La description

For connecting a broadband antenna to transceivers with multiple VHF and UHF ports
Key facts 27.5 MHz to 88 MHz (108) 118 MHz to 174 MHz 225 MHz to 550 MHz For connecting a broadband antenna to transceivers with separate VHF and UHF outputs The R&S®FT255 Triplexer allows the connection of a broadband antenna (e.g. R&S®HK055L1, R&S®HK055S1 or R&S®HK061) to transceivers with separate VHF and UHF outputs or to up to three separate VHF/UHF transceivers.
features & benefits
  • Combined Lowpass and Highpass concept
  • Low insertion loss
  • High isolation
  • Good impedance match
  • Compact design
  • Versatile application
