Stein, LB3RE contacted me recently and asked if I could extend the ealier described Quadplexer circuit for use of 160/80/40m. As I already pointed out it is a modular concept. You can just remove the band you don´t need and add another one of your choice.
Here´s one idea for 160m and 80m:
series L series C coupling C
160m 14.05 uH 160 pF 800 pF
80m 7.50 uH 75 pF 430 pF
These a values based on a calculation only – I haven´t build up the filter stages for this bands myself!
Good luck Stein and whoever wants to try…
