Simple Ham Radio Antennas

Here's a nice accessory for radio amateurs using short length vertical antennas. Mcso911 takes us step-by-step through the design, construction, and testing of an air-wound coil that permits 20-40 meter operation from a single vertical antenna element.

Here's a great antenna idea from Tim (G5TM).  Just combine a MRQ 213 Telescoping Mobile Antenna with the "Slidwinder Coil" and you get a decent HF antenna for both mobile and home use.

Here are some comments from Tim (G5TM): Let’s combine the MRQ 213 telescopic antenna with the Slidewinder Coil. It worked very well!

Thanks to Andy (VK2AAK) and Bruce (VK2EM) for these "square" magnetic loop HF antennas.  According to Andy, one loop covers 14 MHz to 30 MHz, while the other works best at 50-54 MHz.  If you can't see the video, please insert this title URL into your browser search box:   https://www.youtube.com/watch?v=xUhS6mGdlRw This is post 2376 in a continuing series of simple ham radio antennas. Here are some comments from Andy (VK2AAK): Mechanical details for a couple of simple home made magnetic loop antennas. One covering from around 14 MHz up to beyond 30 MHz, the other covering the 6m band. These loops were both originally built by Bruce VK2EM who kindly gifted them to me. I subsequently made some mechanical changes, added the square feed loops along with a reduction drive and a switch to add some fixed capacitance. The antennas are ideal for portable and QRP use up to 30 to 40 Watts depending on the variable capacitor used. ----- Thanks for joining us today. Aloha es 73 de Ru

In part 3 of his vertical antenna project, Callum (M0MCX) finishes the ground plate and tilt-over mast for his new antenna.

Here are some general comments from Callum as he wraps up his antenna project: I finished the project! Fantastic way of tilting over my vertical antennas. I will review this again in a few weeks to see what I learned - watch out for that video.

Here's part 2 of Callum's (M0MCX) Tilt-Over Vertical Antenna project. In this video, Callum fabricates a "ground tube" and "ground plate" for the tilt-over vertical antenna.

Here's a useful accessory for radio amateurs using vertical HF antennas--a cheap tilt-over mast. Callum (M0MCX) takes us through the design, building, installation, and testing of this project for those of us who need to disguise our antennas or to protect our verticals from thunderstorms or other foul weather. Just raise and lower the mast to fit your operating schedule.

Thanks to Tim (G5TM) for suggesting another way of operating on the 40 meter Amateur Radio Band in a restricted space environment. As for myself, I use a doublet HF antenna fed into a "balanced tuner" (transmatch) to get good results on 40 meters.  Both approaches are decent compromises where space is a premium.
