounded to. Rack, Routers, everything. Avoid ground loops. I would also recommend lightning dissapators that discharge the ion field before the strike ever happens. A ground rod with it's own #2 from the top of the tower should also get connected to the ring. Shielded ethernet cables everywhere since the emf from the lightning couples into the high impedance line and fries ports. APC UPS's on all AC, TrippLite IsoBar surge protectors or TrippLite PDUs on all AC connections. All radio cables coming from outside are shielded and grounded. All those go to grounded surge protectors. All RF cables have grounded polyphaser surge protectors (these rock). Knock on wood, not an issue since then (10+ years).

Re: [WISPA] Lightning AGAIN
Are the APC's grounded and do they have the industrial strength surge protection necessary to divert a large inrush without too much voltage rise?

Re: [WISPA] Lightning AGAIN
I've not tried Vyatta either, but I've done PFSense and got tired of waiting for features that weren't quite working in beta. RouterOS seems much more powerful and configurable to me. Though maybe you can do as much with PFSense at the CLI.

Re: [WISPA] Lightning arrestors
You have to check the specs. The possible problems are high VSWR. Rather than transiting through the device the radio waves bounce back from the device. This could damage your transmitter, will reduce your transmitted power, and increase receive loss (reduced receive signal strength). It's also possible for the device to maintain a low VSWR (still present a 50 ohm impedance at 5.8GHz) but be very lossy (reduced transmit power, reduced receive signal strength). I don't believe the lightning protection benefits are any different between units for different bands. The difference is how it passes the RF signals you're trying to pass through it (loss and VSWR).

Re: [WISPA] Lightning arrestors
They are rflinx quarterwave rated from 2.1-2.7, they were used instead of polyphasers on a couple of new backhauls we deployed. I'm seeing unusual noise floors on both of them which I know are incorrect due to the readings from previous 5.8 gear that was replaced. I'm just wondering if this would be a symptom, what does the frequency range actually mean on those I suspect it would make my noise floors go out of whack like that. They aren't in use and I will replace them before going into production, I'm just curious. Regards Michael Baird I second that. Most ARE rated for up to 5.8 but don't seem to list it unless you ask.

Re: [WISPA] Lightning protection
A combination of surge protection and proper grounding is the key. We utilize a multi-point ground tester and find a large portion of our sites have poor grounds (less then 5 Ohms to earth) or some crack head stole the buss bars and copper. (Very likely in FLA). Testing has become part of our semi-annual maintenance. We also utilize static dissipaters to reduce the conditions for lightning to form around the site as well as surge protectors. As far as Transtectors, The large one for the canopy is very well designed and works well. We have replaced all of the ALPU-ORT (PTP Transtector versions) with the new Motorola units. They stand up better, are made for hanging on towers and don't fill with water after baking in the sun for a few years.

Re: [WISPA] Lightning Surge Suppressers
Mark, I doubt the ohmeter will tell you anything. The gas tube is supposed to measure open. It's job is to conduct only when lightning needs to be shorted to ground instead of going through your equipment. Put the arrestor inline between an antenna and a radio. If the radio works as well after installation as it did before then the arrestor is probably OK, assuming the gas tube isn't bad. After a lightning storm, if your radio stills works as well as it did before the storm then you know the gas tube is probably good. If you think the gas tube is probably bad then just replace it with a new one. jack Mark McElvy wrote: I have some Altelicon glass tube lightning surge arresters.

Re: [WISPA] Lightning Surge Suppressers
The way I test the surge suppressors I manufacture is to place a high voltage across the suppression device (such as your gas tube). The voltage must be higher than the breakdown voltage of the device. Frequently 120 VAC from the outlet will do. I use a variac coupled to a step up transformer so I can go to 1000 volts if needs be. You must put a current limiting resistor in series with the gas tube to keep from blowing a circuit breaker and damaging the gas tube. If the gas tube is firing, it will have a voltage across it at whatever level the breakdown voltage is. If it is not firing, the full applied voltage will be measured. If it is shorted, very low or no voltage will be seen. - Original Message - From: Mark McElvy [EMAIL PROTECTED] To: WISPA General List wireless@wispa.org Sent: Tuesday, May 20, 2008 1:15 PM Subject: [WISPA] Lightning Surge Suppressers I have some Altelicon glass tube lightning surge arresters.

Re: [WISPA] lightning rods?
I made one out of an old (shot) bearing that came with my tower (I got it free for taking it down) and a few pieces of stranded heavier gauge copper wire. The bearing was for a mast I don't use, so I was able to mount it on the very top of my tower since it already had the mount for it there. It's only grounded to the tower metal itself and has been up for a little over a year. I haven't blown a radio on that tower yet, so I presume it's doing the job... we've had plenty of lightning storms come through this year.

