Central Florida experiences "16 and up" strikes/sq-km/year. < http://www.weather.gov/os/lightning/images/map.pdf > Experience bears this out... I live on 6 heavily wooded acres and have had at least 6 trees struck and killed somewhere on my property over the last several years. I make it a faithful practice to disconnect antennas from any gear during the frequent thunderstorms we experience. I have considered fastening a GPS antenna on the end of a 12 foot fiberglass pole and installing it in the top of one of the trees next to my workshop building so that it has a clear 360 deg sky view down to within a few degrees of the horizon. It would be nice to come up with some way to use fiber optics to isolate the GPS antenna from the receiver. Coming up with a solar panel and battery to isolate the antenna and RF preamp power is no big deal but coming up with a way to isolate the RF via fiber is more problematic. Any thoughts/comments on this...? Thanks!!
