Ok scanner people I have got a antenna question for you. I have a windshield antenna from Radio Shack installed in my truck. It is mounted to the front windshield. I have been noticing that reception is well below average. Living and driving just outside of Baltimore I monitor all surronding county fire dispatch channels. I have no trouble picking up Harford county fire dispatch but I can hardly pick up nothing on the Baltimore city fire dispatch channel. Baltimore county fire dispatch channel comes in just ok. Can anyone provide me with some suggestions.
