Anritsu Site Master S331D 25 MHz – 4 GHz Cable & Antenna Analyzer

Anritsu Site Master S331D 25 MHz – 4 GHz Cable & Antenna Analyzer


Wireless market competition requires operators to reduce per site maintenance expense. Anritsu Site Master’s Frequency Domain Reflectometry (FDR) techniques break away from the traditional fix-after-failure maintenance process by finding small, hard to identify problems before major failures occur.

Sixty to eighty percent of a typical cell site’s problems are caused by problematic cables, connectors and antennas. When cables or antennas are contaminated with moisture, damaged, or mispositioned during storms, Anritsu Site Master S331D 25 MHz – 4 GHz Cable & Antenna Analyzer identifies the problem quickly. Antenna degradation reduces the cell coverage pattern and can cause dropped calls. Site Master can pinpoint the antenna problem from ground level in a few seconds making climbing the antenna tower unnecessary.

A poorly installed weather seal will corrode connectors and, if undetected, will eventually damage an expensive coaxial cable. Anritsu Site Master S331D 25 MHz – 4 GHz Cable & Antenna Analyzer has the sensitivity to identify the connector problem before the cable is damaged. Distance-To-Fault provides the clearest indication of troubled areas.
