Here is my analysis, I am replacing an ancient UHF bowtie and so far have installed a CM 4221hd and it is aimed South. My old install had a Radio Shack pre-amp that had 300ohm connections so the mast mount transmitter won't work with my new antenna. I still have the inline amp hooked up that went with that and further down the line I have a Radio Shack distribution amp. There is about 100' of coax overall to the tv. The antenna is about 20' high.
The stations come in pretty good except 11.1 and 11.2 are probably the worst and often won't come in at all, 42.1 and 42.2 are next worse. I was planning to get another pre-amp but don't know what would be the best. If I take the old amp from the pre-amp out of the line I lose just about everything.
Thanks in advance for any help, hope I gave enough info to help.
