13 cm

The 13-cm amateur band holds particular appeal for future amateur activities. Its proximity to the MDS band permits use of inexpensive 2-GHz downconverter receiving systems and 2.3 GHz transmitting gear in a very cost-effective manner.

A group of amateurs in a given area can actually become operational on 2.3-GHz for a lower expenditure than on almost any other amateur band. Direct communications on 2.3 GHz typically range from 20 to 60 miles, depending on terrain and the antenna systems employed. This spectrum is especially attractive for such wideband signals as multichannel fast-scan TV, multiplexed data links, computer interlinks, etc.

A number of 2-meter repeaters could also be linked via 2.3 GHz, and the line-of-sight propagation would permit ' peaceful coexistence of several of these services in any particular metropolitan area.
