Site Master is designed for field requirements. Its rugged construction sur-
vives rough field treatment. Battery power, light weight, small size, wide
temperature range, and simple user interface are exactly what field techni-
cians want today. Technicians can test antennas from ground level be-
cause Site Master’s distance-to-fault measurement compensates for cable
insertion loss. Furthermore, spectrum analysis, available in certain Site
Master models, allows technicians and field engineers to quickly identify
and solve common RF system problems, such as coverage, interference,
and other path related signal problems. Site Master offers a new and bet-
ter method to install and maintain transmission lines and antennas.
