Hamstick dipole for 80m
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.
