VHF/UHF Antennas R&S®HF902 Omnidirectional Antenna

56 Rohde & Schwarz HF – VHF/UHF – SHF Antennas | Catalog 2017/2018

The R&S®HF902 omnidirectional antenna has been de-signed for the reception of vertically and horizontally polar-ized waves. It is ideal for broadband detection and moni-toring of RF signals in the frequency range from 1 GHz to 3 GHz.

With a diameter of only 0.31 m and a height of 0.49 m, the compact broadband antenna is particularly suitable for applications where the available space is limited.

A compact omnidirectional receiving system for horizon-tally and vertically polarized waves in the frequency range from 20 MHz to 3 GHz is obtained when combining the R&S®HF902 with the R&S®HE309E, R&S®HE314A1 and R&S®HF214 antennas.

Key facts ❙ Broadband frequency range ❙ Easy integration into broadband antenna systems due to cable feedthrough

❙ Compact ❙ Rugged design ❙ Suitable for mobile use ❙ Ideal for detection and monitoring of horizontally and vertically polarized signals
