Ultra High Frequency (UHF) Band The UHF band goes from 300 MHz to 2450 MHz, although TACSAT manpack UHF radios do not utilize frequencies above 512 MHz. The wavelengths associated with 300 to 512 MHz range from one meter to 0.58 meters (58 centimeters). The very small antennas required for these wavelengths make them ideal for use on high-speed aircraft. Frequency Allocations Within the HF

The range of frequencies of RF signals is called the radio spectrum. It starts at 20 kHz and continues through several hundred GHz, a thousand million times higher in frequency! Signals below 20 kHz are audio frequency or AF signals. For convenience, the radio spectrum of Figure 2-20 is divided into ranges of frequencies that have similar characteristics as shown in Table 2-3. Frequencies
