Broadband Mobile Antenna
Key facts 27.5 MHz to 600 MHz Compact transmitting/receiving antenna specially designed for operation on board vehicles The Broadband Mobile Antenna R&S®HK055L1 covers the extremely wide frequency range from 27.5 MHz to 600 MHz. It is designed for mobile transmission and reception in connection with MMRs. 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. The antenna is equipped with a spring at its base. If the antenna strikes an obstacle, it will bend and automatically return to its vertical position.
features & benefits
  • Extremely wide frequency range
  • Compact dimensions
  • High efficiency
  • Rugged design especially for rough handling onboard vehicles
  • Wide operating temperature range
  • Especially suitable for multiband multirole radios (MMRs)
