Ham Radio: Loop Antenna for 80 metres to 10 metres


 

This full-wave 80 meter horizontal loop is my favorite multiband HF antenna. 

Before I moved away from my Puna property (Hawaii Island), I used several trees to support this large, but stable antenna.  I even built a full-wave loop to receive analog television channels (before digital transmission format) from Honolulu.

But now, I am using HF verticals and under the house loops for my main antennas...surely miss the old HF loop in the trees!

In this video, Tim (G5TM) takes you through the entire creation, build, testing, and use procedure for one of the best HF antennas in the hobby.  Of course, space requirements can put a dent in those plans.

Here are some comments from Tim (G5TM):

Thanks again to Rick, DJ0IP for publishing details of this antenna which he says provides great gain at higher angles for 80 and 40 metres as well as very good gain 20 metres through 10 metres. Let’s use MMANA-gal modelling to see if this agrees. Check out Rick’s website here: https://www.dj0ip.de/my-favorite-ante... Connect with my channel by subscribing and commenting.

"Big Hat" Vertical Antenna. Post #1422.

If you can't see this video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=xgOqP8uPEPc. Here's an interesting antenna design for radio amateurs exploring the 630 meter and 2200 meter amateur radio bands.  This classic antenna is basically a top loaded vertical designed for frequencies below the standard broadcast band (472 kHz and 137 kHz).  Even though this antenna is inefficient, a digital signal using the FT8 protocol should get you some contacts.  Good luck!

Antenna for Condo Backyard-Stealth. Post #1542.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=MXTYTytR56A. Don't let deed-restricted properties (HOA/CC&R) stop you from enjoying Amateur Radio.  In this video from AC2RJ, we see how some well-placed trees, a camera tripod, a telescoping fiberglass mast, and a "V" antenna can get you on the air without a lot of effort.  Add an antenna "tuner", a sturdy rig, such as the Yaesu FT-817, a microphone/cw key, and a simple grounding system, and you have a fully functional, nearly invisible ham station in your backyard.

G5RV Multi Band HF Dipole Antenna. Post #1555.

Image
If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=aeNHIQ_j4Dk This well-produced and richly illustrated tutorial on the classic G5RV HF Dipole Antenna was presented to the Brandon Amateur Radio Society in Brandon, Florida in 2017 by Bernie Huth (W4BGH).  Bernie does an excellent job of  explaining the pros and cons of this popular HF antenna from the late Louis Varney (G5RV).  Although Varney envisioned his design primarily as a 3/2 wavelength antenna for the 20 meter Amateur Radio band, radio amateurs have used the antenna for multiband use.  The G5RV is an excellent choice for the 20 meter band.  Performance on other HF Amateur Radio bands is good enough to qualify as stand alone HF antenna if you can only erect one HF antenna.
