With malice toward none, I am going to repeat that in the real world people are doing this with these Force-12s with excellent results. How does that quote about modeling go? Too much and it begins t
That's correct. If you use enough filtering you can run it all through one coax!! By itself a few feet of separation doesn't mean much. 73 Tom _______________________________________________ _______
Modeling a system like this is very complicated since the input impedance of the radio on receive and the output impedance of the PA stage on transmit when looking back into the PA sets the load on
It would be somewhat challenging to model (although an interesting problem for a class).. Most filters don't present a very good match outside their passband, reflecting almost all the power (but who
The problem is every system is very different. The feedline length and type and even the equipment affects what you can get away with. Stubs are not perfect shorts or perfect opens at resonance (the

That is pretty incredible. What kind of filtering did you use? We used this antenna in this way Multi-Two with no problems at HP1XX in ARRL DX CW. However, we took rather extreme measures using combi
I received a note from Bob today saying that he uses three different feedlines from his C-31XR for SO2R and also throws into the mix his 2el 40m Yagi that you can see on his tower. He says it all wor
