My feed got hit by lightening, indirectly, last week. Looks like it smoked the Cat5 or the eth1 port, but the radio works fine, just no connection to the ground.
I took a Crossroads and set it as a bridge to an unused AP on that RB, and I'm currently feeding my entire system with a wireless hop from the ground to the tower, tower to my tower. Crossroads is moving 1.5Mbps in WDS, CPU is around 30%.
If its just a point to point bridge, I don't see the problem. I'm thinking of keeping this sort of config, probably change to 5GHz, as I have no liability now. If lightening hits my equipment on the tower, it can't fry the landowner's.
edit: one thing worth noting. Same antenna, same cable, same pigtail, Crossroads shows 5dB better rx signal than the R52H.
