Thanks to Michael Martens (KB9VBR) for this fascinating video on Off Center Fed (OCF) HF Antennas. Michael built this variant of the classic Windom Antenna for the 2020 ARRL Field Day event.  The original antenna design belongs to Loren Windom (W8GZ), who published his experiments in the September 1929 "QST" Magazine. Here are some comments from Michael: I build an 80 meter off center fed dipole antenna for this year's ARRL Field Day Event.

What kind of antennas are suitable for "compromised spaces?" Josh Nass (KI6NAZ) tackled that question in a free-wheeling video-streamed program from 08 August 2020. The video contains several listener questions which confront radio amateurs operating in deed-controlled housing. The program offers a variety of possible solutions to HOA/CC&Rs restrictions.  Perhaps, Josh and his listeners can find an antenna solution for you. Here are some comments from Josh: Patron Pick August! What antennas should you look at setting up in compromised spaces? We'll talk about it tonight! http://www.Hamtactical.com ​ For all the Ham Radio Crash Course Merch! Thank you for the support!

Every radio amateur should have emergency antennas for the HF, VHF, and UHF bands. As Kevin Loughin (KB9RLW) points out, this antenna is probably "hidden" in your "junk box", just waiting to be assembled. Here are some comments and suggestions from Kevin: An old design that many new hams may not be familiar with. Easy to build with minimal tools, great emergency throw-it-together antenna.
