I was going through HDTVPrimer.
When I noticed a mod for the CM3671 using separate leads.
There appears to have been a noticeable difference gain.
I am considering removing the board and replacing it with 2 older Channel Master baluns.
Run 2 preamps and then combine in the house behind the power sources.
Has anybody done attempted something similar.
