[Antennas] INVERTED V

Stan,
The inverted vee still lives, especially due to its need of only one tall
support and two lesser ones. Inverted vees tend to have a more
omindirectional pattern but still some dead spots in radiation pattern. The
sharply angled vees are poor in comparison to a dipole at the same height
but an inverted vee is by definition not at the same height. My suggestion
is if you want to or have to use a vee try to get it up as high as possible
and make the angle as shallow as possible. I have two vees, one 80 meter
length, center height at 40' and ends at 15', and fed with 300 ohm twin lead
and using my new homebrew balanced twin roller inductor tuner. Angle of vee
is about 140 degrees. EZNEC says the antenna shoots straight up in the air
on 80 through 20, has a low angle of radiation of 15, 19 degrees, and
exhibits long wire tendencies on 10 meters, shooting off the ends. I have
found these to be true by experience. Incidentally first test of new tuner
on 15 meter SSB was to Siberia. Second vee is off-center fed, 69',
especially engineered for 20 meters low angle DX from a low height, 25', and
it beats the higher and longer antenna on 20 meters. It's a matter of using
what you have. Hope this is of interest.
