For all my south jersey listeners, what would be a good antenna to use on my psr 500 to monitor this system? I am mobile and change vehicles daily so I need something portable. I have asked for tips to tweak my radio in the past and was offered no help. Maybe a good antenna will help improve my reception. I have both A&C in seperate scanlist and have the unit set to multi site. I use the win 500 software to program my unit. I also have the radio shack rubber duck 800mhz antenna in use and helps a little over the stock antenna. I want to say thank you in advance for all tips.
