What have you guys found most cost effective (and it needs to work) for
lightning protection where the cable enters an exterior wall?
How much and where do you get them? So far the motorola units seem to be
the best I've seen for what you get and how they work...
I'd like to inquiry this mailing list on what other WISPs use as far as
lightning protection. We've had a bad spring every other year with
something going bad. This recent past spring two towers were hit causing
massive outages and a really bad day.
We have a stock of these things which is why
We are mostly Canopy and Redline AN80 around here. We have had great luck
with the transtector ALPU-POE for Canopy and have had great luck with the
units that are recommended by redline for AN80. We're actually trying on a

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
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
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,
Does is really do any good to have the supressor inside of the enclosure grounded to everything inside ? I thought the suppressor was supposed to go straight to ground ?
