Thanks, that is a great resource.
Here's my own design for an end-fed version, OCEF-Dipole (designed for use with
Elecraft T1 ATU) that I've used for travel with my miniature DX-go-bag station.
It needs just one support, you can hang it from the end egg insulator, or droop
it over a fiberglass tent pole. It rolls up neatly into a small 1Q zip lock bag;
tunes 3.5 - 52 MHz. Worked all over USA, Oceania, and Europe on 2.5-5 W with it.

You can also see it deployed at http://www.qrz.com/db/ke4pt
A few folks have copied this design and used it with good success.
Thanks again
