If you deal with antennas and RF cabling, you know how problematical these components can be at times. Lightning, wind and vibration, and ice and water can wreak havoc on antennas and separable interconnects. The sun's ultraviolet radiation can also prematurely age cable jacketing and dielectrics. The same is true for long-term temperature cycling. Then there's those pesky airborne pollutants, a factor especially troubling in urban installations.
Pollution can corrode connector backshells and even internal contact surfaces.
Perhaps its only limitation is the fact that the handheld is limited to characterizing antenna systems that operate at UHF between 806 MHz and 2.3 GHz. If your RF system operates below 806 MHz, this instrument isn't for you. Unlike many instruments these days, no PC is needed for operation. One feature that's quite appealing is the box's pop-up menus. They contain pre-stored information on over 70 coaxial cable types.
