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.

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;
