RF Elements UltraDish TP-21 2Pack




UltraDish™ TP 21 is designed for subscriber module applications. Minimized sidelobes, wide frequency bandwidth, and stable gain in both polarizations assure dependable performance. Antenna reflector is made of aluminium to ensure a low weight and uniform shape. Our proprietary TwistPort™ waveguide connector enables intuitive radio connection and replacement. Massive mount with improved grip and a wide range of applicable pole diameters makes the deployment easy and versatile. Stainless hardware comes with black coating to prevent from seizing at the installation.

  • High Gain Directional Antennas 
    • UltraDishTM TP Antennas are parabolic dish antennas with a wide gain range and lossless TwistPortTM connector. The UltraDish TP Antennas have high directivity and suppressed side lobes for the ultimate performance.
  • Beam Performance 
    • The radiation pattern of UltraDishTM TP Antennas with suppressed side lobes minimizes the collected and transmitted interference in high-noise areas. The flexible gain of UltraDishTM TP Antennas is achieved by adjusting the size of the main reflector size that focuses the signal fed via the TwistPortTM connector.
  • Ultra-Wideband Performance in 5 and 6 GHz 
    • Stable antenna gain is important for reliable link performance. The gain of all three UltraDishTM TP Antennas is stable in the ultra-wideband spectrum: 5180-6775 MHz, letting you leverage the extremely wide band with reliable link performance.
  • TwistPortTM Connector 
    • TwistPortTM is our patent-pending quick-locking waveguide connector with practically zero loss. It connects our antennas to an RF radio and embodies the new standard for scalable, high-performance, and easy-to-use wireless equipment.
  • Easy Connection 
    • TwistPortTM operation is extremely easy. The mounting and RF connection of the radio is combined into a single, elegant, and highly functional "twist and lock" design. A single-handed radio installation is now a real option!
  • Lossless 
    • TwistPortTM connector is practically lossless. With no coaxial connectors or cables, there is no loss introduced during the delivery of the signal from the radio to an antenna. The ultra-low loss of waveguide makes TwistPortTM losses practically unmeasurable.
