Maybe a list and direction of what you want. Such as NE .... and SE....
I'm going to do some testing with this to strengthen some backside channels. Then I'll use another one sometime and try some Tropo with channel cut/amp/antennas.
You could cascade a pair of these with the weaker stations on the first combiner.
should have mentioned he can custom build so the extra inputs could have more than one channel on them. Might take a few weeks to make and get around the world to you.
