License Free Ultra High Frequency (UHF) Radio Communication PDF Print E-mail

A restricted number of Licence Free UHF Radio Frequencies were authorized in South Africa for specific UHF short distance applications.

The power output of the Radio equipment that qualifies in the licence free applications is restricted to 500Mw and can be used indoors over distances of a few hundred metres to outdoor applications of typical less than 2 km in ideal conditions.

This is a Low Cost solution and typical applications are:

  • Outdoor – hiking, safari, hunting, rafting, e.t.c.
  • Sport activity.
  • Entertainment.
  • Farming.
  • Neighbourhood watch.
  • On-site Security.
  • Schools.
  • Warehouses.
  • Wholesale and Retail environment.
  • Factories.
  • Building and Construction Sites.
  • E.T.C.

Technology to extend the range of this low power UHF capability is now also available by the application of:

  • Mobile Magnetic antennas for vehicles in convoy.
  • In the Static environment:
    • Parrot repeater – simplex recording and retransmitting of the message by means of a parrot repeater system and effectively doubles the distance.
    • Software repeater – combination of a standard radio linked to a Computer that receives the message, records it on software and retransmits it via the same radio at the Computer.  In essence also a parrot repeater.
