Plastic washer on cb connector? Why?

[Delivers1234]

I made a hole in my dish (old direct dish tv) to add a CB antanne but the hole I made was too big and now the antenna wobbles. The plastic washer has a smaller ridge to it.

Do I need it? Anyway around it? Anyone know the exact size to drill?

yes you need it,, and the size varys with manufacturer,,,,, even if put on an old dish antenna,,, i would think the ground side of antenna would not be right and the swr would be way off ,, possibly causeing damge to your radio,,,,,

Yes, you need the washer, it keeps the center conductor from shorting to ground. If you drill the hole too large, you have to start over. Measure the small size of the insulator washer and select your drill diameter accordingly.

Measure twice, cut (or drill) once. If you do it wrong, you have to start over.
