Gas tubes for 5, 6 and 11 GHz? I bet the microwave down-coverts at the back of the dish and your running 1/2 LDF down the tower. I've never seen a lightning surge suppressor on a piece of waveguide a

It runs IF and DC up an LMR600 run between the transmitter in the shack and the amplifier up top. The amp takes N-Type from the IF and has Waveguide out to the antenna(s). The 6 and 11Ghz stuff is al

most of the time, the loss is at higher frequencies, and is a worst case guarantee. _______________________________________________ _______________________________________________ TowerTalk mailing l
