“No Compromise Communications”

SGC — The SSB People

SGC develops, manufactures, and sells high performance single
sideband (SSB) communications equipment. Since 1971, the compa­ny has sold to the marine, military, aviation, and industrial markets
world wide. Over these years, SGC has earned an outstanding reputa­tion for product reliability and for service after sale.

The company keeps pace with equipment options, engineering
developments, and design requirements. Its products are the most
competitive in the entire long distance communication market. SGC
equipment is presently being used by the United Nations for
inter-communications in developing countries throughout the world.
Many competitive racing vessels, as well as fishing boats, tugs, and
commercial craft are equipped with SGC equipment. In fact, an SGC
radiotelephone provided the only communications available on a past
Polar expedition by the National Geographic Society.
