“The ZCG Scalar RA4-R Broadband UHF Corner Reflector Antenna is designed to deliver reliable, high-gain directional performance across the 410-510 MHz frequency range. Built for professional communications and high-demand RF environments, this antenna combines broadband capability with a robust construction to ensure consistent signal performance and long-term durability in outdoor installations.
Featuring a welded open grid aluminium reflector, the RA4-R provides excellent structural strength while reducing wind loading, making it well suited for tower, mast, and rooftop deployments. The corner reflector design focuses RF energy into a controlled directional beam, improving signal coverage and link reliability while helping reduce interference from unwanted directions. With a gain of 10 dBd, the antenna enhances both transmission and reception performance across the UHF band.

With a gain of 10 dBd, the antenna enhances both transmission and reception performance across the UHF band.
The RA4-R is engineered with low Passive Intermodulation (PIM) characteristics, achieving greater than -150 dBc performance (@ 2 x 20W) to support modern multi-channel communication systems where signal clarity is critical. This makes it an ideal choice for professional radio networks, public safety infrastructure, and other applications where maintaining clean RF signals is essential.
Supporting up to 500 watts of power handling, the antenna is fitted with a high-quality 4.3-10 female connector to ensure secure, low-loss connectivity and dependable RF performance. Its broadband design allows flexible deployment across the 410-510 MHz range, supporting a variety of UHF communication systems without the need for multiple antenna types.
Measuring 750 mm by 750 mm, the RA4-R provides a balanced combination of compact size and strong directional performance. Built for reliability, durability, and low PIM operation, the ZCG Scalar RA4-R Broadband UHF Corner Reflector Antenna is a dependable solution for organisations requiring stable, high-quality UHF communications.”
