Crimp Connectors – Setup from DavisRF

Order arrived (I installed the dies for the picture)

When I pulled the LMR-400 for my Island QTH’s ZeroFive Flagpole vertical antenna, Tom K0TTC brought over his DX Engineering crimp connector setup to put the ends on (UHF connectors).

I rather admired his setup, and when I was ordering cables from DavisRF asked them about crimp connectors, and they said that I could add the tools and connectors to my cable order, no problem.

The crimp dies come separate and are easy to install. I could have bought just the dies, as I have standard sized crimp tools in each QTH’s PowerPole install tool kit, but I elected to get the whole tool to avoid the likelihood of ending up losing something later.

Bought 24 each of N-connector male and UHF-connector male crimp assemblies.

When I have done these in the past, and when K0TTC and I installed my last run, the center pins were also soldered.

Technically the industry makes a distinction between Crimp, Clamp and Solder styles of amateur radio connectors, with Crimp further dividing into soldered-center-pin and crimped-center-pin versions.

“Clamp” refers to a connector which utilizes a threaded sleeve to secure the connector to the cable. The center pin is soldered. “Crimp” refers to a connector for which the body (shell) is crimped onto the cable (with a crimp tool), making shield contact, and the center pin can be either soldered (preferably) or crimped. “Solder” refers to a solder on design, requiring soldering of both the center pin and the body to the cable shield braid.

So again I am doing Crimped soldered-center-pin.

Nothing against DX Engineering, as the DavisRF setup and supplies was about 2/3rd the spend, though I don’t get the swish DX Engineering branding going with pro-level commercial grade kit and supplies.
