Compact 380–520MHz UHF Antenna for APX N-Series Portables
The Motorola AN000451A01 is a 90mm UHF stubby antenna with a ferrule mounting style for compatible APX N-series portable radios. Its short profile offers a compact alternative to a longer antenna when wearing a radio on a belt or chest rig.

Frequently Asked Questions
What frequencies does AN000451A01 cover?
The listed antenna range is 380–520MHz UHF. Your radio hardware and programmed channels must also support the frequencies you intend to use.
How long is this antenna?
It measures 90mm, or 9cm, and uses a compact stubby design.
When should I choose a stubby antenna instead of a longer antenna?
Choose a stubby when a shorter carry profile is a priority. Actual coverage depends on the radio, antenna, operating frequency, terrain and system design. This listing does not guarantee equal or greater range than a longer antenna.
Does this antenna include GPS?
No. AN000451A01 is listed without an integrated GPS element. Check your radio's antenna requirements if GPS functionality is needed.
Will it fit any APX N-series radio?
APX N30, N50, N70 and N70XE are the retained compatibility references. Confirm the specific radio's UHF band and matching ferrule antenna interface before ordering.
Can I use this antenna on an XPR or older APX radio?
Those radios are not established as compatible by this listing. Select an antenna approved for the exact radio model, frequency band and mounting interface rather than assuming interchangeability.
Does this antenna work on VHF or 700/800MHz channels?
This is a 380–520MHz UHF antenna. Select the appropriate band-specific antenna for channels outside that range.
Are a radio, battery or microphone included?
No. This listing is for the AN000451A01 antenna. Radios, batteries and microphones are separate purchases.
