Six-Meter Heliax Duplexer/Repeater Project
A Six Meter Duplexer designed by WB5WPA that physically consists of discarded pieces of 1-5/8" Andrews Heliax that are cut to resonate at quarter wavelength of the notch frequency
Stacking with homemade Power Splitters
The basis of the power splitters/combiners is a construction of a square tube for the outer conductor and a round tube for the inner conductor. It forms a quarterwave coaxial impedance transformer
The duplexer
This is a very nice project, especially for those Icom 706's that have an HF / 6m antenna connector as well as a VHF / UHF connector to combine both outputs to a single all band antenna
Triplexer HF/50 Mhz 144 432 Mhz
Necessita' di ricevere segnali da tutte le direzioni, senza dover stare a ruotare continuamente le antenne direttive
Two Antenna Stack Match
Solves antenna matching problem with two phased antennas Provides convenient and flexible antenna switchingVacuum relays provide reliable high power operation
