RE: [WISPA] Lightning hits
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 am not worried about lightning strikes because I cannot stop that. Mostly the part where stuff catches on fire. The problem seems to lie in the fact that I have an 11ft tall omni that is the second tallest thing on the tower and it sucks in static like a vaccum and takes out the RF side. So would powering off save the RF until I figure out what can be done with the tower (grain leg) Brian Chad Halsted wrote: I'm not 100% sure, but my first inclination would be no.

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.
