Thanks to Ray (G4NSJ) of the "Radio Workshop" for this critical review of the HF360 HF Antenna. Ray conducts a series of basic tests on this antenna and finds some serious flaws. Here are some comments from RaY: I've installed an HF360 vertical HF aerial which apparently covers 80 to 10 metres. Here are my findings. ----- Thanks for joining us today.

Ham Radio-An end-fed half wave cage antenna

Thanks to Kevin Loughin (KB9RLW) for this fascinating comparison between a single wire antenna and a "classic" cage dipole. This antenna was designed for the 20m and 10m Amateur Radio Bands. According to Kevin, the cage antenna was more broadbanded than the simple wire antenna--something you may need for a home or portable ham station antenna. Here are some comments from Kevin: Another comparison between a single wire and a cage arrangement. This time on the end fed half wave antenna.

Amateur Radio and camping go together quite well--you get a chance to enjoy nature in fairly quiet surroundings while pursuing ham radio contacts with your emergency communications gear. In this video from "Tinker John" (W5CYF), we get several suggestions on how to mount your antenna during that camping trip. Here are some comments from John: A slightly modified 2 inch clamp makes an easy and handy antenna mount for 'hamstick' style antennas.

Thanks to "Commsprepper" for another great idea for making an emergency HF antenna.  In this case, a Chameleon Antennas' Hybrid-Micro base is used to support a random length long wire antenna. Here's some more information: Short video on my field expedient long-wire antenna with Chameleon Antennas' Hybrid-Micro base. http://chameleonantenna.com/ ----- Thanks for joining us today.

The Doublet Antenna-A Ham Radio Classic

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=xq07cBl_TbM This is post 2601 in a continuing series of simple ham radio antennas. One of the pleasures of Amateur Radio is the option of antenna experimentation.  Building your own antenna is educational, sometimes frustrating, and often inexpensive. In this video from Johnny of "Signal Search", we design, build, and test the "classic doublet antenna." If you need a multiband HF antenna, then the doublet antenna is worth considering.  Have fun! ----- Thanks for joining us today. Aloha es 73 de Russ (KH6JRM).  

Alex HamPack Magnetic Loop Antenna Review

If you need a compact, "stealthy", and portable HF antenna, then the new Alex HamPack Magnetic Loop Antenna may be for you. Peter of UK's Waters & Stanton Ham Radio Store gives us an excellent review of this easy-to-use portable antenna. This antenna would be a good choice for those living in deed-restricted housing. ----- Thanks for joining us today. Aloha es 73 de Russ (KH6JRM).  

Ground radials for vertical antennas

Image
The key to an efficient vertical antenna is a good ground radial or counterpoise system. In this video from Callum McCormick (M0MCX) we get a few suggestions on how to design, install, and test an experimental ground radial system. If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=M0qSRjltgoo This is post 2599 in a continuing series of simple ham radio antennas. Here are some comment from Callum: I have made a decision made to cut 32 radials at 10m long. That's 4 wavelengths of radials for 80m band - my lowest target frequency. At 40m, that's 8 wavelengths and for 20m band, I am running 16 wavelengths! I should be OK. Callum.
