Subject: Re: [TowerTalk] Multiband yagi w/ 2 el 40m suggestion
> I'm looking for options for a multi-band yagi (either 10,15,20 or
10,12,15,17,20) that includes 2 el on 40m that could be installed on a
medium duty 50'-60' crank-up while keeping in mind the smallest footprint
possible for a city lot. I'm know Optibeam has several options and I think
Force-12 has one. Are there any other manufacturers that I'm missing? I'm
trying to gather all my options and compare the specs.
If it was me, I'd get a 3L SteppIR with the 30/40M trombone element.
Lots of band coverage and a monobander at all frequencies! Can't beat that
and it fits your smallest footprint parameter. I think they have one with 3
trombone elements that would result in significantly reduced element
lengths.
I don't remember the specifics but I think Force 12 has a couple of
models that fit your criteria. I'm not a big fan of their linear loading
scheme but they seem to work.
FYI for a rundown of a bunch of tribanders with measured on-the-air
performance, get a copy of our on-the-air tribander comparison report. It'll
give you some insight on which manufacturers offer decent antennas and
which ones don't. It's available from championradio.com.

## JK mid tri-40 https://jkantennas.com/jkmidtri.html albeit
expensive..and heavy...buts its done on NEC-4.
40-20-15-10m
## BTW, f12 has not used Linear loading in a long time. Their real old
yagis and rotary 40m dipoles can have the LL wires
swapped out to coils.
