Single and Dual Isolators for the 150 MHz Band
Description
  • Medium power single or dual isolators for 145 – 175 MHz.
  • Used to isolate / protect of transmitters.
  • High frequency stability on temperature and power.
  • The standard 15 W dummy load can easily be interchanged to other values, if the reverse power is expected to exceed 15 W.
  • Tunable within the frequency range.
  • The isolators have black coating to prevent corrosion.
