Compact transmitting/receiving antenna especially designed for operation on board ships

The Omnidirectional Broadband Antenna R&S®HK055S1 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 in many areas of communications as well as for monitoring tasks. The antenna attains its outstanding characteristics without the use of any tuning equipment.


It is therefore ideally suited for hopping but also for multichannel operation.
