Tripleo,
You said no new ideas but you did give me some ideas. Today is supposed to be a nice day today and I want to get some progress done.
I'm trying to gather enough knowledge and yours is very helpful. You mentioned wider directors helps out with the low end of the hi VHF band. I have wider directors from the two donor reflectors. I could use those towards the back.
First thing I want to do his do some baseline testing with what I have. I have two project antennas I could modify one I'll make it a little bit longer with more directors compare that to my original.
I've got to come up with a plan first though. I'll post my findings here.
I also plan to test my new lossless combiner! I'm kind of excited about that. Thanks to Calaveras over on AVS for the idea.
