ham antenna duplexers & triplexers Items 1 to 9 of 12 total Show 9 15 30 All per page. Duplexers expect to see a 50 ohm load on every port, and many transmitters, many receivers and some antennas are not. A duplexer is 50 ohms only at resonance, anywhere else it is reactive. The attached feedline is 50 ohms, and the receiver or transmitter is SUPPOSED to be 50 ohms. Duplexer and diplexer is a curation of 30 resources about, Diplexer for 2m and 70 cm, Six Meter Heliax Duplexer Construction, AA5TB Antenna Coupler / SWR Bridge, Homebrew cavity resonator/duplexer for 2m repeater, Diplexer 2m 70cm. Resources listed under Duplexer category belongs to Technical Reference main collection, and get reviewed and rated by amateur radio operators.
Uninformed people sometimes get the two confused and call a diplexer a duplexer, and vice versa. Comet are amateur radio duplexers polarized
needs to use the proper term. A diplexer or triplexer or quadplexeris a bandpass filtering unit, usually L-C based, that allows multiple transmitters, or receivers on different bands to use a single feedline, antenna, or both. Another example, this one specific: If you had a separate HF antenna and a 6m antenna, then you are amateur radio duplexers polarized
use a diplexer with a breakpoint between 10m and 6m to split the HF and 6m to two antennas.
