With vast experience conducting external PIM hunts in the field, ConcealFab has identified the most common sources of external PIM found in the high-risk PIM zone near antennas at cell sites. The PIM Hygiene application note identifies the most common PIM sources encountered and provides solutions for mitigation. In addition to the obvious problems, such as metal snap-in cable hangers and stainless-steel hose clamps, a wide variety of not-so-obvious sources and solutions are identified.
Performing PIM Hygiene should be the first step in mitigating external PIM at a cell site. Before sending highly trained Test & Measurement (T&M) crews to the site with expensive gear to hunt for PIM, have construction crews eliminate all the obvious problems first. This will save time and money in the long run by allowing the T&M crews to focus on the more difficult challenges.
