Hi! I need some input. I'm not to the BCFY feed that I set up. I had a small antenna on top of the roof and the feed broadcasted fine. Nice and clear. Today, we installed a large 5 foot antenna outside and now, my feed is nothing but loud humming and anything that comes through on the scanner (Super clear by the way), is garbled on the feed. I did order an isolator but I'm really not sure if that's the issue. The only thing different is the antenna. Any thoughts or suggestions are welcome! Thanks!!
