I was installing my Blau Frankie and went to insert my antenna plug - and the plug pulled off the shielded cable. It looks like there is a hair sized wire coming from the inside of the plastic tube surrounded by the braided shielding. Is that correct? That small wire should be soldered into the male end of the plug and the outside "leaves" of the plug should be soldered to the braided shielding, correct? How do you get to that piece of hair sized wire inside the tube? Thanks for your help.
