Topband: PL259 type connectors for RG11

[Rick Kunath]

DX Engineering has some that would work I think. It's a crimp on the 
shield and a soldered center pin.

Not sure if that would work for your application? I suspect that the 
larger sized center pin needed for 50 ohms would make a crimp to the 
center pin problematic on 75 ohm cable in a 50- ohm connector.

I've never used these connectors before but I might now that I see them.

Any cables I make up with PL-259 connectors i have been soldering both 
the shield and the center pin.  On the shield end I strip the jacket and 
flux and tin the braid. Then I measure for center pin length, and use a 
tubing cutter to cut the tinned shield to the right dimension, clean the 
cut edge to remove any bits of metal and screw on the PL-259. After that 
I remove the tip of a Weller 125 watt soldering gun and after fluxing 
the 4 solder holes in the PL-259 I bridge the connector across the 
soldering gun ends where the tip usually goes. The connector becomes the 
tip, heats up quickly and a quick application of solder and its soldered 
all around. I let it cool before moving it and then quickly solder the 
center pin and trim it.

I've had good luck doing that over the years (so far).

For N connectors it's always a shield crimp but I solder the center pin on.
