Nel gamma match, per cancellare la reattanza induttiva introdotta dal sistema, basta aggiungere il condensatore C2
Antenna bibanda 15-20mt ad " x "
Ogni semielemento e' formato da quattro sezioni telescopiche di tubo in alluminio anticorodal da 016 a 25 mm con spessore 1 o 1,5 mm
Antenna yagi 121,5 MHz a 4 elements
This 4-element antenna has been specially calculated for searches for aviation distress beacons on 121.5 MHz, relatively large gain close to 8 dBd, good front-back ratio more than 20 dB
Antenne yagi 5 elements 403 MHz
This antenna was developed for the direction finding of meteorological radio probes emitting between 400 and 406 MHz
