Wideband Antenna Benefits

The PMAD4147A covers the complete 136–174 MHz VHF band, reducing the need to stock separate antennas for narrower VHF frequency segments. This makes it especially useful for mixed radio fleets and organizations operating on multiple licensed VHF frequencies.

Range and Performance

The full-length flexible whip design can provide improved communication range compared with a compact stubby antenna, particularly in rural areas, outdoor environments or fringe coverage locations.

Actual range depends on terrain, buildings, radio power, system configuration, antenna placement and operating frequency.

GPS Information

The PMAD4147A supports GPS reception when installed on a compatible GPS-equipped Motorola radio. It will not add GPS functionality to a radio that does not already contain the necessary GPS hardware, software and programming.

Important Frequency Information

The PMAD4147A is designed specifically for VHF radios operating within the 136–174 MHz frequency range. It is not compatible with UHF, 700/800 MHz or 900 MHz radio configurations.

Verify your radio model and operating frequencies before purchasing.
