I get varying results with my BCD436HP using the stock antenna. I am in the Blue Ash area weekly. When I stay at the Hampton Inn (4th floor NE corner) on Creek Rd between Reed Hartman and Kenwood (behind the Blue Ash FD) I have great reception - truly zero issues. Once I stayed at a hotel near Cornell/Kenwood (5th floor SE corner) and reception (simulcast distortion) was horrible, nearly unusable. I was able to move around in the room, found select locations with slightly better performance.
My experience can be summarized by stating location, location, location.
