Best Band pass filter for 800 mhz interfrence from cell tower

[EasternMassScanFan]

Looking for the best band pass filter to use on my BCD325P2 and the SDS100. I have a pretty common issue when I get within less than 1/2 a mile from a cell tower, the reception of the 800mhz analog system drops completely. Just wondering what are the best band pass filters for 800mhz that will block out cell interference.
