I have followed the mfg instructions to the letter for almost 50 years as a
ham and 31 in broadcast tv and radio. Very few problems with solder or
crimp connectors. When I did have a problem, it was because I didn't follow
instructions. Directions for connectors are in the handbook. Fishing the
braid thru the holes is loony. Need heat? Use one of the mini-torches.
Use flux and a little vise.
It is vital that instructions be followed on heliax type cable. To the
letter.
