The slot allows for a 120Pf 5KV working disc capacitor to be fixed in place to allow operation on 40m.Remember also that even with only a few watts of RF power, magnetic loop antennas produce very high voltages across the capacitor(s) and can cause nasty RF burns if touched while transmitting.

The K4VX Linear-Loaded Dipole for 7 MHz 80-160 antenna for the small garden - PA1M - Amateur Radio During the PACC 2013 I used this antenna for 160 meters. Sometimes on 80 meters but there the 80 meters 2 * 20 meter dipole fed with open wire gave me more qso’s. The tower on the right in the picture supports the antenna as described above. The small mast through the roof on the left supports the top wire to the house.

I came across an interesting antenna the other day while looking at some antenna files with my antenna modeling software. It was called the "K5RP Magnetic Slot Antenna"I thought this would be a perfect DX antenna for me on 40 or 80 Meters. Delta Loop Antenna 80 Meters, Видео, Смотреть онлайн

Magnetic loop antennas are small and efficient shortwave antennas, the gain is comparable to dipole. BTV from Poland manufactures magneticFrequency range is selected by two jumper connections on top of the box. One jumper is responsible for the operation on 80m, while the other one selects...
Hf skeleton slot antenna | Page 2 | QRZ Forums I'm confused about the explanation on that site. It talks about this antenna like it's some kind of "skeleton slot" magnetic loop thing. But if you look at the diagram, it's just a 2-wavelength loop, neatly arranged so that the current maxima all take place on the vertical legs. 80 Meter Antenna Projects : Antenna projects for 80 meters ...
