What do you switch to at night when it doesn't
get dark? :-)

Dammit Cecil - not when I'm drinking coffee! hehehe 8^)

My map of Alaska. :/

Hi Jouko,

I made up a 4 band "spider" mount, to which you can screw in 4 sets of
hamsticks. I have a full set of hamstick whips from 80m down to 6m.

So I have a multiband hamstick dipole array!

When one thinks about the feedpoint impedance, even without the capacitive
disk, it certainly should be lower, but as I am using them at 7 metres from
groundlevel in a portable situation, I use a small antenna tuner.

At that height, they act like a "cloud warmer" or a NVIS antenna, so at 80m
its good for up to 350km. I haven't really given the other frequencies a try
yet.

Let me know I can email you with a few pics of my multiband "spider mount",
as I have a small lathe and milling machine in my workshop, it wasn't hard
to make.

John,

Yes I think using capasitive loading at the end of coil parts is the right
way to move the frequency.
What kind of results did you get with the hamstick dipole?
OK 50Ohm feedpoint resistance. I thought it is lower, but maybe it is so
due to high loss resistance in coils.

Most of my extender sections are from Henry, the

sections available in lengths from 1/2 foot to
5 feet and special lengths can be ordered.


I have a hustler 3 footer I use all the time..
Really cranks the performance up when you are
parked and can use a taller whip.
My normal whip is 11 ft, exactly center loaded,
and the mast makes it 14, with the coil at 8 ft.
I wish I had a 5 foot version. Might have to get
one of those for industrial strength use. :/
Of course, if I had another 5 ft mast, I'd end up
coupling them together and having 8 ft.
There is no such thing as overkill with a
stationary mobile setup. lol
An 8 ft mast would give me a total height of
19 ft, and the coil would be at 13 ft.
That would brown the food on 75/40 m... :-


How do you adjust the coil at that height? Of course I find that I
choose and spend most of my time on one band per mobile session, so
maybe it isn't a big problem.

The Hustler MO-1 and MO-2 masts have a hinge at 15" and 27" above the bottom
end: http://www.new-tronics.com/main/html/mobile__hf.html
They're 54" tall. The MO-3 is also 54" tall but doesn't have the hinge.
The MO-4 is 22" tall (no hinge).

We'd probably stretch "evening" until midnight. After that it's
"night", no matter how light.

Actually, we don't speak English at all, of course. :-)

HRBE-

I think it was the December, 2007, issue of QST that had an article on
the "Octopus" antenna made of 4 pairs of mobile whips for 75/40/20/15
meters. I plan to also add a vertical 10 Meter whip.

I've collected the parts but haven't assembled it yet. It will be
interesting to see how the monstrosity works!

Hope you enjoy 75m QRP.
