I have a BC355N installed in my vehicle. It is connected to a Larsen NMO/150/400/800 antenna on a NMO mount that's installed in my roof. I also have a Kenwood TK-790 radio using a 1/4 wave VHF antenna on an NMO mount that's installed about 24" in front of the scanner antenna. When I transmit with my TK-790, the scanner desenses and stops receiving until I stop transmitting unless the signal the scanner is receiving is extremely strong, in which case the signal gets all staticky. The scanner does this on both the low and high power settings (45W and 5W respectively) of my mobile. The coax for both radios runs together under the flooring of the passenger seat and up the B pillar to the roof.
I don't know why the scanner should be desensing, even at 5 watts. I thought 24" would be far enough apart as to not cause any issues. The scanner also receives very poorly on the 800 MHz band, to the point that another BC355N that I have in my apartment with back-of-set antenna receives said 800 MHz frequency better than my mobile setup. Could the scanner have a blown front end or could there be an issue with my antenna? Both radios were in my old vehicle but the antennas were even farther apart then they are now.
