33 MHz diplexer
This is optional, but the diplexer should be mounted as close to the mixer's IF output as possible

Antenna Duplex duplexer Links →
Look on schematic diagramm MFJ duplexer
For connect TX antenna and RX converter i suppose that RX converter has 145 IF Im use old MFJ-916 duplexer with 144/440 label
Micro-Duplexer
A good duplexer can make the difference between hearing AO-27 full quieting and hearing a bunch of muffled static. The main purpose of a duplexer is to separate the transmit and receive signals
Make yourself a Diplexer
By having to change coax connectors when you change bands? Here's a simple way to do it automatically, with very low loss
Micro Duplexer for 70cm and 2M
The KI0AG Micro Duplexer very small, light weight and ideal to go inside the boom ofthe antenna

A prototype to see how it came out and here are the results of the experiment

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
