[Antennaware] Force 12 Sigma-5

[Warren Rothberg]

OK, I'm a newbie to the group. I did search the archives first, tho.

I am CC&R'ed to death here in my gated condo community with no outside
ground I can call my own (EVERYTHING outside my walls is common element).

My directors have agreed to let me have a "small" antenna as long as it
is not a "permanent fixture". Thus I now have a Hustler Mag-mount on my
roof air conditioner. This has been SO effective, I have been off the
air for more than 2 years. (I watch the DX Clusters with such envy!)

Both Force 12 and the QST review of the Sigma 5 recommend operation at
ground level for optimum effectiveness. My only choice is a corner of my
roof at 15 feet AGL. At that point it would be 10 feet away from my A/C
unit.

So here's the question: Does anyone have experience with this antenna
at 10 to 20 feet off the ground and can you compare it with ground
operation?

Thanks,

Warren, W4WR
