RFI CRD-BNC-68 UHF Hand Portable Antenna, 450-520 MHz
RFI CRD-BNC-68 UHF Hand Portable Antenna, 450-520 MHz
RFI CRD-BNC-68 UHF Hand Portable Antenna, 450-520 MHz
Half-wave dipole design delivering a 4dB improvement over a typical 1/4 wave hand portable antenna.
Overview
The CRD-BNC-68 is a true high performance UHF hand portable antenna, specifically designed for the 450-520MHz frequency range. The CRD Series Dipoles feature a half-wave dipole design, guaranteeing reliable, clear communication in handheld applications.
The dipole element is enclosed in flexible PVC tubing for durability, and the antenna can be trimmed over the specified band using the enclosed tuning chart, allowing customisation for specific licensed frequencies.
Key Features
- 4dB improvement over a 1/4 wave whip means better range and clarity for handheld radio users.
- Half-wave dipole design means true high performance in handheld applications.
- Flexible PVC tubing enclosure means durability for everyday field use.
- Trimming capability means the antenna can be tuned to your specific licensed frequency using the enclosed chart.
- BNC(M) termination means a secure, efficient connection to compatible handheld radios.
Applications
- PMR, SMR, and trunking handheld radio applications
- Field operations requiring improved handheld antenna performance
- Two-way radios fitted with BNC(M) antenna connectors
- Replacement or upgrade antenna for stock 1/4 wave whip antennas