Re: [WISPA] Lightning Protection
Jim, I too have the pleasure of enjoying the wonderful Kansas Storms... Our main tower had been hit three times (in a row, in one season) while i have been using it for wireless, and I got fed up with changing out the equipment each time. I have found that on most of the towers, if it has a good ground, and you leave some of the tower, or a pole up higher than your equipment, there are no Lightning problems. On our main tower however, it was not grounded well. So in doing a little research I came across this kit from glen martin (I am sure there are others out there too) http://www.glenmartin.com/catalog/lightning.htm It came with everything but the wire to run down the side of the tower, which i was able to purchase from our local electric dept. I installed it, as well as drove a rod at each leg (it was a self supporting tower with three legs) and grounded each as well. since this was installed, I have not had a single problem through two seasons of storms now. I also installed a surge protection system , in my equipment room, that is connected to a ground bar that is tied to the tower as well. (an electrician told me to make sure your have your grounds tied together. Something about ground differentials, or equipment from two different grounding sources. I cannot remember the exact reason) In the past it seemed I was losing the equipment (or more specifically the mini-pci cards) from at least one tower everytime it decided to cloud over, due to another problem as well. Come to find out most of that problem was related to static build up on the antennas. (in fact every Omni directional antenna i had nearly, popped a card each time it clouded over) I found a solution to that as well, which you can read about here ( http://forum.mikrotik.com/viewtopic.php?f=7t=9734hilit= Topic:Wireless card recieve blows issue, in Wireless Networking Category ) on the Mikrotik Forums.

I cannot remember the exact reason) In the past it seemed I was losing the equipment (or more specifically the mini-pci cards) from at least one tower everytime it decided to cloud over, due to another problem as well. Come to find out most of that problem was related to static build up on the antennas. (in fact every Omni directional antenna i had nearly, popped a card each time it clouded over) I found a solution to that as well, which you can read about here ( http://forum.mikrotik.com/viewtopic.php?f=7t=9734hilit= Topic:Wireless card recieve blows issue, in Wireless Networking Category ) on the Mikrotik Forums. Again Since implementing it, Havent lost a single card. Hope this all helps. Jaron Parsons Sumner Communications Jim Stout wrote: Spring arrived in Kansas City and so did the thunder storms. I took a lightning stike on my tower and lost both APs, the POEs, two switches and a Mikrotik router. The Antennas survived but it looks like I lost a little gain. My question is how do I protect against this happening again? Are lightning rods effective? Any thoughts will be appreciated. I don't want to have to replace everything again.

Re: [WISPA] lightning
DigiKey lists a standard inductance for each core and the frequencies they filter. Its been awhile since I researched them, but my primary focus was the FM interference and my secondary was just to get as much inductance as possible for lightning suppression. - the more times you loop the cable through it, the greater the inductance. I go for as many loops as I can possibly get. A lot of times, I buy the inductor mostlybased an the physical size that will work for my application. I use them on just about everything, even my RF pig-tails (with no looping). Brad Hagstrom On 10/17/06, Dylan Oliver [EMAIL PROTECTED] wrote: How do you compute the total amount of inductance?

Re: [WISPA] lightning
I use ferrite beads for the same reason. Sometimes I use 2; one at the radio and one right before the cables enter the house. DO NOT put them on a ground wire since that's where you want the lightning's current to go. Because its current has such a fast rise and fall time, lightning behaves like ac or rf. That's why ground wires are supposed to be as straight as possible, and if you have to bend it, you should make the radius of the bend as large as you can. A tight bend acts as a coil (increased impedance) and will cause the lightning to look for a better path. Ferrite beads do the same thing. By putting a ferrite on the cables, you still let your signals through, but it looks less inviting for the lightning.

RE: [WISPA] lightning
I have a friend that is a tech for VZ and goes around replacing cell gear hit by lightning. Even with the protection that VZ puts on their equipment, grounding, surge arrestors, etc., let's just say he gets a lot of overtime during the summer. ;-) No matter what you do to try to protect the gear, you will still see some failures. Of course, those failures can be reduced by adding surge protection. I think you have to look at the numbers to see if they work for you. If you can estimate your failure rate and the cost each failure costs, then you can compare with the $30~50 more you will spend to try to protect it. Also, you can compare the cost to the cost of a radio that has built-in surge protection (usually a few $$ more to pay for the protection device). If the numbers work out, then add the protection. If it does not, then don't. Of course there is also the health aspect I suppose... ;-) -Hal __ Harold Bledsoe Deliberant LLC 800.742.9865 x205 http://www.deliberant.com -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of KyWiFi LLC Sent: Saturday, October 07, 2006 3:53 AM To: WISPA General List Subject: Re: [WISPA] lightning Lightning is by far the largest threat to our WISP.

