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
Coaxial Cabling Lengths between the Duplexer
Any idea what length of coax I should run from the transmitter and receiver to the duplexer
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

50MHz to 28MHz RX Converter The concept of the rx converter is quite simple and nothing really new. the local oscillator is a standard colpitts crystal oscillator producing the 22mhz lo signal
