Manufactured in Australia, the CT400 is a purpose-built low-profile ground dependent UHF antenna designed for reliable performance across the 400-500 MHz UHF band, making it ideal for fleet communications, transport infrastructure, rail, mining, and industrial installations where antenna height must be minimised.
Engineered in a rugged low-profile form factor, the CT400 is specifically designed for environments where traditional whip antennas are vulnerable to impact, vandalism, or physical obstruction, such as vehicle roofs, public transport, and heavy equipment. Its compact 230mm footprint allows for discreet installation while maintaining stable RF performance in demanding operational conditions.

Engineered in a rugged low-profile form factor, the CT400 is specifically designed for environments where traditional whip antennas are vulnerable to impact, vandalism, or physical obstruction, such as vehicle roofs, public transport, and heavy equipment. Its compact 230mm footprint allows for discreet installation while maintaining stable RF performance in demanding operational conditions.
Unlike ground independent designs, the CT400 operates as a ground dependent antenna system, utilising the mounting surface as part of its RF performance structure. When correctly installed, it delivers a consistent 2.1 dBi gain, providing balanced omnidirectional coverage suitable for UHF voice and data communication systems operating within its specified frequency bands.
With a 100W power handling capability, the antenna is suitable for standard and higher-power UHF radio systems used in commercial and infrastructure networks. It is fitted with an N-type female connector, ensuring secure RF integration and compatibility with professional-grade coaxial feed systems.
Installation is mechanically straightforward, requiring four 6mm mounting holes, and the antenna is supplied with M6 x 20mm set screws to ensure secure and stable attachment to the mounting surface, the unit will also require a suitable hole for the N-type female pass-through. This design supports long-term durability in high-vibration and high-traffic environments.
As part of the ZCG Scalar low-profile antenna range, the CT400 provides a robust UHF transit-style antenna solution, designed for applications where low visibility, mechanical protection, and dependable RF performance are equally critical.
