In addition 20 channels in the 934 MHz band were also legalised, but equipment was considerably more expensive than the well established 27 MHz sets. At first the range was limited, but as antenna restrictions were lifted and better equipment started to appear, the number of UHF CB operators grew. In 1988, it was announced that the manufacture of 934 MHz equipment would be prohibited, though the use of existing equipment would remain legal. Its use largely confined to enthusiasts and amateur radio operators, the type approval specification for this band was finally withdrawn on 1 January 1999 and it is now illegal to use this equipment in the UK.
