I am moving forward in my quest to go boat mobile from my pontoon boat this summer. I bought a 20M Hamstick at a local hamfest. The price was higher than I expected, so I didn't buy the second one for 17 Meters as I had planned. I set it up on the deck of the house with a mount and a couple of radials. It was pretty easy, using an Autek RF-1 antenna analyzer, to adjust the stinger length for lowest SWR on 20M.

That got me to thinking- what if the stinger was a lot shorter? Could I use the 20M Hamstick on other bands? The Autek says with no stinger in place, the frequency of lowest SWR is around 26 MHz.

There's a "stop" inside the lower section that prevents lowering the stinger more than a couple of inches. Has anyone used cut-down stingers to enable multiple band operation with a single Hamstick?

It looks like the stinger is about the equivalent of #10 wire. I will be buying some wire and conducting more tests (cutting the wire to different lengths). I'll report back with the results here.

P.S. If you enjoy experimenting with antennas, an analyzer (Autek, MFJ, etc.) is a great tool to have.
