The Y304 from ZCG Scalar is a precision-engineered VHF 4 element Yagi antenna designed for reliable, high-efficiency performance across the 100-250 MHz VHF frequency range, with tuning optimised to a specified 4% bandwidth for accurate system alignment. This targeted design approach ensures strong electrical performance, making it ideal for applications where frequency precision, signal clarity, and directional control are critical.
Built from durable aluminium construction, the Y304 offers a lightweight yet rigid structure suited to long-term outdoor deployment across communications infrastructure, defence systems, telemetry networks, and VHF radio installations. Its 4-element directional array delivers a balanced 7.5 dBd gain, providing effective forward signal concentration and improved front-to-back ratio performance for point-to-point links and interference rejection.

With a 250W power handling capability, the Y304 supports continuous-duty operation in demanding RF environments. It is fitted with an N-type female connector and includes a 1.4 metre integrated cable tail, allowing for straightforward integration into professional RF systems while maintaining low feedline losses. The antenna?s 2.3 metre boom length supports stable radiation characteristics while remaining practical for installation on towers, masts, and elevated structures.
Designed for fixed installation, the Y304 is best deployed at height to maximise coverage and link efficiency, making it well suited to base station infrastructure, remote communications sites, and network backhaul applications. Assembly is simple and can be completed on-site using basic tools, supporting efficient deployment in field conditions.
As part of the ZCG Scalar directional antenna range, the Y304 provides a robust and highly accurate VHF Yagi antenna solution, delivering dependable performance, precise tuning capability, and long-term durability for professional RF communication systems.
