Horn antenna RF Elements UD-TP-21

The Horn antenna RF Elements UD-TP-21 is a compact high-performance horn antenna tuned for the 5.18–6.4 GHz band. Featuring a measured gain of 21.2 dBi and a TwistPort-compatible feed, the UltraDish™ TP 21 provides a focused radiation pattern for point-to-point and short-range point-to-multipoint links. Its molded radome in white and compact footprint (475 mm × 395 mm × 170 mm) make it suitable for installations where space, wind loading and visual impact are considerations.

Advantages

The UD-TP-21 delivers predictable antenna patterns and stable gain across the specified frequency range, reducing interference and improving link margin. The integrated TwistPort interface simplifies connection to compatible radio heads and radios without complex adapters. A compact form factor and durable radome lower wind load and ease mounting, while the horn design offers controlled sidelobe behaviour for cleaner links in dense deployments.

Suitable for

• Short- to medium-range point-to-point links in the 5.18–6.4 GHz band
• Point-to-multipoint sectors where a focused beam is required
• Outdoor wireless backhaul and last-mile connectivity
• Environments that require low visual profile and reduced wind load

Key specifications

• Frequency range: 5.18–6.4 GHz
• Peak gain: 21.2 dBi
• Connector/interface: TwistPort-compatible feed
• Polarization: linear (dependent on connected radio)
• Radome colour and material: white molded radome
• Dimensions (W×D×H): 475 mm × 395 mm × 170 mm
• Typical use: outdoor fixed wireless links and sector applications

How to use

Mount the antenna on an appropriate mast or tower using compatible mounting hardware, ensuring secure attachment and correct orientation toward the intended remote site. Attach a TwistPort-compatible radio or feed assembly directly to the horn feed, following the radio manufacturer’s mechanical alignment and grounding instructions. Verify polarization alignment with the remote antenna and perform a link test to confirm signal levels and alignment before finalizing the installation.

Usage recommendations

Position the UD-TP-21 to maintain a clear line-of-sight to the remote endpoint and allow margin for seasonal foliage or refraction. Use proper grounding and lightning protection as part of the outdoor installation. For best performance in dense deployments, verify antenna azimuth and downtilt to minimize interference and optimize throughput.
