Frequently Asked Questions
What is the difference between PMAD4144, PMAD4144A, and PMAD4144B?
The PMAD4144, PMAD4144A, and PMAD4144B all refer to the same VHF stubby antenna. The letter suffix indicates a factory revision. All versions are functionally identical and compatible with the same Motorola SL300 and SL3500e radios.
Why choose a stubby antenna over a standard whip?
At 5 cm, the PMAD4144 is significantly shorter than a standard whip antenna. This makes it ideal for belt-worn use, reducing the risk of the antenna snagging on clothing or equipment and improving comfort during long shifts. Trade-off: stubby antennas typically have a slightly shorter effective range than full-length whip antennas.
Which Motorola radios are compatible with the PMAD4144?
The PMAD4144 is compatible with the Motorola SL300 and SL3500e portable radios operating in the 136–144 MHz VHF frequency range.
