A Three Element Hex Beam for 50 MHz This is a hex beam for six meters.It has three elements with a turning radius of 54 inches |
Antenna 3 elementi per la banda dei 4m 70MHz YAGI a 3 elementi per la banda UHF dei 70 cm,l'antenna presenta ROS di 1,2 ed e' centrata circa a 432,5 MHz |
Antenna delta loop per i 6 metri La Delta Loop, come tutte le antenne quad, e' un'antenna composta da una spira di filo, alimentata da un cavo coassiale |
Antenna direttiva 50 Mhz HB9CV per i 6 metri è composta di due elementi a circa mezza onda, ed una traversa da un ottavo, da un gamma match, un attacco SO239, un condensatore in serie, costruito in vetronite ramata del valore di circa 25pF |
Linear loaded short dipole 21Mhz For my amateur radio activities on the HF bands I only have a 3.6 m wide balcony available for antennas. After some study I decided to experiment with a shortened dipole for the 15 m band
Rx antennas 4Square Rx Vertical Array My frequency design of 1.825 MHz a 90 degrees line would be 33,70 metersinstead of the previously calculated 33,27 m
Atu balanced feeder antenna system An ATU has the advantage of bringing the feeder-antenna system to resonance, act as a band pass filter both on receive and transmit and a low SWR
