Build a simple magnetic loop antenna
For the main loop I used a soft copper tube, diameter is 10 mm, length about 3 meter. The smaller loop is about 60 cm in length diameter 1/5 of the main loop, material is 1,5 square mm copperwire

Loop Magnetica 40 a 15m P/Movil
Magnetic Loop, made for bands between 40 and 15 meters. According to the diameter we can choose the bands or higher or lower
Loop Magnetica Bibanda 20-40metri
Questa antenna e' costruita in cavo coassiale e non richiede un condensatore di sintonia.Il prototipo e' nato per la banda dei 40m
Loop Magnetico RX
Variable 365pf condenser 1 section only of air + three fixed condensers of 15'0pf, 1 of 680pf and 470pf
The K9AY loop antenna for 160 and 80m bands
You don't have the space to put up a 4 beverage antenna's, an EWE or a 4-square and want 'good ears' on 160 and 80m? No problems try a K9AY loop 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
