Frequently Asked Questions
What is the difference between a stubby antenna and a standard whip antenna?
A stubby antenna is significantly shorter than a standard whip antenna, providing a lower-profile form factor that is less obtrusive during belt-worn use. The trade-off is a modest reduction in range compared to a full-length whip. The PMAD4145B is optimized for the SL300 and SL3500e to balance compactness with reliable VHF performance.
Is the PMAD4145B the same as the PMAD4145?
Yes. The PMAD4145B is the current revision of the PMAD4145. Both part numbers refer to the same VHF stubby antenna for the SL300 and SL3500e.
Which Motorola radios are compatible with the PMAD4145B?
The PMAD4145B is compatible with the Motorola SL300 and SL3500e portable radios operating in the 144–156 MHz VHF frequency range.
