Hi Gordon,

Satellite antennas don't need to be high, just high enough to see the sky. If you don't have any large obstructions (neighbor houses, dense trees) nearby, I'd opt for a little safety over absolute altitude, and keep the antennas separated. Go for the shorter coax, if that tips the scale one way or the other.

My own setup has an HF dipole about 10' from my rotor and beams for 2m, 70cm, 23cm, and 13cm (receive only). I run 100w on HF, and have had no problems with the VHF/UHF/etc. equipment that I've detected. Of course, everything gets into the phone and stereo system, but that's a different problem...

I'm beginning the construction of the 2 Meter and 70 cm EZ-Lindy antennas to get myself launched into working satellites. I'd like to mount them 3' to 5' above my HF Hex-beam in order to get them as high as possible (other mounting options such as a tripod & short mast on top of my garage do not get the Lindy's as high). I will mount the ICom 2 Meter & 70 cm pre-amps on the Lindy's as well. Does anyone see that exposing the pre-amps (or my new 910H) with as much 300-400 watts of near-field HF would be detrimental? Normally I would not operate HF and SAT at the same time however the 910H might be turned on and in receive mode during HF transmissions. Any thoughts about the wisdom (or not) of this proposed Lindy mounting?
