A review on operational distance enhancement of the ultra high frequency (UHF) in military radio

Ultra High Frequency (UHF) remains the most used frequency band for two-way radio communication in military telecommunications. The output power on the military radio which measured in Watts will determine the effective range of the UHF signal. The transmission and reception of the UHF signals could also be easily degraded by many variables such as atmospheric moisture, solar wind, physical obstructions such as mountains and buildings. All the obstructions cause the signal degradation which will limit the operational distance of the UHF signals. The main objective of this study is to eliminate the signal degradation solely by using an amplifier circuit that will act as a device to increase the power of the signal. The purpose of designing circuits in this study is to increase the output power of a transmitter which later on can replace unnecessary antenna.
