Low Band dei 80-30 meter Antenna diversa dalle usuali a dipolo, ma che si e' dimostrata validissima nell'operare nelle bande basse dei 80-30m

40m Moxon Antenna The input impedance of our antenna is 50 ohms, balun 1: 1. with coaxial RG213 of 15 cm in diameter and 5-6 turns from the winding

4 elements Yagi 10 meter band For 28.000 - 29.000 MHz 4 elem. boom 3.83m long

Sequencer with cw memory keyer The tuning is simple unscrew nuts and move the clamps up or down until you get the SWR correct

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

30-40 Meter Vertical

30-40-meter vertical I built this antenna specially to be used on the 30 meter band. The coil used is big enough to cover the 40 meter band as well. The coil is a bit over kill to just run 200 watts through it, but it was given to me. This coil came from a broadcast transmitter

40m 2el Yagi linear load

40m 2el Yagi linear load This 40m yagi, which shows very high performance on our tests, isn't ispired from any other model. Lots of yagi models are analyzed and this model figured out. The most spesific part of this model is having belove 1:5 SWR value and 175 khz bandwith
