I have purchased a SDS200 scanner. I've been listening with Uniden 996P2. With the back of the radio antenna, the range is somewhat limited with the 996Ps. I thought the SDS200 would be a better broadcast. I disconnected my other scanner and use an outdoor wideband antenna. It comes in better. I was thinking on purchasing a dedicated antenna just for 7-900 mhz. I've tried changing the filter settings on the SDS200 and feel that normal wide band sounds the best. Am I missing something or would a dedicated antenna correct my problem? Some transmissions sound a little like sideband isn't adjusted perfectly. I have a lot of simulcast in central Mass. I am trying to hear the Mass State Police. Does anyone have suggestions?
