Antennas RF datasheet and documents for B4505CN
Antennas RF Overview
The TE Connectivity B4505CN is a UHF whip antenna designed for mobile applications, operating within the 450MHz to 470MHz frequency range with a center frequency of 460MHz. It provides a gain of 5dBi and supports a maximum power handling capacity of 100W. The antenna features a straight whip design with a height of up to 32.250 inches (819.15mm) and utilizes an NMO base connector. It exhibits a VSWR of 2 and is rated IP67 for environmental protection.
Antennas RF Feature Summary
- Base-loaded closed coil design eliminates the need for a ground plane
- NMO base mounting interface for secure vehicle installation
- IP67 ingress protection rating for harsh environmental conditions
Antennas RF Applications
- Mobile two-way radio communications
- UHF GMRS systems
- Public safety vehicle installations
- Commercial fleet communication networks
Antennas RF Procurement Notes
Verify that the specific order includes the necessary NMO mount hardware, as it is typically sold separately from the antenna unit. Confirm the required power rating aligns with system specifications, noting the 100W maximum limit. Ensure compatibility with existing vehicle roof structures and check for any regional regulatory compliance requirements regarding the 450-470MHz band usage before finalizing procurement.
Antennas RF Selection Notes
Select this model when a ground plane is unavailable or impractical for the installation site. The base-loaded design offers a compact profile suitable for vehicles with limited clearance while maintaining effective radiation patterns. Consider the NMO base requirement for standard mounting solutions and verify that the 5dBi gain meets the desired coverage area requirements for the specific operational environment.
Antennas RF Part Context
This component belongs to the TE Connectivity B4505 series of base-loaded mobile antennas. It is engineered for reliable performance in UHF bands where traditional quarter-wave or half-wave antennas require extensive ground planes. The series focuses on providing efficient signal transmission in constrained mobile environments without compromising structural integrity or signal quality.
Antennas RF Replacement Considerations
Compatible substitutes include TE Connectivity part numbers B4505C and B4505CNS, which share identical electrical specifications and mechanical form factors.
