Band IV / V UHF 470-862MHz UK TV Broadcasting. SDTV, DBV, HDTV PAL UK AM vision carrier lower sideband vestigial FM sound and 25kHz guard band
L UHF 1-2 GHz Many MOD frequencies exist in this band. ALL transmissions are banned at 1.4 GHz 1.8 GHz is DECT Other uses in radioastronomy; SETI is at 1.420
S UHF / SHF 2-4 GHz 3G mobiles, air telemetry, some MOD frequencies C Band satelite 3.7 to 4.2 GHz
C SHF 4-8 GHz Satellite TV in Asia C Band is impervious to rain fade but suffers from ground interference
Ku SHF 12-18GHz European Satellite High Level MOD The topmost band you are likely to come across.

Frequencies and Wavelengths

VLF ~ 15 kHz 30 kHZ 20,000 m 10,000 m Long
LF 30 kHz 300 kHz 10,000 m 1,000 m Long

SHF 3 GHz 30 GHz 0.1 mm 0.0001 mm Microwave
EHF 30 GHz 300 GHz 0.0001 mm 0.00001 mm Microwave

For VLF the min of approximately 15 kHz is given as radio waves do not propogate much under this. C is given as 300,000,000 m/s but more accurately could be given as 299,792,458 m/s.
Wavelength l = speed of light C divided by frequency f :

l = C / f

In the United Kingdom analogue frequencies are given a channel number more usually than a frequency. If you need the frequency, it's given by the equation:

fvis= 8n + 303.25

Where fvis is the frequency of the visual carrier and n is the channel number. Then you take off the 0.25

For digital the equation is:

fmux= 8n + 306

where fmux is the centre frequency of the multiplex band you're trying to get.
