Antenna delta loop 6 metri 50 MHz
L'impedenza caratteristica della Delta Loop, presenta un valore di circa 125 ohm, mentre il suo guadagno e' di circa 1,4 dBd

Antenna boomless tribanda per i 50/144/440 mhz
Questa realizzazione occupa poco spazio, e' leggera, non necessita del rotore

Chris Gare's 50MHz Power SplittersThe use of power splitters and combiners is widespread in amateur radio but the design of these circuits is often considered to be a 'black art


COAX antenna projects 2 and 6 meter
Uses formula for calculating the coax lengths 984 x .66/your frequency/4= 1/2 of the driven element, but I did not leave the 20% longer sections as I was not going to use insulators
