anybody on here run a high power (3kw+) suburban? i need some advice

[whiteastro]

no on the 75ohm coax, thats used for a co-phase set up with two antennas.

as for the back reflector antenna, it needs to be about 6" taller than the front...and 72" spacing between the two .
you may have to play with the height of the back antenna some, but the set up should tune lower...

are you using a antenna analyzer on this?

Thanks JJD I have to laugh because I still have a lot to learn on this stuff!
