My travel antenna

An ongoing question on various online forums is "What is a good antenna for airline travel?"

Compact, inexpensive, easy to set up and effective - these are non-negotiable requirements for me:

17-foot (5m) whip -  offers a full 1/4-wavelength on any band, 10-20 meters. Collapses down to 19 inches (48cm). It has a 10mm thread so an adapter will be needed for the mount listed below. MFJ (sk) and other sources offer a similar whip (shown in photo) with a 3/8x24 thread but this version collapses only to 25 inches. I'd rather have the shorter whip even though it requires an adapter.

10mm to 3/8x24 adapter -  buy two because they're easy to lose ;-)

DXing: KX2 masquerading as a KH1

A cheap 51" (130cm) telescoping CB walkie-talkie antenna and conditions on 10-15 meters gave me the idea to treat my KX2 like a KH1.

Tuesday mornings can offer slow POTA activity but I was pleased with the results anyway from a peaceful little park about half an hour from home.

The weather was perfect and this project served as the perfect excuse to be outside.

In the following video, I made 10 contacts in 20 minutes. Those 10 contacts included 7 DXCC entities - all with a short whip antenna and a single ground radial.

When the bands are hot, amazing things are possible. Earlier this week I was able to work 4W8X on 10m CW from home with the KX2.

This weekend I'll be building a short coil to supplement the CB whip's internal coil with the idea of using the whip on 17/20 meters.

Various online calculators say I'll need 30 turns on a 1-inch form.
