Wideband active loop antenna
Wideband small magnetic loops WSM loop are used already 3-4 decades and I was curious to see what can be reached with them and to evaluate their usefulness as a wideband SDR input

Frame loop antennas are used on 136 for receiving and usually consist of around 50 turns of wire on a 1 metre or so square framework
Antenna LOOP per 80 metri, solo ricezione
The expected working band is that of 80 meters, electrically and estatically tuned LOOP
Magnetic loop square antenna
Operating bands tested 40m-30m-20m
A Receiving Array for 160 m Through 2200 m
Receiving antenna for LF-MF with good performance from 100 kHz through 2 MHz

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
