Tom, N6BT (founder of Force 12) has been known to say, "Everything will
radiate." He often shows pictures of his "Illuminator" antennas to
prove it. One is a light bulb on a post fed with coax and a current
balun at the socket. He's actually worked a surprising amount of DX on
it. He also has the "Phased Illuminator," three bulbs in a Vee
arrangement with the power divided between them.
My main antenna for the low bands is a non-resonant inverted vee about
70' at the apex, about 155ft on each leg, with the legs ending just a
bit over head height, and a central angle of about 120 deg. It opens to
the east. I adjusted the leg lengths to give tractable impedances at
the feed point on 30 - 160, and a section of 450 ohm ladder line (length
calculated using N6BV's TLW that comes with the ARRL Antenna Book 20th
ed) feeding a 4:1 DX Engineering balun near the bottom of the tower w/
coax to the house. It is pretty much omnidirectional on 40 and below,
and a cloud warmer on 80 and 160. The pattern gets pretty goofy above 30m.
My guess is that your arrangement may exhibit similar characteristics,
but then, antennas can be magic. Stick it into EZNEC and see?
