I would aggree with the comments made by Charles. I too, use an inverted
vee with 44 foot legs and an apex ht. of 60 feet. It works (and models
on the computor) very well on 80 thru 30 m. It loads up fine 20 thru 2
meters but the radiated pattern is less than desirable for those bands
when compared to an equivalent half wave dipole of the same type or even
a quarter wave vertical on the roof. The inverted vee pattern for these
bands is very different compared to the flat top (horizantal) pattern.
This is discussed in some detail in the current ARRL handbook and in the
4th Antenna Compendium.
Don't get me wrong, the antenna will work and you will make lots of
contacts, but you will work more dx on the high bands if you can get the
antenna horizantal or but up a separate (shorter) dipole or inverted vee
(eg 25 to 35 total length.)
