Omnidirectional broadband UHF dipole binary array, aluminium, 400-520 MHz, 250W, 4.3-10 female, dual 0.5m cables, 40dB isolation between halves, 2 x 3dBd - 4.6m

The DUA-4052AL-ISL-6-2 omnidirectional broadband UHF dipole binary array antenna is engineered for 400-520 MHz applications requiring consistent coverage, high reliability, and interference mitigation. Constructed from durable aluminium and measuring 4.6 m, this antenna delivers 3 dBd gain per half with dual 500 mm cable tails and 4.3-10 female connectors, supporting transmit power up to 500 W per input. Its true omnidirectional radiation pattern ensures uniform coverage in all directions, making it ideal for towers, rooftops, and high-mounted structures where full 360° signal propagation is required.

A key feature of the DUA-4052AL-ISL-6-2 is the 40 dB isolation between its dual halves. This high level of electrical isolation minimises cross-coupling and mutual interference, ensuring that signals from each half remain clean and independent. The result is improved signal clarity, lower intermodulation distortion, and more predictable performance in dense RF environments. This makes the antenna particularly valuable for critical communications, government radio networks, distributed antenna systems, and other applications where maintaining signal integrity across multiple feed lines is essential.

With a fully welded aluminium frame and broadband dipole design, the DUA-4052AL-ISL-6-2 combines mechanical robustness with exceptional electromagnetic performance. Its design enables flexible installation in dual-feed or array configurations, and the low PIM characteristics of its coaxial internals ensure reliable operation in high-power, high-density deployments.

Optimised for professional RF networks, broadband UHF coverage, and interference-critical applications, the DUA-4052AL-ISL-6-2 provides engineers with a durable, high-performance solution for omnidirectional UHF deployment.
