Abstract : The report describes the development of a crossed log-periodic dipole antenna system for the UHF frequencies of 225 MHz to 400 MHz. The antenna system is manpackable due to its low weight and volume. The system consists of an antenna, mast, and pack. The crossed log-periodic dipole antenna has folding elements to permit storage within a circular mast section. The multisection mast is made of individual telescoping units which are identical. The telescoping units are fiberglass to permit rough handling in the field without permanent damage. The antenna can receive or transmit both polarizations simultaneously. The nominal impedance is 50 ohms unbalanced with a VSWR of 2:1 over the frequency range. A minimum gain of 2.69 db above isotropic when measured at the base of the antenna mast was obtained. (Author)
