1. Start with VSWR and DTF if needed to check transmission
2. PIM test the cable with the antenna connected, 2x40W
3. If PIM fails, use DTP to locate hot spots Establish location of the antenna by connecting a PIM Standard after the cable You can then see if PIM is caused by external sources
4. Remember to tap (dynamic) test all Hot Spots as well as the Lightning Protector, Current Injector (Bias Tee), Connectors and ground at attachment points
5. Correct any PIM Hot Spots
6. If nearby objects (rusty objects near antenna) are causing PIM failure, report these to the antenna owner for resolution
