The RF Elements UltraDish TP 21 (2-pack) in depth

What it is

UltraDish TP is RF Elements' parabolic dish family with the TwistPort connector. The 21 model gives 21.2 dBi from a 465 x 345 mm reflector and is aimed at subscriber links, but works equally as one end of a point-to-point link. RF Elements ships it in packs of two.

TwistPort

TwistPort is RF Elements' quick-locking waveguide port: the radio clicks onto the antenna with no RF cables, so a radio can be swapped in seconds. TwistPort adaptors are available for popular Ubiquiti, Cambium, MikroTik and Mimosa radios, and an RP-SMA adaptor covers connectorised radios.

Noise rejection

A 28 dB minimum front-to-back ratio and suppressed side lobes mean the dish hears less of the interference behind and beside it, which keeps modulation up on busy towers and in dense neighbourhoods.

Availability

RF Elements lists the UltraDish TP range among its recently discontinued products. We sell remaining Australian stock while it lasts.
