    OK, I boxed myself in with a QRP transmitter-Directional Beam Antenna?

    I got my TenTec Argonaut, but 20 Watts SSB ain't gettin' me far. I am going to try digital but I would like to keep SSB and AM viable. The linear RF amp is way in the future so right now I'm looking at the antenna. I (read that wife) doesn't want a tower and yagi in the yard, so I'm stuck with wires in the trees. So I was thinking Vee Beam dipole? I was thinking about a Horizontal Vee Beam. Is it feasible to run two dipoles one N-S and one E-W in a cross shape and connected by insulators in the middle. What I want to do is have 4 legs each about 70 foot long and fed in the middle by two 450 ohm ladder feed lines. Then by picking any two wires from the feed lines, I can have a choice of feeding a N-S 140 ft dipole, an E-W 140 foot dipole or a choice of 1 of 4 seventy foot, 90 degree horizontal vee beams with main lobes going Northeast,Southeast,Southwest, and Northwest and hopefully at least a 3db gain in those directions.
