After putting most of my radios on consignment - and eventually selling them - I was able to purchase a Kenwood TS-590SG to be used as my "base" HF unit. I also purchased a Kenwood TS-480SAT, Comet SAA-500 Mark II antenna analyzer, Hustler MO-3 (54") and MO-4 (22") mobile whips, 400 watt resonators for 80-10 meters, a VP-1 tri-band adapter, and a D-322 mount.
My first attempt at a usable antenna in my apartment was the Hustler antenna on the D-322 mount on a modified Sony VCT-R640 tripod (modified = I removed the camera mount) with a counterpoise. Failure.
Second attempt was to ground the antenna base. I was able to match the antenna. Noise. When I used the MO-3 without a resonator for 6 meters at 5 watts, the mic went hot. RF burn. Fail.
Third attempt was to ground the TS-590SG. Because the ground is attached to building steel, I was in a Faraday cage, effectively nulling my signal. Fail.
Fourth attempt was to purchase a Chameleon F-Loop antenna with the 80 meter add on. Success, save for the standard RFI in an urban area (bzzzt....bzzzt...bzzzt). I'll review the F-Loop later with instructions to make it work with the Kenwoods (or any modern HF transceiver with an internal tuner).
The TS-480SAT will be used for my mobile and field work. I'm looking forward to experimenting with the verticals and the F-Loop outside. I've also ordered HF verticals from GAM (WeatherFax/DSC) and Metz (General Coverage).
Of course I'll post the results.
