Product Description
TE Connectivity B4505CS UHF NMO Mobile Antenna with Spring - 450-470 MHz
The TE Connectivity B4505CS is a commercial UHF mobile whip antenna designed for 450-470 MHz vehicular radio installations. This chrome-finish antenna combines a closed-coil collinear design, 5 dBi gain, an NMO interface, and an integrated spring for mobile installations exposed to vibration and movement.
Designed for professional land-mobile-radio applications, the B4505CS provides an omnidirectional radiation pattern and is suited to fleet vehicles, municipal operations, industrial vehicles, service fleets, and other commercial UHF radio systems operating within its specified frequency range.

Commercial UHF Mobile Antenna for Vehicle Radio Systems
The B4505CS is designed for professional mobile communications systems operating from 450 to 470 MHz. Its omnidirectional pattern provides coverage around the vehicle, making it suitable for mobile radios used by field personnel, fleet operators, public-service organizations, industrial teams, and other organizations that rely on vehicle-mounted UHF communications.
An integrated spring helps accommodate vibration and mechanical movement encountered in mobile installations. The antenna uses the widely adopted NMO mounting interface, allowing it to be installed with a compatible NMO mount and coaxial cable assembly.
Ideal Applications
- Commercial two-way radio vehicle installations
- Municipal and public-service vehicles
- Industrial and maintenance fleets
- Utility and service vehicles
- Security and facilities vehicles
- Transportation and logistics fleets
- Other 450-470 MHz UHF land-mobile-radio systems

Frequently Asked Questions
What frequency range does the B4505CS cover?The B4505CS is designed for operation from 450 to 470 MHz in the UHF band.
What is the gain of the B4505CS?The antenna is rated for 5 dBi gain.
Does the B4505CS use an NMO mount?Yes. The B4505CS uses an NMO antenna interface and should be installed on a compatible NMO mounting system.
Does the antenna have a spring?Yes. The B4505CS is the spring-equipped version of the 450-470 MHz closed-coil collinear antenna.
Is this antenna omnidirectional?Yes. It uses an omnidirectional radiation pattern for coverage around a properly installed mobile radio system.
How long is the B4505CS?TE Connectivity's mobile load coil datasheet specifies an overall length of approximately 94.0 cm (37.0 inches).
Is an NMO mount included?An NMO mount should not be assumed to be included. Select a compatible mount separately unless your vehicle already has the appropriate NMO installation.
Will the B4505CS work with my mobile radio?It may be suitable when your radio system operates within 450-470 MHz and uses a compatible 50-ohm NMO antenna installation. Confirm your radio frequency and mounting requirements before ordering.
