Are there any filters out there that can be used to eliminate cell tower interference?
I mostly monitor re-banded trunk systems between 851 - 860 mhz. Almost every time I drive near a tower, an otherwise strong signal turns to varying degrees of crap, from making the audio scratchy to very distorted to the loss of signal entirely... until I get 1/4 to 1/2 mile away.
I would love to have one antenna set up with an in-line filter that only allows the 851 - 860 mhz band through while rejecting everything else. And have a second antenna set up normally with both going to a switch. When I encounter the tower problem on the un-filtered antenna, I could switch over to the filtered line and get some relief.
Is this possible? If so, where can I get that filter?
