[Elecraft] Portable Power

[Erlend Grimseid]

+1 on the lifepo4. 4 in series gives an adequate voltage for most portable
ham radios. From just under 14v, til they emtpty at about 8v. Get or build
a pack with protection circuit as over charging an discharging  ruins them
pretty quickly. Tons of info on the web. Just google it.

As for antennas. Look at sotabeams, he i uk based and have a great
selection of portable wire antennas and the stuff you need if you want to
build your own. Lighter, cheaper and more efficient than the buddipole.
Take a look at an linked dipole for the bands you plan on using.

Good luck on you sota activation's. Hope to catch you on an s2s soon.
