History

Presents guidance for engineers concerned with the design, specification, installation, operation and maintenance of radio systems. It is particularly directed towards systems working in the Very High Frequency (VHF) and Ultra High Frequency (UHF) bands but encompassing a measurement range between 9 kHz and 56 GHz in respect of compatibility where co-sited operation of many different users' equipment has become common. It does not specifically cover the detailed technology associated with microwave systems, operating at frequencies above 3 GHz.
