This is the collection of pictures relating to my small loop antenna. The design comes directly from the ARRL antenna book, there's hundreds of other examples of this antenna on the internet.

Specs for the loop:
Diameter: 6'2"
Circumference: 20 ft
Target frequency range: 3.5mhz - 10.2mhz (80m - 30m)
Actual frequency range: 3.4mhz - 9.6mhz (missed 30m, oh well)
bandwidth: less than 50khz (without tuning)
tuning capacitor: (ideally) 20pf - 380pf, ~10kv at 100w
The bandwidth is fairly small, so pretty much any change in frequency requires the tuning capacitor to be adjusted. The tuning affects reception as well as transmission, which is one of the advantages, as the narrow bandwith also rejects noise.

See also capacitor specs.

I also have pictures of other antennas.
