Scanner Master lists three different 800MHz Band Pass Filters on their site. There are no specs shown of any kind. There is no explanation for the suffix on the part numbers. I guess one can assume EN = Extra Narrow, N = Narrow, and W= Wide? Does anyone have any additional information on these? What is the actual difference between them? Is anyone actually using any of these and how have they impacted monitoring the public service comms in the 800MHz spectrum and do they attenuate desired signals in the 700MHz spectrum, which is in use these days? I'm thinking they would not be very effective in eliminating interference from the cellular band as it is also in the same spectrum. Yet I do recall a recent post (about a month ago) where someone was claiming they did help in reducing interference from cell towers.
