6x2 Coaxial Remote Antenna Switch
select one of six antennas to either of two transceivers
A 6 to 1 hf antenna switch
Good coaxial cable is not cheap and a way to have several antennas available in the shack over only one excellent coax cable is a remote switch
A Coax Switch
The contacts in the slide switch have larger contact surfaces than many a bought coaxial switch
Automatic Antenna Switchr

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
