Hi Terry, 


I've had the same problem with some PCB mount F connectors. 


eBay has multiple sources for soldering lug you need, 
this is the least expensive of them

I am having trouble constructing the YCCC feedline chokes as 
described in their manual. In particular, I cannot seem to solder the 
RG-179 to the PCB mount F-connector, even after studying the 
photos in the manual. I had no problems soldering the BNC PCB 
connector in the FA-VA5 antenna analyzer kit with the same 
soldering equipment. The RG-179 and F-connector are in the 
commercial kits I purchased. The shield keeps pulling away from the 
connector after the solder cools. 

Does anyone know where to obtain the soldering lugs that fit under 
the nuts on chassis connectors? When I look for 3/8 inch lugs I 
keep finding lugs to hold 3/8 inch diameter power cables!
