Tested a portable elevated "V" today

[nikdfish]

I got around to testing a printed "V" antenna base design today. The base was done with M10x1.5 threaded inserts, but I have adapters to permit use of whips with a 3/8-24 thread. This was an initial test print with modification. The current model is more refined.

I mounted the base on a fiberglass push-up pole with a ACME 3/4-5 threaded end, supported by a printed clamp on tripod. I used a couple of 102" telescopic whips, fully extended for the first test.

With the whips fully extended, it covers 11m @ < 1.5.

With the last segment of the whip shortened to 10", it covers 10m @ < 2.

At some point I will be testing with a 220" whip in the vertical position & the two 102" whips in a downward (45 degree) angle as radials. I think 12, 15 & 20m should be usable without a transformer or coil. A small loading coil should enable 40m (& maybe 80m?).

I love it!! Messing around with that type of stuff and wire antennas is a ton of fun. Good Job.

a few years ago, on 17 meters, there was a guy that
vacationed down in Jamaica and he had an antenna
set up like that, right on the beach several feet
off the sand. I would talk to him during his
Winter vacation down there.
And also there was a guy that would
go to a park near Phoenix AZ and had the same set up.
He had a good signal here.
(He was not POTA, just his weekend thing at the park)

2 quarter wave radiators in a mild upward
going V antenna on 17 meters. 100 watts.

there is a Ham in northern CA selling that set up.

I see on your set up, you can have a vertical with
2 downward pointing radials.

make a 17 meter version.

but if you use it for POTA on 17 meters,
the "NAZI Hams" will get mad and say POTA is
not allowed on 17 meters. also "Sad HAMS" and
"Grumpy HAMS" may get annoyed also.

when I repair these export "CB" radios and amplifiers
that can go to 29.6 MHz FM and I use them there,
tell them what I am using, the "NAZI Hams" get mad.
When testing on 29 MHz AM and I say I am using a
"Ranger" they assume I am using an old Johnson Viking
Ranger tube transmitter. So I correct them and tell
them about RCI radios. oh, and when I mention a
PALOMAR amplifier, yikes!

I have all this stuff correctly biased and modulated.
sounding good on my Motorola Service Monitor.

hopefully someone will get a giggle out of this.