Contrary to popular belief, lightning likes to follow the path of least inductance. Inductance is the resistance to a change in current flow. All I can say is that they have worked for me.

I'm not 100% sure, but my first inclination would be no. If lightning hits your tower and the equipment/tower is not properly grounded with surge suppression in place, it will get blown, whether it is powered up or not. Current is still going to flow through the radio; it just won't make it out the Ethernet because you unplugged the line.

RE: [WISPA] Lightning hits
I really don't think it's going to make a difference. If it's pulling in that much energy through the antenna, it's got to go somewhere, and the only place it can go is through your pigtail strait to the radio. If the radio isn't properly grounded to the tower, and the tower properly grounded to well, the ground, something is going to get smoked. I don't THINK it's going to matter much if the power is on or not. But hey, it's worth a shot. It sure won't hurt to try. One of our 50' towers has a big ham yagi antenna on the top of it. The home owner said that his yagi was pulling in so much static he could hear it arcing from across the room. It was arcing from the connector on the end of the cable to a nail that was driven into a 2X4 stud. There wasn't a cloud in the sky at that time either. That's some crazy stuff.

Re: [WISPA] Lightning hits
Hey Brian, You should have a lightning arrestor between the antenna and radio, well grounded to the tower, also an arrestor between the radio and your red barn, well grounded. That should protect the radio as well as can be. 7/1/05, my tower was hit, I had all the arrestors in place, and well grounded. Of the 4 AP's on the tower one survived, but I have had good luck since.Ron Wallace Hahnron, Inc. 220 S. Jackson Dt.

RE: [WISPA] Lightning Protection
So does this mean that cabling and equipment should be grounded to same source? I understand grounding the cable prior to entry. Does grounding my cable to one ground and then using the shelter power, which is on a different ground, set up a potential on the equipment? Maybe disconnect the ground on the power side and bond everything to a single point? Chris Your sapose to do both ground outside before you get to the shelter portand insideto tie into the ground ring inside the shelter. -- WISPA Wireless List: wireless@wispa.org Subscribe/Unsubscribe: http://lists.wispa.org/mailman/listinfo/wireless Archives: http://lists.wispa.org/pipermail/wireless/
Re: [WISPA] Lightning Protection
Your sapose to do both ground outside before you get to the shelter portand insideto tie into the ground ring inside the shelter. Your grounding should be every 75 to 100 feet of your cable run down the tower.So if you have 300 feet of cable run your going to have 3 grounds in your system TOP, MIDDLE, BOTTOM. I usually see at least two TOP and BOTTOM, one at the ODU and one inside or sometimes outside if the grounding bar/ring is on the outside of the tower.Nothing really wrong with just two, butone every 75-100 feetis standard. It can be different from tower to tower depending onhow the site was engineered and built. Example most ALtel sites have a ground bar at the port entery ( outside) to the shelter which ties into the main ground ring, on this site yes you would ground outside. You still have to ground the equipment to the rack inside the shelter, but your surge supressor would go outside. Other sites you will have to ground inside because the site designhas the bus bar ( ground bar ) inside just after the entery port. Both designs are very common. So to answer yes it does good to have a supressor inside its you last defence untill you get to the radio ( idu ) and then as long as its grounded to the rack and the rack is grounded to the ground ring inside the shelter it should be a well protected link but even then it isnt a garrenty that you are 100% safe. Lightning is a strange hazzarded to try to ward off. I am in Florida so I see just about everything as far as protect ion goes. And I can tell you right now that if your customer isnt a MAJOR carrier you site is probably not properly designed aganst lightning strikes so you need to bring them up to speed and properly ground the site or the customer is just asking for trouble.I work with a local WISP that had no Idea about grounding and I have had to redesign the ground rings on most of their sites. SO FYI it doesnt matter how much protection you put in if it isnt properlydesign inside and shelter and outyour equipment will get fried everytime.

Re: [WISPA] Lightning Protection
The only reason I asked this and think it's funny - *no offense intended* is b/c one of my techs did an install like this - Apparently when the tower got struck by lightning - the enclosure exploded due to the discharge ring on the supressor inside of the box... I mean literally exploded. I had routerboard / enclosure crap for 100s of ft all around the tower. Wish I could have gotten that on video.

What is FiberCor, and where do you get it? Would you post a pic of one of these assemblies? Thanks,-- Dylan OliverPrimaverity, LLC -- WISPA Wireless List: wireless@wispa.org Subscribe/Unsubscribe: http://lists.wispa.org/mailman/listinfo/wireless Archives: http://lists.wispa.org/pipermail/wireless/
