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

transiting through the device the radio waves bounce back from the device. This
could damage your transmitter, will reduce your transmitted power, and increase

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
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.

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.

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,
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
