Re: Glass body and antennas

The antenna is grounded through the cable you plug into the radio, there should be no need for a separate ground wire.

Actually it works both ways, if the antennae is grounded to the vehicle, the radio will work w/o a ground wire, some manufactures rely on the antenna ground for the radios ground. Either way, the antennae should have a ground to the chassis. I did install work for 10+ yrs. and we used to have people come in all the time with poor reception on the radio, we pull the antennae, run some sandpaper around under the fender, re-install the antennae and reception was again good. We also had mysterious noise problems that happened, again pull the antennae, clean the ground, reinstall and the noise went away. On boats you can run them ungrounded, and have reception, ground it and it works better, but these are just my experiences, it's pretty easy to run a jumper to test wether it's worth your trouble.
