Hamstick dipoles work pretty well for 20m-10m. Not well for 40m
and terrible for 75m (unless the application is a special one
like the portable NVIS application in the latest QST).

Can one use open ladderline with a 20 mtr hamstick & the appropriate
tuner & work 20-10 mtrs.?

Bandwidth is very, very limited...

The problem with using hamsticks on higher frequencies is the loss in
the coil. The 20m hamstick has too much inductance for any higher
frequency and thus has more loss. Losses are probably worst case at the
self-resonant frequency but I don't know what that frequency is for a
20m hamstick and I don't have a 20m hamstick to test. Perhaps someone
with a 20m hamstick and an MFJ-259 will run that test and report the
results. In general, though, it is not a good idea to use hamsticks on
higher frequencies than their resonant frequencies.

However, using parallel 18 MHz hamsticks with ladder-line to cover 20m,
17m, and 15m is probably not a terrible idea.

Lakeview sells a dipole mount for use with its Hamsticks. It would
seem you could put the thing up, attach your coax feedline, and then
just change out Hamsticks for the appropos bands.

Sure. Don't know if it would be worth the effort, but it's
certainly possible. You're basically trading 'coax' problems
for 'ladderline' problems, there's a differnece in the mechanics.
No idea if the benifits would be worth the effort...

I received 2 75 meter Hamsticks today. I
ll let the group know how it goes.

It will go very, very narrow. 10-25 kc perhaps.

Hi All:

Been there, done that. Mine was about 65KHz wide and about 10 to 15db down
from the full size 80m dipole I put up to replace it. I had both up at the
same time and they were both at about the same height so it was a good
comparison. That said the hamstick dipole worked and I did make contacts on
it.

Russell,

What are you comparing this to or using it for?

Are you just having fun experimenting or do you have a planned use for
this antenna?
