Notes to Schedule 1
(a) dBW is the power level in dB relative to one Watt.
(b) Peak envelope power is the average power supplied to the antenna by a transmitter
during one radio frequency cycle at the crest of the modulation envelope taken under normal
operating conditions.
(c) Effective radiated power (e.r.p.) (in a given direction) is the product of the power supplied
to the antenna and its gain relative to a half-wave dipole in a given direction.
(d) ISM is an abbreviation for industrial, scientific and medical applications.
(e) In all frequency bands, high intensities of radio frequency radiation may be harmful and
safety precautions should be taken. Advice concerning safe levels of exposure to radio
frequency radiation is provided by the Health Protection Agency.
