La antena de cuadro o Magnetic Loop
The first antenna of this type that I made, was something similar to a frame antenna similar to those used by the old AM radio
Loop 1.5-30 MHz with preamplifier
The range of 2.7 to 7.3 MHz. The variable tuning capacitor is a 3 recovery air cages on an old tube radio receiver

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
