Has anyone tried using a Hamstick antenna on harmonics?
IE, 40 meter hamstick on 15 meters?  What where the results?  A non loaded 40 meter antenna will work well on 15 meters as a 3/4wl antenna.  Thanks, Jerry K8gww

Spirally wound antennas have a lot of distributed capacitance which negate their use other than for the band they were designed for. They indeed may "appear" to load, but the losses would be enormous.

I tested it and it does not work. But who can't afford the $21 for a 15m one anyway! ;-)

Get the little VP-1 tri-band adapter by Hustler which will allow you to mount 4 hamsticks at the same time. Use the adapter at the base of the Iron Horse triple-5" magmount.

I use only 2 while driving and 4 when fixed! Instant QSY is great and the only interaction to watch anf tune for is if 12 & 10m sticks are used together. The 10m band center frequency will be increased but that can be accounted for.

This multiband use of the Hustler adapter adds real utility to the hamstick type antennas!

Has anyone mounted a Pro-am PHF-160B
(160 meters) antenna on top of
a 80-10m Screwdriver antenna?  I was
thinking the screwdriver coil might
allow for tuning of the 160 meter antenna.
