Author:  Kevin Loughin (KB9RLW). Comment: Kevin has done an excellent job of explaining how to convert an old TV rabbit ears antenna into a simple, inexpensive, and effective 2 meter antenna.  I've built several of these 2 meter antennas from discarded televisions found at my local recycling center.  Like Kevin, I enjoy "re-purposing" old parts and equipment for my various amateur/ham radio projects.  This antenna is small, lightweight, and totally "stealthy" for those living in deed-restricted housing (HOAs and CC&Rs).  Kevin takes you step-by-step through the antenna making modifications.  This is an easy, rewarding, and ultra cheap project that can be used for both home and portable operations.  Views expressed in

2 Meter Full Wave Loop-The Magic Wand Antenna. Post #1437.

If you enjoy antenna experiments, you may find this 2 meter full wave loop an intriguing project.  This antenna is based on the original Ed Fong Dual Band VHF/UHF (2m/70cm) J-Pole PVC Pipe Antenna.  Most of the materials can be bought at your neighborhood hardware or building supply outlet.  With a good set of tools and a few hours of work in your shack, you will have an antenna with some interesting characteristics.  You could even use this antenna in stealth mode to avoid nosey neighbors in deed-controlled housing (HOAs and CC&Rs).

Multi-band hf loop antenna. Post #1436.

Multi-band hf loop antenna. https://www.surriel.com/radio/multi-band-hf-loop-antenna. Accessed on 20 March 2018, 0028 UTC, Post #1436. Author:  Rik van Riel (AB1KW). Please click link or enter title URL into your browser search box to read the full article. Comment: If you're forced to use one HF antenna for your Amateur Radio activities, you may want to consider this simple, effective multi-band loop antenna from Rik van Riel (AB1KW). According to Rik, this loop will permit operation on all Amateur Radio bands from 80 meters to 10 meters.  The antenna uses 86 meters (approximately 242 feet of wire for the multiband loop), which is bit small for 80, 17, and 12 meters, a tad large for 40 and 30 meters, and just right for 20, 15, and 10 meters.  An antenna transmatch  (i.e. "tuner") can compensate for some of the length measurements. Rik does an excellent job of discussing all aspects of designing a resonant hf loop antenna, examining the gain and radiation pat

If you have a small yard and don't have room for a full-sized HF dipole antenna, N4TMA may have a solution for your.  N4TMA made this video for a friend, showing how a bit of ingenuity, some old CB antennas, some extra wire, a few mounts, and other material available locally can get you on the air with a decent signal.  If you're willing to accept a few trade offs in terms of power, bandwidth, and efficiency, you can have a functioning HF antenna ready for your next QSO in just a few hours. Remember the old saying:  "A compromise antenna is better than no antenna."

Homebrew EH Antenna for 40M band. Post #1434.

If you can't see this video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=DWR5d7t0Aw. Here's an interesting antenna idea that has generated lots of comments over the past few years. Even broadcast stations have experimented with the EH antenna idea, with varying results.  Some claim the EH antenna is no better than a dummy load, while others believe the concept is workable if you pay strict attention to its design parameters. In this video, OM0ET makes a 40 meter EH antenna based on a design by WB5CXC.  Apparently, the homebrew EH antenna works for him.  You may want to build one yourself and see what results you have.  This could be an interesting experiment.
