Six-Meter Heliax Duplexer/Repeater Project
Consists of discarded pieces of 1-5/8" Andrews Heliax that are cut to resonate at quarter wavelength of the notch frequency

The duplexer
This is a very nice project, especially for those Icom 706 that have an HF / 6m antenna connector as well as a VHF UHF connector

Duplexer per la banda 144/430 MHz
Lo stadio VHF e' un filtro di Chebishev Passa Basso a 5 elementi con un'attenuazione di circa 50dB/ottava al di fuori della banda passante

33 MHz diplexer
Ahead of the IF amplifier on the 2nd mixer's IF output is a circuit called a diplexer

Make yourself a Diplexer
Here's a simple way to do it automatically, with very low loss, and so you can transmit, listen or scan at will
