Interesting subject. The two big X factors in success that are seldom mentioned
are propagation and most importantly-operating skills. The other day I set out
for a short SOTA activation wanting to set up a portable 2 element vertical
beam developed by JP1QEC. I’ve used it with good results on 2
It would seem that using the Diversity Reception capability in several
current radios, would be an ideal way to evaluate two antennas, although, I
realize having both antennas up at the same time is not always possible.

Kevin is on to something when he compares antennas instantly which I assume
from his description. Most antenna anecdotes state something like "It works
much better than...I had up previously. But, both antennas aren't up and in
use at the same time.
My good friend Alan, K0BG, puts it very well.
I agree with Joseph. I have been able to bust pileups on recent
dxpeditions such as VP8PJ, VP6R, and VP6D on 30m and 60m, even though I
don't have antennas on those bands. The SWR was 10:1 on my 80/40 vertical,
and even though I was blissfully aware of the high voltages in the tuner,

K2MIJ is a big fan of - shall we say - unorthodox antennas. His claim to
fame, as it were, is the “Limbo Stick” cut for various bands. You can find
him on almost any Internet search. He’s also set up using folding aluminum
chairs as radiators and tape measures as counterpoises. Quite ingenious
Even in my professional life I operate using a philosophy of three simple
rules. As for antennas:
1. I get a match.
2. I can hear the other Ham.
3. They can hear me.
Simple enough, and I have made contacts on my KX2 using an umbrella frame on a
stick.

One of my favorite portable antennas is a homebrewed link dipole for 40,
30, and 20m. I tuned it very carefully for the middle of the CW portion of
each band, but it's still fairly well tuned in the SSB portions of 40 and
20. I still use a tuner with it for phone, though, just to keep from

Let's start with Kevin KD5ONS and his 40m vertical. A great monobander and I'm
sure it performs very well on that band. He tells us it works great on most
other HF bands as well, using the wonderful Elecraft matching ability. Had he
stayed with that one antenna on that one band
I prefer to use resonant antennas, either single or multi band and not use a
tuner, however, I have encountered that even resonant antennas are not always
so due to ground conditions,
Case in point, two weeks ago we hiked to the summit of Sentinel Mountain in
Baxter State Park. I carried my KX3,

Same here. Most antennas that we can install are some form of

My new antenna works well on 80, 40, 30, and 20 meters. I have not

For what it may be worth, I'm a staunch supporter of antenna tuners
myself. I previously used one for many years to get 5 band operation

Scottsdale, and I just built a high power monster to get full coverage
of the low band

Our friend made strong mention of SOTA and the KX series of portable rigs and
those users often require a multi-band antenna for simplicity and to keep the
weight down. Our friend's 40m vertical is also being used on 20m, so, it's
reasonable to assume he desires multi-band perform
That's a lot of bad advice all rolled into one.
1. Low voltage at the antenna does not mean low voltage at the shack
end of the feedline. That's why it's called VSWR.
2. Low voltage at the antenna does not mean low voltages internal to
the tuner, which can be quite high depending upon the
The new, resonant antenna performs well. It is much quieter than the

Actually, a pretty casual Google search will turn up homebrew designs
using a can of high-concentration salt water as an inexpensive (though
not very stable) dummy load.
And that's pretty much what the salt water "antenna" would be.

Seawater has electrical conductivity of seven *orders* of magnitude
lower than copper!
As a quick and dirty check, I created a simple 10m ground plane
antenna in NEC-4.

This has been debunked by antenna design experts (one of whom

because of the extreme losses in the conductivity
