Crimped Connectors

[scannermanfremontoh]

I am looking to buy coax cable from a company. They offer 100 foot of LMR400 cable with the PL259 and BNC connectors crimped on. I would prefer soldered, but the company said that "professionally crimped" connectors is ok.

Are they correct or with crimped cause a problem with reception?

thanks in advance for any help.

Having crimped connectors professionally I would still solder the center pin of a PL-259, impossible with the BNC since soldering is internal. No biggie, that connector will be indoors where moisture ingress and corrosion won't be a problem. In any case tightly wrapping the outdoor connection COMPLETELY with electrical tape will take care of weather related problems.

The ones I have used,I have always soldered the center pin to the conductor(RG-58 ,that is)

If you know what you are doing, then crimped connections provide for a much more consistent quality connection than do soldered connectors. The trick is having the proper equipment and know-how. Many connectors are also a mix of crimp and solder. Many times the ferrule is crimped, and then the center pin is soldered on.

Personally, I have a whole world of connectors available to me, but I use crimp 99% of the time. The only time I use solder is when the connector comes in a clamp/solder only like Heliax connectors.

As far as your 100' LMR-400 jumper, does it have a UHF on one end and BNC on the other or what? I'd like to give you a quote on the exact jumper you need. For example, I sell a 100' LMR-400 w/ UHF male (PL259) on both ends for $88.50. The connectors are RF Industries silver/Teflon. I can do any custom length you need, not just 50 or 100 foot. Many others on here have my custom jumpers and can attest to their craftsmanship.

Thanks,
Jeff

Yes, crimping if done properly can be very reliable...the military uses it. Back when wire-wrap was still being used, I read that a good WW joint could outlast a solder joint by 2:1 (40 years v. 20 years).

Go to the Times Microwave site and check out their videos on installing crimp connectors on their cable. If they're not as good or better than soldering, I'll eat my hat. :lol:

I would prefer 85 foot cable with one male BNC on one end and a PL259 on the other end. Please give me a quote and tell me how to order the cable.

Thank you.

Thanks for all the replies. I feel much better about buying crimped on connectors on cables now. Crimped actually sounds like it is better than solder, if done correctly. Thanks again.

I really don't have any problems using crimped BNC's indoors, but as a general rule, all outdoor BNC's that I use are soldered and completely weatherproofed.

That's because a good WW is gas-tight - most crimps aren't. Apples and oranges.

It's the corrosion due to oxygen or water (actually water + oxygen) that causes most electrical joint problems.
