Big Performance in A Compact Shape
The new 45° Asymmetrical Horn HG4 Antenna delivers an asymmetrical beam pattern and the game-changing TwistPort™ (TP) connector in a compact form factor of the HG4 Series. Together with 30° Symmetrical Horn HG4, it is a powerful tool for optimizing and splitting traditionally designed networks with 90° sectors. The combination of 30° and 45° HG4 Horns offers flexible coverage options, high antenna gain, and class-leading noise rejection for easy and cost-effective network scalability.
Unique Asymmetrical Beam
The 45° Asymmetrical Horn HG4 features a distinctive elliptical beam shape — 45° wide in azimuth and 30° in elevation. This asymmetrical pattern is ideal for deployments where a wider azimuth and narrower elevation provide better coverage, higher gain, and optimized RF performance.
Attenuated Side Lobes
The antenna’s design naturally suppresses side lobes, focusing energy into a single main beam. The functional absence of side lobes ensures excellent noise immunity and a high Signal-to-Noise Ratio (SNR) — critical for achieving superior throughput and link stability in modern wireless networks.
Stable H + V Patterns and Gain
The 45° Asymmetrical Horn HG4 maintains stable radiation patterns across a wide frequency range. It is optimized for balanced horizontal and vertical beam patterns, a true challenge for most dual-polarized asymmetrical antennas.
Balanced H+V performance ensures consistent link quality and stable operation in all conditions. The antenna covers a 1250 MHz bandwidth (5150–6400 MHz) with highly stable gain and beam pattern.
Breakthrough Scalability
RF elements® Horn Antennas are designed for exceptional network scalability. The compact HG4 Series now includes the 45° Asymmetrical Horn HG4, perfect for dense co-location environments.
By replacing a single 90° sector with two 45° HG4 sectors, operators can increase capacity, deliver higher throughput packages, and improve service stability — all with smaller, lighter antennas.
TwistPort™ Connector
The 45° Asymmetrical Horn HG4 features our proprietary TwistPort™ connector — a quick-locking waveguide port with virtually lossless performance.
Connecting a radio is brilliantly simple: “twist and lock” — done in seconds, even with one hand.
Cross-Platform Compatibility
Wide range of TwistPort™ Adaptors allows easy integration with the most popular connectorized radios from third-party vendors such as Ubiquiti®, Cambium Networks®, Mimosa®, and MikroTik®.All coaxial cabling and connectors are enclosed and protected inside the adaptor, ensuring reliable operation and weather resistance.
HG4-CC-A45 with N connectors
The HG4-CC-A45 version comes equipped with factory-installed N-type connectors, ideal for deployments where coaxial interfaces are preferred.
Compact and Durable
45° Asymmetrical Horn Antenna are built to last and to resist harsh weather conditions.
The horn body is solid cast aluminum with a weather-resistant surface finish. The UBR bracket is made of non corrosive extruded aluminum. All hardware is made from stainless steel for long-term durability.
An ergonomic handle makes installation easy and safe. Compact, lightweight, and rugged — the HG4-A45 is engineered for effortless installation and dependable outdoor performance.
