Product code:IS440

Single isolator for the low VHF band with a harmonic filter and a reverse load built in. Supplied pre-tuned, so send us the operating frequency with the order.

  • isolation 18 dB
  • insertion loss 0.9 dB
  • harmonic attenuation 80 dB
  • 50 W, built-in load
  • BNC-female connectors

The isolator sits between transmitter and antenna and passes power one way only, so a neighbouring transmitter cannot reach the output stage and create intermodulation on channels that are in use.

The reverse load is inside the housing, so no external dummy load is needed. If the antenna is damaged or disconnected, it absorbs the reflected power instead of the transmitter output stage — 30 W for two minutes with no extra cooling, and continuously when the isolator is mounted on an MP007 plate, inside a BS2000 cabinet, or otherwise given a thermal path to a heat sink.

This is the low band version, covering 68 to 88 MHz. Unlike the VHF and UHF isolators it is tuned to a bandwidth of 3 to 4 % rather than the whole band, so it is set to your frequency before it ships. Send the frequency with the order.

For the bands above, see the VHF 136-174 MHz and UHF 400-470 MHz versions, which need no tuning. Contact sales for special solutions.
