UltraDish Directional Antenna 21dBi, TwistPort, 2-Pack | High-Gain Wideband 5.18-6.4 GHz

The RF elements UltraDish TP series consists of directional parabolic dish antennas developed for subscriber module applications. Operating across the 5180–6775 MHz frequency range, the antennas combine focused radiation patterns with minimized sidelobes and stable gain in both horizontal and vertical polarizations. These characteristics contribute to dependable wireless performance by concentrating the antenna's response in the intended direction while limiting radiation outside the main beam. The series includes versions with different gain and beamwidth characteristics, allowing the antenna to be selected according to the required directional coverage. Each version uses an aluminium reflector designed to maintain a uniform shape while keeping the antenna lightweight. The reflector and its directional characteristics form the basis of the UltraDish TP design, with both models sharing the same operating frequency range and connection system.

A key feature of the UltraDish TP series is the proprietary RF elements TwistPort waveguide interface. This quick-locking connection enables compatible wireless devices to be attached or replaced without changing the antenna itself. Both antenna versions work with any TwistPort Adapter, allowing the same connection principle to be used with different supported radio configurations. Rather than relying on a conventional coaxial antenna connection, the TwistPort interface connects compatible equipment through a waveguide port. This arrangement is particularly useful when a wireless device needs to be replaced while retaining the installed dish antenna and its mounting position.

The UltraDish TP series is equipped with a substantial mounting system designed for secure attachment and directional adjustment outdoors. The improved grip accommodates poles with diameters ranging from 40 to 80 mm, with RF elements recommending a diameter as close to 80 mm as possible. This mounting range allows the same installation arrangement to be used with both antenna versions. The mount provides angular adjustment for directing the parabolic reflector toward the intended wireless connection, making antenna positioning an integral part of installation. Its construction combines a firm attachment to the mounting pole with the ability to adjust the direction of the reflector. Stainless steel mounting hardware has a black coating intended to prevent seizing during installation, helping the fastening components remain suitable for adjustment while the antenna is being mounted.

Both UltraDish TP versions use UV-resistant ABS plastic, polycarbonate, aluminium, and stainless steel in their construction. They carry an IP65 protection rating and operate at temperatures from −40 °C to +60 °C, making them suitable for outdoor environments within these conditions. The antennas are rated to withstand wind speeds of up to 160 km/h, an important consideration when selecting exposed mounting positions. Although the two versions differ in reflector dimensions and wind loading, they share the same environmental protection and mounting principles. This makes it possible to select the appropriate directional antenna while retaining a consistent approach to installation, fastening, and outdoor operation across the UltraDish TP series.
