Hi,
Does anyone know where I can find the PoE lightning protector for MT router
board 411?

We had all sorts of lightning issues at our primary tower 15 years

What we did was put a ground ring around the tower, and another ring
around the building connected to that ring. 150 ground rods

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?

I've not tried Vyatta either, but I've done PFSense and got tired of waiting

RouterOS seems much more powerful and configurable to me. Though maybe you can

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

I have some Altelicon glass tube lightning surge arresters. I am trying

old and new.
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
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.

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.
