Stacking Formula for Long Yagis
Two identical yagis can be stacked so that their capture areas just touch. That distance will give close to the maximum achievable gain

Three-Element Antenna for 28 MHz
The 3 element is a commercial antenna by PAN International, which I slightly modified for good performance on the 10m Amateur-Radio band
Una 2 elementi yagi portatile
Una 2 elementiYagi per 1 10, 15 e 20 metri in cui i rispettivi dipoli irradianti alimentati dalla stessa linea coassiale
Xexbeam 5bands20m,17m,15m,12m,10m
The Hexbeam is a great little antenna! It should be high on your list of options if you want a design that can be "multi-banded
Yagi 2 elementi per i 18 mhz
Il punto fondamentale e la spaziatura tra il dipolo e' gli elementi parassiti, infatti questa misura va a variare le caratteristiche dell'antenna
Yagi 4 elementi per i 14 Mhz
Direttiva quattro elementi monobanda per i 14 MHz senza trappole

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
