Cable Termination: PL-259 onto LMR-400 Coax
I have a radio. I have antennas. The next issue is to connect them up to each other.I purchased some Times Microwave LMR-400 from AES up in Euclid. Over lunch I became the proud owner of 75 feet of the stuff.The issue is that to save money I got the cable unterminated. Yes, I'm a cheapskate. I got the cable and five Amphenol PL-259 connectors. I only really need two of them, but I planned ahead. I planned ahead to screw up!It turns out that it's not hard at all! :-DSo here's the steps:
- Strip 3/4" down to the center conductor.
- Remove 5/16" of the outer insulator.
- I found it easy to make a slice around the cable, then slice it open and peel it off.
- Slicing and pulling just seemed hard and led to fraying the shield
- Tin the shield and center with a bit of solder
- Make sure you put the outer part on!
- Screw on the inner part onto the cable
- Solder the four holes to the shield
- Solder the inner connector to the center pin
- Screw the outer part over the inter part
If you skip step 4, you won't be able to actually connect things up![smugmug url="http://photos.vec.com/hack/feed.mg?Type=gallery&Data=15787394_dExiM&format=rss200" imagecount="100" start="1" num="100" thumbsize="Th" link="lightbox" captions="false" sort="true" window="true" smugmug="true" size="L"]Excuse the shredded-looking outer insulation... with the short cable I didn't have enough to hold onto. It didn't look like that before.
