So I’ve been testing both the original purple band and new blue band “gain” antenna for the Unication G4/5 pagers. The following Motorola and Harris P25 systems and subsequent sites were used:
Palm Beach County
-Countywide Simulcast
-Delray Beach
-Boynton Beach
West Palm Beach
PSIC
Broward County
-Coral Springs
-Plantation
-Fort Lauderdale
Miami-Dade County
Additional equipment used along with the G5 as a signal comparison:
APX8000 (2), APX6000 and XTS5000.
Results:
The new blue band “gain” antenna is “slightly” better. What do I mean by that....well, from what I’ve noticed with trunked systems...when you have a good signal, you have a good signal.
With the Countywide simulcast trunked systems being built so well with so many sites blanketing the coverage area, it’s not really a distinguishable difference.
I’d say about maybe a 1/2 signal bar difference. In other words, if I have 3 bars and it flickers to full 4, with the new antenna that flicker to 4 became a solid 4. But if I have a solid 3, I’m still a solid 3. If I’m OOR, I’m still OOR. So if you are on the fringe I think you will still be on the fringe. You may not go OOR as quickly, but if the signal is not there, it’s not there with either antenna. The dBm is slightly less with the newer antenna and getting less frame errors, but I’m talking only -3 to -5 dBM.
