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.

Intro

Configuration

80 Metres BLUE = 12m above ground (0.15 wavelength) RED = 10m above ground (0.12 wavelength)

40 Metres BLUE = 12 m above ground (0.30 wavelength) RED = 10m above ground (0.25 wavelength)

20 Metres - Azimuth at 5 degrees elevation BLUE = 12m above ground (0.60 wavelength) RED = 10m above ground (0.50 wavelength)

BLUE = 12m above ground (0.80 wavelength) RED = 10m above ground (0.67 wavelength)
