Hi all,

I'm considering putting up a 33' vertical - just 3 sections of Rat Shack
mast (solidly bolted for continuity) plus a 3+/- foot 'adjustable' part
on the bottom to 'trim' the length. Then a bunch of in-ground radials.
40m is my only 'serious' band. 15 meters should be a bonus, right?
Or not?

Would this work better than my 4BTV (which I'll keep for 20 and 10)?
Or would the improvement be so insignificant as to not be worth all
the bother of building the new antenna?

Thanks

Should be fine on 40M. Although the match might be decent on 15M, the
high
takeoff angle will not be good for 15M DX.

I use a Fluidmotion BiggIR vertical on a 3500 ft^2 aluminum roof. The house
is on a hill in the country.
Works great on 40. I really like it. The DX at 3AM (that is just not there
on a dipole) is LOUD.
I can use it as a 3/4 or 1/4 on 15 and can't tell much difference.
Sometimes one is better, sometimes the other. Propagation can be complex.
Nice to be able to push a button and see which is best.
