I have looked at both ends of this issue ( pun is always intended ! ) I will be taking the advise of several hams concerning the use of crimp on pl 259 connectors .  My question is this ...  I just purchased a crimp on tool made by RF and lots of lmr 400 .  when I look to buy the pl 259s do I stay with my usual Amphnenol  or do I need to look for crimp on pl 259 s ?  can anyone recommend top shelf connectors for crimping use ?  thank you   John kb2huk

John, I went to crimp connectors about a year ago.  You best source is
RF Connections (http://www.therfc.com/uhf.htm).  Our amateur radio
club bought in bulk (RG-8X & RG-8 connectors) at a substancial savings.

According to an 'old, bold' comm tech, most of the contracts he worked
on required crimp connectors.  He discovered they typically swept up to
2GHz.  Crimp connectors also have better grip on the cable and don't twist.

You would also do well to follow installation with heat-shrink tubing on
the connector.

If you use the correct Amphenol connectors (the Pacific rim junk isn't up to snuff), and the right crimp tool (about $100 plus dies), they are as good as any solder on. Probably better, as most folks don't know how to solder the standard ones correctly.

My biggest complaint, however, is the size of the barrel. It's shorter length makes R&R more difficult.

Although I like a good soldered connection, the use of "foamed" dielectrics and aluminum conductors in some of the newer coax cables practically require a crimped connector.  And a good crimped connection is better than a poor soldered one!
You can't go wrong with Amphenol.

Just to be completely clear about this, you CANNOT use solder-type connectors and crimp them on.  You must get connectors that are specifically made for crimping.  Perhaps I have misunderstood, but based on the quote above, it seems to me that that is what you were really asking.

I have also had great results using crinp-on connectors from www.therfc.com.  I use the High Sierra $50 crimping tool, which works great.  To strip the coax, I use the DXE coax strippers - however I have to trim the center conductor of the stripped cable down in length as the DXE strippers are designed for solder-on connectors.
