Diplex VHF UHF Separation de deux bandes
Here is a small assembly achievable in a short time and which allows to couple a VHF and UHF device on a dual-band antenna 144/432 via a single coaxial

Diplexer VHF – UHF
Per Due antenne, una J-Pole per i 145 MHz e una Super-J per i 433 MHz

Diplexer for 144/432 MHz
Simulation with ANSOFT Serenade SV8.5 and 8.7

Diplexer 2m / 70cm
The terms duplexer and diplexer are often confused.Both are devices that allow simultaneous operation on 2 different frequencies.The diplexer separates between 2 bands, the duplexer separates 2 frequencies in the same band

Diplexer HF + 6m / 2m + 70cm
These terms are often confused. Both are devices that allow simultaneous operation on 2 different frequencies, however, the DUPLEXER is a device that divides 2 frequencies in the same band and DIPLEXER is a device that divides 2 different frequency bands
