43' Vertical and the K2 tuner

[daleputnam]

MFJ1793, is a 41 foot vertical, and works with a 20 meter element, and a single 80/40 element, a top hat and a steel roof adds up to workable on 80 - 15...

  NOT on 160. Not even. But quite nice on the rest.

Ya need a bigger top hat...

I ran my second ARRL160 with a 42' vertical piece of wire and a 130' wire top hat with 30 radials between 30 and 70' long... made the top 10 with it LP. But I don't think it would have played well on 40 and maybe only so-so on 80 without traps.

By the way you stand out quite well on 160 with whatever you're using Dale :o)

Thank you, this year I am using a pair of, soon to add at least one more, edzs on 160, with that being 360 foot long each, fed in the middle, at 50 foot. Improvements will be higher, and one more. The best vertical I've had was a NORD, with a 40 foot heighth, and 32 radials up to 1/4 wave long, on the ground. Next vertical will be a coffee can vertical, and I haven't yet decided if it will go on the steel roof, or if it goes on it's own radial field.

One never can tell real well how he is doing.. so I appreciate your comments, they are very welcome. I sure had fun in the Elecraft QP... just couldn't stay very long.

thank you,

Steve and All,

Well, not exactly!  You remember those Gothams huh!  I had
one of them.  Back in 1956 I bought a Gotham V80 when we
first moved to New Mexico--no trees there like I had in
Oregon!  All the V80 consisted of was a long piece of
aluminum and a loading coil!  I don't remember how tall it
was, but it may well have been something like 22 feet.  It
was base loaded, and not all that easy to use multi-band,
particularly if you had it on the roof!  It wasn't hard to
make the decision to use it as a monoband vertical, and mine
became a 20 meter vertical.  I don't remember for sure, but
I think the coil became superfluous!  If I'd been smarter, I
would have set it up like Jim Duffey suggested, although I
don't remember anyone selling remote tuners back then.

Now throw the "then relatively new" monimatch SWR meter into the mix.  Add
radials to the shortened base-fed vertical and watch line SWR increase.  To
many novices, the thinking is that if the SWR is better without radials,
then why use them?

Was it Gotham that used corrugated aluminum tubing?   Seem to remember
one antenna that we could never get the pieces apart.
The corrugations caused too much binding.  Nobody used Alumilox any such
thing in those days.
