Good enough for WHAT?
When the sunspots return, a two element mini-beam at 30 ft on 20 through 10
meters will make you smile compared to a dipole or vertical. A SteppIR
DB-36 or a 40 meter two element and a FORCE-12 5BA at 100' will glue that
smile on your face. Or do you want to dominate in contests?

Subject: Re: [TowerTalk] 'WWV halfwave vertical", was Vertical vs Beam
Exactly my sentiments on these two points (see quote below)
1) GAP has at least one antenna which employs three 25 foot
"counterpoise" wires that are not connected to either side of the coax
feeder... and is supposed to be of some help. I talked to their sales guy
at Dayton last year and walked away unconvinced and bought another antenna.
2) I understand and agree with your high and low band choice ...
Which leads me to this question:
Now.... on a small suburban lot... how small a beam, and how
LITTLE/short/inexpensive a mast, pole, tower, or other support would one
want-need to get reasonably good performance and cause the operator to
think he was doing better than, say, using his big vertical or dipole (at
say 35 feet high) on the upper bands, say on 20 M / 15M /10 M ?
In other words, what small tribander yagi beam could one put on a on a
light tower or, even better, a mast and lightweight rotator - and get
reasonable satisfaction on the air ? Not nirvana, but happiness.
If so, what might it look be -- I am asking how much is just enough - what
would at the other end of the antenna spectrum from a 100 foot
tower with the biggest M2 or SteppIR yagi beam on it. What would be
"good enough" (knowing it is not best) ?
For the purpose of my question, please assume all new parts, no used
stuff, when estimating cost or suggesting what to use. That would give
me worst case cost scenario...
Thanks Loads.

Possibly of zero value.
2)
If the choice were a tribander @ 50' vs. a vertical for 20... I'd pick the
beam, and go vertical for 40, 80, 160.
