VHF/UHF Antennas R&S®HK055S1 Omnidirectional Broadband Antenna R&S®HK055S1 Omnidirectional Broadband Antenna 27.5 MHz to 600 MHz Compact transmitting/receiving antenna especially designed for operation on board ships The R&S®HK055S1 omnidirectional broadband antenna covers the extremely wide frequency range from 27.5 MHz to 600 MHz. It is designed for stationary transmission and reception and can be used for many types of communications and for monitoring tasks. The antenna features outstanding characteristics; no tuning equipment is required, making it ideal for hopping and for multichannel operation. Key facts ❙ ❙ ❙ ❙ Extremely wide frequency range Compact dimensions High efficiency Rugged design especially for rough handling on board ships ❙ Wide operating temperature range ❙ Especially suitable for multiband, multimode, multirole radios (MMRs) Rohde & Schwarz HF – VHF/UHF – SHF Antennas | Catalog 2014/2015 Antennas2014_2015_cat_en_0758-0368-42_v0700.indb 104 04.06.2014 09:56:36 VHF/UHF Antennas R&S®HK055S1 Omnidirectional Broadband Antenna 10 kHz 1.5 10 100 MHz 10 18 1 1.3 GHz 26.5 1 40 2 Specifications Frequency range 27.5 MHz to 600 MHz Polarization vertical Input impedance 50 Ω VSWR < 3.0 (measured on a 3 m × 3 m ground plane) Gain Elevation pattern < 110 MHz monopole-like > 110 MHz dipole-like 3 Input power max. 100 W CW (≥ 30 MHz), max. 50 W CW (< 30 MHz) Connector N female 27.5 MHz to 110 MHz –1 dBi to +2 dBi (typ.)
