The ATL-3 Loop Antenna
Tuned winding antennas always have a potential 6dB greater signal sensitivity, and provide a better signal to noise ratio than equally sized broadband designs
The magnetic loop
A 10 ft length of 5/16in copper tube gives a 39in diameter loop
Traveling Loop magnetic
The antenna is made with coaxial cable shorting the inner conductor to the braid
Variation on the Shielded-Loop AM Antenna
A common hula hoop is a readily available item that can be used to house a home-made shielded-loop AM antenna

23cm Yagi Antenna building Finished antenna at 1275 MHz SWR under 1:1.5 at resonant frequency
50 MHz preamp Gain 26dB with the BFG135 Preamps for 144 and 430 MHz, for 50 MHz, the BFG135a is a cheap transistor and in my view rather strong. It is not easily damaged by static discharge or RF power. FG connection
