Sloper sloping dipoles 40mt-80mt
Having only a single vertical support or limited horizontal space might be a problem.Such a problem can be solved by mounting a dipole at a slope

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

Take off angle of horizontal antenna For horizontal polarization, the electric field will move sideways on a horizontal plane, while for vertical polarization it will oscillate up and down on a vertical plane
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
Calculo da Antena Bazooka A double bazooka antenna is a combination that has a complete coaxial wave multiplied by its velocity factor and a total end-to-end length of 1/4 wave for each side affected by another driver shortening facto
