Coupleurs antennas for 2,4,6
The 1/4 wave of adaptation is calculated = Zo = root of Z1 x Z2 i.e. Zo = root of 50 x 100 = 70.7 ohm , D / d = 3.1 on the abacus formula corrected for the square section example: D = 20 mm and d = 6.5 mm

Proyecto de duplexor para VHF-UHF
A duplexer you needed to be able to use the two directional antennas on your single-connector equipment
Six Meter Heliax Duplexer Construction
I have begun to construct the second generation 6 Meter Duplexer based upon the lessons that I have learned by experience
SDR Diplexer
2 antenne al mio ricevitore SDR Sdrplay RSP1A mi ha fatto progettare il seguente diplexer
Splitter per HF
Se fornisco a due ricevitori il segnale captato da un’antenna attraverso un coassiale a 50 Ohm per tramite di un connettore a T, capiteranno delle cose strane, spesso prevedibili
Splitter Distribution of a HF signal on two receivers, DH1TW
Lately I needed a 3dB splitter for a HF 1-30MHz measurement project. Instead of buying me a splitter, I decided to build it on my own
