Gentlemen: If you were going to put up monoband antennas for 10, 15, and 20 on separate towers and they were going to be used primarily for domestic contesting, what heights would you put them at? An
I would put them at 1 wave length each. Good high angle take off as well as a good lower lobe. (30 and 60 degrees if I remember right) Peter VE6YC _______________________________________________ See
Five minutes with the program YT (comes with the arrl antenna book), using arrival angle statistics for Iowa to USA, produces the following results, assuming flat terrain: 10m - 45' 15m - 55' 20m - 7
If i remember these were all going on seperate towers... you could always use stacks .... that way you can move the angles all around depending on condx... especially on 10 ..... good luck Dan N8DCJ
Quads are comfortable at just about any height. You'd like to have them above nearby obstructions if possible but that's about all. Yagi's on the other hand like to be from .7 to 1.2 wavelengths abov
I have 4 element W2PV design monobanders stacked on my 72 foot crankup. And I have a Force 12 C3 on a 37 foot tubular crankup. During domestic contests I find the C3 outperforms the monobanders from

I won the ARRL SS three times with a tri-bander at 48 feet and wires. Once I got my 72 foot tower I found that hams at 40 to 50 feet would beat me out to Central America. That is why multi ops have s
