My latest plans include a 30' telescoping TV mast that will be guyed with
non-conductive lines. It will be centrally located on the lot (just behind the
house). With it, I should be able to run a 66 or 88 ft doublet fed with 300 Ohm
TV twinlead. At 30' up, it should be up high enough to keep the antenna pretty
efficient (compared to ground losses at 10' and below). It won't be much of a
DX antenna except maybe on 15-10m. On 80/40/30m, I pretty much want NVIS
capability for local and regional nets.

I appreciate the ideas, and am glad to see that they run along the same lines
that I've come up with.

72/73!
