Another very simple approach involves two Inverted-V's perpendicular to
each other, one with 67 foot legs on each side and the other with 63
foot legs (common apex at 70 feet high). It looks pretty decent in
EZNEC+ from 3.5 MHz to just over 3.8 MHz and I plan to try it out in a
month or two when I finish some other projects. It even has a slight
bit of directivity. I can send the EZNEC+ file to anyone who wants to
see it.
If anyone has tried something like this and it didn't work very well,
I'd like to know. ;) I live on a steeply sloping hillside so my
takeoff angle toward Europe and Africa from here in southern Arizona is
much lower than would normally be expected for a height of 70 feet. See

I never understood why the AI1H 75M/80M vee has not gotten more
traction. I've built two; they're not very difficult to make, and
they've withstood hurricanes and tropical storms quite well.
