  Test set A/VHF PRG 70

This set is used to check and find faults in the antenna system of the following radio sets:

  • SEM 70, SEM 80, SEM 90, SEM 93
  • Sem 52-S and SEM 52-S/Fz
  • SEM-52-SL-H and SEM-52-S.

    It consists of:

  • suitcase with detachable lid,
  • PRG-70 - insert
  • 2 BNC- cables 1,2m
  • 1 BNC- connectors
  • 1 adapter SBZ / BNC
  • 1 antenna replica SEM 70

    The set measures:

  • TX power in 4 ranges: 1, 4, 10, 40 W
  • reverse running power in % (only at 4 and 40 W)
  • locking voltage -50 V for the NEMP- protecting diodes in the antenna base FAF 80.

  • The antenna replica SEM 70
       transforms the complex resistance of the SEM 70's antenna output to the 50 Ohm of
       the PRG 70.

  • A substitute load of 50 Ohm is built in.

    Frequency range:
    30 ... 80 MHz
