Pinellas system
That kinda helps my situation, i am using a pro-668 and the only way i can get great reception on this system is if i go out on my porch. The weird thing is i am only about 8 miles from the closest tower ( E lake) from me but it appears not all the frequencies are transmitting from that tower and instead are coming from the Tarpon tower which is further away. so some of the frequencies will not decode and others sound flawless. The system design is interesting at that.
The reason i ask is I was wondering if the Unidens do any better on the system but it appears not. I am using a radio shack 800 mhz rubber ducky, a professional motorola 800 mhz rubber ducky and the telescoping antenna. Surprisingly i get best results with the telescoping antenna.
