Antenna 10m 28 Mhz Links →
10-Meter Vertical
The length of the vertical wire to 17 ft 4 in and I had a SWR of 1.1 to 1 at 28.200 MHz.I had good SWR of 1.4 from 28.000 to 29.000 MHz
3 Element 28 MHz Yagi
By adjusting the length of the Gamma match and the series capacitor, the VSWR can be adjusted to 1.1:1 at 28.4 MHz
3 element yagi for 28Mhz
Design Frequency: 28.300 MHz, Usable Bandwidth: 600 kHz, Gain: > 7.5 dBi, Front/Back ratio: > 20 dB
3 y 4 Elementos 10 Mts
The macth range has a total length of 70 cm, from the connection point on the coaxial plug, to the end of the range rod
4 Element a V for 10 Mts
Una grande copertura di banda con basso ROS

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
