Author Topic: Insatalling sat antennas on top of an HF beam?  (Read 685 times)

Forgive me if this seems a little of topic but I couldn't find a better place to ask. I'd like to separate my azimuth and elevation rotators and place a small HF beam on the azimuth rotator with the elevation rotator and 2M/70CM sat antennas installed above it. Aside from the obvious amount of clearance needed to keep the sat antennas from hitting the HF beam during elevation changes what is the rule of thumb for determining the distance between the two arrays to minimize interaction between them?
Tnx and 73,

Hi Michael,
6´(six feet) and depending on the sat array, if it is a small array say crossed 10x10 no problem. Should the array be larger then the array should be placed at 90 degrees to the HF system to avoid ¨locking the satellite antennas into the HF antenna. However, if you can get the system up to 10 ´then it will not be a problem.
The only issue is accessing for maintenance.
