Re: No ground plane antenna needed for fiberglass
“Sherman set the way-back machine for 1975.”

“To see C W McCall and hear him sing Convoy, fer sure, fer sure.”

Yep, about the time all this was goin’ on, they made no ground plane antennas for boats and such. Maybe you need one and maybe you don’t. Some people had good luck without them on ‘glass bodied cars, some could only talk if you were in front of him.
At the end of ’76, I think it was, maybe a year or two either way, 25 channels sets became obsolete and everybody and his brother got one of the marked down 25-channel sets for Christmas. There were experts all over the place and they all learned how to “pin your coax”.
You was doin’ pretty good there Dawg, even had the “V” in front of “SWR”. But;

And contrary to popular mis-belief, the coax length is not an issue....I've heard some people say that you can't shorten the coax because that will upset the VSWR.....WRONG. The coax has a fixed impeadance....regardless of the length...which is differnt from signal loss.

Sorry, it’s true. You either tune the antenna to the coax length or trim the coax to tune to the antenna. Fixed impedance of the coax isn’t the problem.
I also would not drill a hole in the role cage. If it were square tube, channel or “I” it would be ok but with round it will weaken the tube.
