Why bother?
Insert an 8' piece of fiberglass tubing in the top ... now you have a
50' +/- support. Install two 8' pieces of PVC or fiberglass tubing in
a horizontal cross at 30 to 35'. On one, run your 80 meter wire - tie
it back to the tip of the antenna and
I personally love the idea of a 43 foot vertical. I use the Dx Engineering
Thunderbolt for 60 meters, it is 1.5 inches at the top. I collapse it down
to 33ft6in. Gives a fully resonant antenna on 40. Add a 17.5 foot wire with
outrigger (pvc supported on vert by hose clamp) and now you have
).

experience with 43 ft verticals myself but have heard a lot about them
and have been thinking about building one. I too would like to learn more.

Thanks Mike. Your observations about radiation angle and performance
are in good agreement with my modeling. Yes, the secret sauce is that 43

An interesting point I noticed modeling a 43 foot vertical was that, while
on 10 meters the main lobe is up around 50 degrees, the gain at low angles
is similar to a 1/4 wave ground plane antenna cut for 10 meters. That's
because the longer antenna has significant gain over a 1/4 wave antenna so
YES! You've hit the nail beautifully on the head, Ron. I just finished
preparing slides comparing a 43 ft ground-mounted vertical with a good
radial system on 20M, 15M, and 10M with a classic ground plane at 30 ft
and vertical dipole with a base at 30 ft for those bands.Looking at
performance
This has been an excellent discussion on the 43 foot vertical. I have one
installed in my back yard (DX Engineering). Very happy with it overall. It's
been an excellent performer on 20 meters, and good on other bands; I'm a casual
DX-er, but have worked 5 continents SSB with the 12 watt output

I use paralleled dipoles here, and I have limited the number of bands on
a single feedline to 3 bands, so I have one for 20, 15, and 10 meters,

with PVC spreaders.
Tuning them is a bit of a challenge, but if one tunes

43 ft verticals have become a popular antenna, and while they have some
strong points, they present a very high SWR on most bands, so they
require a serious tuner to get them to load.

I know this isn't an answer to the basic premise of the raised question,
but let me throw this out.
1. 43 ft. verticals that are ground mounted require a large, good ground
system.
2. Depending on the band you are operating, the assumption of a high
VSWR is correct.
3. High VSWRs on coax are
One can feed the 43 foot vertical with ladder line, and do the tuning in
the shack (yes, you can feed a vertical with balanced line), but if
feeding with coax, the best place for the matching network is at the
base of the antenna. Coax is good for an swr of 2.0 or less (depending

Barry, Number 1 is true if, and only if, the antenna is used below 14 MHz.
It's all a matter of feed
Don#x27;t worry about remoteing the tuner, but ditch the RG8X and use RG8 with
the least loss you can find.

Sure. It's called an End Fed Half Wave dipole. Oh, but to some, that's not an
