Antenna 40 Meter Links →
Un Dipolo economico e facile per 40/80 metri
Un prototipo della nota W3DZZ, che riporta qualche modifica sulla lunghezza fisica e sul Circuito L-C
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
Electrically short dipole antenna for the 40m band
An antenna whose electrical conductor is much smaller than half the operating wavelength is an electrically short antenna, e.g., quarter wave dipole
40 meters 3 element wire yagi
It is important that the elements be placed so that they are parallel to each other and orthogonal to the support cable

23cm Yagi Antenna building Finished antenna at 1275 MHz SWR under 1:1.5 at resonant frequency
50 MHz preamp Gain 26dB with the BFG135 Preamps for 144 and 430 MHz, for 50 MHz, the BFG135a is a cheap transistor and in my view rather strong. It is not easily damaged by static discharge or RF power. FG connection
