Antenna Duplex duplexer Links →
4-way Splitter/Combiner
The Spectrum-Analyser screen shows a frequency of 144.370 MHz were the marker is at that moment
6m duplexer construction
Construction of a set of WB5WPA style 6 meter notch duplexer
A triplexer for shortwave, 2 m and 70 cm
A triplexer for shortwave, 2 m and 70 cm I used CuAg wire for the coils, normal Cu wire should work too. The capacitors are 500 Volt types, you may order them here
A low cost UHF/VHF duplexer
Duplexers for dual band radio are usually high pass filter and low pass filter combined in the same box

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
