4.9 Defining Frequency Bands
Where test procedures or figures differ according to the frequency band of
the radio, the frequency band is given in brackets. The frequency band may
be referred to as either ‘VHF’ (very high frequency) or ‘UHF’ (ultra-high
frequency) or identified by the frequency sub-band, such as ‘B1’ or ‘H7’.
For example:
In some cases, differences in performance over the frequency band mean
that the K5 frequency band may be further divided, into “700MHz” and
“800MHz”.
The frequency bands for TM8100/TM8200 radios are listed in Table 4.10 .
The relevant frequencies for the different bands are listed in this table.
RF output power: > 60W ( VHF ), > 52W ( UHF )
current: < 15A ( VHF ), < 12A ( UHF )
