Thanks mtownsend for cleaning up this thread. The negativity was out of hand.
I talked to Antennas Direct today and have decided to order a C4 Max. The weather should be nice in a few days and I should be able to get up on my roof.
I'll try to use my PC's Spectrum analyzer to see what the signals look like. Should be fun!
The good news is that C4MAX is small and that I won't have to take any of my other stuff down. In fact I think I'm going to dedicate that antenna to the rest of the house and not my home theater.
So you're using a 4-bay? My towers are approximately 10 miles closer each way.
Which 4-bay bay do you use?
Sorry, just saw this. I make my own based on MCLAPPS design. They seem to work very well for me. I have 4 or 5 around town I've made for family and friends.
