TT:The concept of having the coax and other lines leave the tower ABOVE earth
level, is alien to me. I've always felt that the capacitance of the coax
bundle to earth would tend to limit a strike's current in the direction of the
shack, in favor of the lower impedance tower connection.HOWEVER, you COULD
have the coax leave the tower at 10' or so, making a solid connection to the
tower at that level, and letting the tower be the conductor to the earth ground
system. The problem with flying the cable bundle, however, would seem to be
twofold. 1) reduced capacitance to earth, due to increased distance, and
therefore reduced strike current along the bundle; and 2) having the flown
cables act as a larger loop, in the event of a nearby strike. In the latter
case, there would be greater current induced in the secondary turn of the 1
turn transformer represented by the tower-cable system. Does anyone see a flaw
in that thinking?N2EA
