I did some rearranging today...
The '940 which I used to talk with a number of Islanders on 75M has now been connected to an 80-40-20-15M inverted Vee at the western edge of my yard, and the G5RV that was attached to the '940 is connected to an Astro 103/1500ZA/ST-2B combo. I now can run QRO on 75, 40 and 20 without worrying about near-field RF exposure issues involving the neighbors.
Still giving some thought to pulling the 'RV down and replacing it with a loaded/fan dipole (clone of an A-D 80/40 unit with 20M added) or perhaps rolling my own.
On-the-air tests will be the proof in the pudding, so to say.
May be on later tonight if anyone is game.
