PRODUCT OVERVIEW
This chapter gives a general description of the RB31 system.
Introduction to RB31
Vaisala Telemetry Antenna RB31 is a directional UHF antenna used
with the Vaisala DigiCORA® Sounding System to receive radiosonde
signals in the 400 MHz meteorological band.
RB31 can be used in conjunction with the Vaisala DigiCORA®
equipped with Vaisala Sounding Processing Subsystem SPS311.
The main idea when planning the antenna arrangement was to obtain a
radiation pattern providing a good signal during sounding under any
wind conditions.
RB31 is well-suited for use in fixed installations. The antenna has no
moving parts; the radiation pattern of the antenna can be electrically
directed to track the flying radiosonde.
