Re: Apartment Dwellers



Margaret,

I get a workable downlink on RS12/13 from a _basement_ apartment. I have a
wire 10m dipole at two feet agl (just above my window) for RX and a 2m half
wave mobile vertical which I have managed to get on the roof at 100'.
Although I have to run about 100-200W in the shack to get an SSB downlink
(there's about 6db loss in the coax to the roof).
