HAM Radio

MA5B mini beam installed.

I finally got my rotator and multi-band HF antenna on the tower this summer with the help of a friendly neighbor. This 3 element antenna is not a yagi, but a clever arrangement of single elements and matching circuitry that provide resonance without a turner on 20, 17, 12 & 10 meter amateur bands. It is a 2 element directional beam on 20 & 10 meters.

Despite the obvious sacrifice in gain, I'm nevertheless very pleased with the performance and flexibility of this antenna. I've not been very active so far, but I have received good reports from the US on 20, 12 and 10m.  

Above the MA5B is 5 element mono band yagi for 6m (50Mhz); I did plan to install a VHF directional, but there isn't really enough space without compromising the performance of the other antennas. So I'll mount it in a fixed position further down the tower.
