I've used these guys for grounding the shield of a cat5 cable:

Eric Rogers wrote:
I was just referring to the shielding by bonding it to the cat5 crimp on 
ends, not soldiering them to the tower or grounding materials.  There is 
only a friction bond between the cat5 end and the grounded casing of the 
surge arrestor.  I would think the friction bond would have more 
resistance in a strike, causing it to heat up faster than the resistance 
of the soldier.


 

Again, with millions of volts, I don’t think the Cat5 cable would hold 
it as well.  The key to the whole system is the grounding to the tower 
site itself.  In this case, there are 3 runs of 5/8” or larger copper 
running from the grounding grid to the very top of the tower and 2 cad 
welded to the tower base and the grounding grid.  Hopefully the 
lightning will choose the path of the copper or tower, and not my run of 
cat5.  The shielding and soldier is only to dissipate static buildup and 
keep the potential voltages as close to equal as I can.


 

My thoughts are that if the antenna’s and equipment at the top are 
grounded to the tower, the equipment at the bottom, and all the surge 
suppression for the cat5 and coax runs are all grounded to the same 
ground plane, the potential voltage difference between any one location 
should be near 0, and there should be no need for it to travel up/down 
my cat5 run.


 

Hopefully it will never need to go through my soldier joint or the 
pressure of the spring steel in the surge suppression.  :)

I believe that solder is probably not a good idea here.  Lightning can 
build enough heat to melt the solder and thus break the connection.  I 
think all ground connections need to be physical connections to provide 
the best protection.


Otherwise, this looks like a good method.

There are several devices designed to give mechanical and electrical 
connection to shields, etc.

 I myself use them at our tower sites at the bottom AND the top.  I had a
 tower get struck, directly and lost everything...including the switch at
 the location.  Since then, I figured 3mil volts can go through thin
 cat5e jacketing.  Even through the shielding if it isn't properly
 grounded.  Now I soldier the casings onto the crimp on ends when
 possible so hopefully it will go to ground without hitting the copper
 inside.  I use the Hyperlink surge protection, and the keystone jacks
 are for shielded cabling, so it goes to ground.  The surge suppression
 is just added protection.  Remember, electricity takes the least path of
 resistance, when metal heats up, it becomes more resistant.  So that
 bolt of lightning can go where it wants...

 That said, I am giving the electricity 2 points to exit to ground, so
 hopefully I don't lose any more equipment.

 The tower is WELL grounded, it is an old AT&T sight, with the copper
 mesh in the ground, and all buildings and towers have copper 5/8" or
 larger going up the sides and cad welded to them and also to the grid
 below ground.  LOTS of money...

 I don't at the CPE, just use the built-in surge suppression and
 definitely ground the CPE for static.  I see it as if the house gets
 struck by lightning; they have more to worry about than internet... Now
 if a tower gets struck, I have hundreds down, not 1.

Connectors I use 010-108 from www.cablesforless.com
https://www.cablesforless.com/index.asp?PageAction=VIEWPROD&ProdID=794.


I buy a lot of patch cables and things from them because they are fairly
cheap and they are local (2 miles away).  I try and promote local
business when I can.

I get the cable from www.cat5ecableguy.com.  Two different part
numbers... http://www.cat5cableguy.com/inc/sdetail/12771 or
http://www.cat5cableguy.com/inc/sdetail/12770.

RE: [WISPA] Self Adhesive Mini PCB supports for Mikrotik

2006-08-27 Thread Eric Rogers 
I myself use them at our tower sites at the bottom AND the top.  I had a
tower get struck, directly and lost everything...including the switch at
the location.  Since then, I figured 3mil volts can go through thin
cat5e jacketing.  Even through the shielding if it isn't properly
grounded.  Now I soldier the casings onto the crimp on ends when
possible so hopefully it will go to ground without hitting the copper
inside.  I use the Hyperlink surge protection, and the keystone jacks
are for shielded cabling, so it goes to ground.  The surge suppression
is just added protection.  Remember, electricity takes the least path of
resistance, when metal heats up, it becomes more resistant.  So that
bolt of lightning can go where it wants...

That said, I am giving the electricity 2 points to exit to ground, so
hopefully I don't lose any more equipment.

The tower is WELL grounded, it is an old AT&T sight, with the copper
mesh in the ground, and all buildings and towers have copper 5/8" or
larger going up the sides and cad welded to them and also to the grid
below ground.  LOTS of money... 

I don't at the CPE, just use the built-in surge suppression and
definitely ground the CPE for static.  I see it as if the house gets
struck by lightning; they have more to worry about than internet... Now
if a tower gets struck, I have hundreds down, not 1.

Do you find that a surge supressor at the CPE is better then at the 
internal PC/Router/Switch? Or do
you use one at each end?

Looks good. What radio are you using with what looks to be a Realtek 
SoC? Is that

a PoE splitter, a surge supressor, or both? How long is that RF pigtail?

They have them in stock now.  I remember there was some talk about
 


these
 


a while ago.
$50 min order so I just got 400 or so of the self adhesive PCB
 


supports.
 

I got the 5/8 standoff (should be able to fit the cards under the 
board too)


I don't need 400, so if anyone wants a few, let me know.

Otherwise, just letting ya'll know they are in stock.
