Frequently Asked Questions
What is the difference between the PMAD4146 and the PMAD4145B?
Both are VHF stubby antennas for the Motorola SL series, but they cover different frequency ranges. The PMAD4146 covers 156–174 MHz, while the PMAD4145B covers 144–156 MHz. Select the antenna that matches your radio’s programmed VHF frequency range. Contact Atlantic Radio if you need help confirming the correct antenna for your deployment.
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 PMAD4146 is optimized for the SL series to balance compactness with reliable VHF performance.
Which Motorola radios are compatible with the PMAD4146?
The PMAD4146 is compatible with the Motorola SL300, SL3500e, SL500e, SL1600, and SL2600 portable radios operating in the 156–174 MHz VHF frequency range.
