The DCTL Antenna Smallloop
The construction material is simply 300 ohm heavy duty TV twinlead
The Ferrite Rod Antenna
The ferrite has the effect of intensifying the magnetic field inside the loop. The is produced by the high permeability, of the ferrite material
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
Magnetic 80m band receiving antenna
Small active fully balanced an screened receiving loop antenna 15 kHz 36 MHz
Automatic Magnetic Loop Antenna Controller
This controller has been designed to automate the control of magnetic loop antennas

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
