Hi Win
Without actually looking up the model/manufacturer I'd say it is an
antenna meant for circular polarised satellite work. The switching
system probably changes LHCP RHCP but may also have a planar (V or H) mode.
Now doing a websearch;
KLM Antennas - Closed factory - Out of Business the last day of Oct.
1999 - See M2 inc have KLM spares
This may be it;

I have a freind, a new ham, that was given a 2 meter vetically and
horixontally polorized antenna from an estate. The antenna is marked
KLM C-3. It had two 300 ohm driven elements. It also has a switching
circuit that apparently attaches to the feed points.
Can anyone that is familure with this antenna give me information on
how to use this circuit to feed tha antenna.
