When you operate as HP station with one or more amplifiers and receivers, thinking about how to protect your receiver against overdriving is must.

Aleš, S59MA developed great, low cost and very effective limiter for use on HF band with vy small losses. We built 5 pcs., specially for use in this contest. The measurements showed losses from 0.5 dB to 0.37 dB (160m to 6m).

If you would like to have such limiter too, you can buy it here. It’s professional made, measured and ready for use.

Aleš, many thanks for your contribution for our contest event.
