George, KJ6VU, has a great podcast and accompanying web page with some interesting gear and DIY projects going on. They are presently doing a group build of a 1-30 MHz antenna analyzer based on the Arduino platform. Have a look and/or listen at www.hamradio360.com
I mentioned this on tonight’s tech net at 9 PM. While you are perusing that website, have a look around at a few other very interesting things. For instance, see George’s presentation from this year’s Dayton Hamvention, where he introduced the very handy portable end-fed antennas from his new company called PackTenna.
The presentation does a very good job of showing you how to wind some simple baluns (actually they are un-un’s) to get your 50 ohm feedline matched to the very high impedances of either a resonant, end-fed dipole, or a random-length end-fed antenna. Or…you could buy one ready-made from PackTenna for $89. If you go to www.packtenna.com and look around, be sure to read the QST magazine “test drive” of his antennas. Highly recommended.
