Diplexer for HF/6M/2M
The following DIPLEXER separates the following bands HF and 6m on one side = 0 – 52 Mc – 2m and 70cm on the other side
Duplexer 144-430
Il funzionamento e' perfetto e quasi non richiede taratura
Duplexer 2m/70cm
Usare un'antenna bibanda 2/70 con due radio separate V/UHF, usare due antenne separate V/UHF con una singola radio bibanda
Wilkinson divider for 145 MHz
On 2320MHz I needed a receive power splitter for my IF 144 MHz. It had to cover the 100-150 MHz range
