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
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
