Antenna Delta loop bidirettiva
Questa e' una antenna adatta per HF realizzabile senza troppe difficolta', l'unico inconveniente e' che necessita possedere di un discreto spazio dove installarla e di almeno quattro supporti a cui agganciare i loop

Horizontal loop antenna construction
The Horizontal Loop, also known as the Loop Skywire Antenna, is an old but very effective design
L'Antenne Delta Loop
To calculate a Delta - Loop antenna the formula is relatively simple: we take the formula 1005 / F, here if we want the Delta Loop to be qrv any Band it must be calculated on the lowest frequency, we take as an example the 3,500 Khz
2 Elements 20m Delta Loop
For this project I started describes the building of a HF three bands 10-15-20 aluminium delta loop, but I limited the design to 20m band only

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
