Description

The RF Elements UltraDish™ TP 21 is a high-performance parabolic antenna designed for operators who demand reliability and efficiency in wireless networks. Engineered with a 21 dBi gain, it provides long-range, highly directional connectivity, making it ideal for point-to-point (PtP) links, customer premises equipment (CPE), or backhaul applications.

Its TwistPort™ waveguide connector ensures virtually lossless radio connection, reducing RF losses and simplifying installation. The antenna’s compact 21 dBi form factor combines strong gain with easier handling and less wind load compared to larger parabolic antennas. This allows ISPs and WISPs to achieve stable performance even in challenging deployment conditions.

The UltraDish TP 21 features a rugged, weather-resistant design built to withstand outdoor conditions year-round. Its predictable beam shape, excellent side-lobe suppression, and cross-polarization performance minimize interference, ensuring consistent throughput and network stability.

Supplied in a 2-Pack, it provides excellent value for operators rolling out multiple links, making it a practical solution for building reliable, long-distance wireless infrastructure.
