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
50 Mhz 2el HB9CV
50 Mhz 2el HB9CV for band 6 meter
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

40m Compact 4-Square Antenna Compact 4-Square Antenna – EA5AVL The EA5AVL 40M Compact 4-Square Antenna was designed to provide excellent DX communications on the 40m band
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
Spiderbeam 10-15-20m E' una Yagi tribanda full-size leggera, fatta di tubi in vetroresina e filo
