UHF and VHF (that is, Ultra High Frequency and Very High Frequency) are the 3GHz-300MHz range and the 300MHz-30MHz range, respectively.
That translates to a 10cm-1m wavelength for UHF and 1m-10m for VHF. Minimal effective antenna size for a basic wire antenna is 1/4 the wavelength, so you end up with big antennas for low frequency / large wavelength.

- derstander 4y agoNote that different organizations use the same terms for slightly different bands. In the IEEE nomenclature for radar, UHF is 300MHz to 1GHz. 3GHz is solidly within S-Band. And L-Band is in between them.
