If you’re anything like me, I’m certain you can recall your mom’s ear-splittingly shriek at one point or another … “this is why we can’t have nice things…you need to be more careful”.
The simple fact is…it’s the truth… things do last longer when we take care of them. Today, we may no longer leave our new bikes out in the rain, but what about how we treat the RF/Microwave Components we use everyday on the job!
Below are some helpful hints to treat your Connectors well so they’ll have a long, productive and reliable life.
1. Don’t use pliers on a “stuck” connector for any reason. There are wrenches for every size adapter, even SMAs bullets. If you can’t fit a wrench to the stuck connector, see below.
2. Learn how to clean connectors with alcohol and cotton swabs. Cleaning the threads is good practice, but stay away from cleaning the center conductor of an air dielectric connectors such as 3.5mm, 2.9mm and 2.4mm.
3. Learn how to gage connectors to determine if they are out of spec. One bad connector can damage many.
4. Don’t use higher frequency connector than you need. Save the 2.9mm and 2.4mm parts for millimeter-wave measurements.
5. Never use any part of a calibration kit as an adapter. Ever. If you need a special adapter, buy it!
6. Use a torque wrench. For most connectors with 5/16 inch hex nuts, use 6-8 inch-pounds. It’s OK to use less torque, but not more.
7. Don’t forget, righty-tighty, lefty-losey! The total damage done by people turning stuff in the wrong direction is second only to damage caused by klutzes who “thumb” hybrids.
8. Remember, you are not tightening lug nuts. The hardware you hold in your hands could very well be worth more than your automobile. So be gentle with it.
9. When you are tightening or loosening a connector, try not to spin the mating surfaces against each other. You should only be turning the threaded sleeve. Turning the mating surfaces means you are wearing out the connector for no reason!
