VHF Stubby Antenna for SL3500e (156–174 MHz, 5 cm)

The Motorola PMAD4146B is a genuine VHF stubby antenna designed for compatible MOTOTRBO slim portable radios operating between 156 and 174 MHz. Its compact 5 cm profile helps preserve the radio’s lightweight, discreet design while providing dependable performance within the correct VHF frequency range.

This low-profile antenna is ideal for hospitality, retail, education and security professionals who want to minimize antenna bulk. Its short design is less likely to catch on clothing or nearby equipment than a traditional full-length whip antenna.

The PMAD4146B is specifically tuned for the upper portion of the VHF band. Always verify the radio model and programmed operating frequency before ordering, as other antenna versions are required for lower VHF frequencies.

Stubby Antenna Benefits

The compact 5 cm design helps maintain the slim profile of compatible Motorola radios. It is an excellent choice for users who prioritize comfort, discretion and freedom of movement during everyday operations.

A stubby antenna may not provide the same fringe-area performance as a properly matched full-length whip antenna. Actual communication range depends on terrain, buildings, radio power and system configuration.

Important Frequency Information

The PMAD4146B is designed specifically for VHF radios operating within the 156–174 MHz frequency range.

For radios using other VHF frequencies, select the appropriate antenna:

• PMAD4144: 136–144 MHz

• PMAD4145: 144–156 MHz

• PMAD4146: 156–174 MHz

Using an antenna outside the radio’s programmed frequency range may reduce communication performance.

Ideal Applications

• Hotels and hospitality

• Retail stores

• Schools and campuses

• Healthcare facilities

• Event management

• Security operations

• Restaurants and entertainment venues

• Replacement of a damaged or missing antenna
