I can find crimp crimp but I want crimp solder (center)....  It seems tough to find any at a decent price (HRO is outrageous in pice compared to the manufacturer price).

What brand do you use and where do you buy them?

Thanks

I get mine from RF Industries. I use the RFU-507-S. Here's the link:

I buy my crimp coaxial connectors from RF Industries OR RF Parts (just down the road).
Retail prices are often close.  Watch for specials OR order in quantity of 10.

RF Industries - Specials

RF Industries - Excess Inventory

It is easy to add some RFI connectors to an RF Parts order, to meet minimum orders!

What's the difference between s, si, st, and stf?  I don't way to get the wrong plug.  I am using the ex engineering lm400 cable.

Thanks

It's somewhat confusing. This link is a good reference for the UHF male crimp connectors.

I believe you want the RFU-507-SI for LMR-400 type coax.

RF Industries sells three major connector types:
CRIMP, CLAMP, SOLDER

RFI Connectors are numbered and categorized by:

Type Connector (UHF, N, mini-UHF, BNC, SMA, etc.)
Male or Female
Install type (Crimp, Clamp, Solder)
Outside diameter of coaxial cable (0.405", etc.)
Cable Group (letter), for the coaxial cables the connector is designed for.
Connection dielectric: DAP (phenolic), PTFE (Teflon), Delrin, etc.
Finish of connector body and contact: Nickel plate, Silver plate

RFU-507-SI
http://rfsearch.rfindustries.com/ShowProduct.asp?classID=20&productID=5810

UHF (PL-259, Male) for 0.405" cables, CRIMP : RFU-507
Silver plate and PTFE dielectric : S
LMR-400 coaxial cable, Cable Group : I

DRY FIT, BEFORE crimping.  I have found some minor errors in dimensions (typos) and
sent corrections to RFI - so always check work for first-time crimp.

YES, mistakes are easy to make -- IF you don't pay attention to characteristics.

In order for crimping to work properly, you need a close fit between the sleeve being crimped and the metal underneath.  LMR-400 has a lower loss than RG-213 because it has a fatter center conductor--you won't be able to fit a crimp RG-213 center pin onto LMR-400.

RG-214 features two outer braids--you won't be able to get the RG-213 crimp sleeve to fit.

S is for silver and T is for Teflon.
