Antenna extra wire

Post by Solo So Long »



I'm no stranger to wiring. I'm no stranger to antenna cables. But this one has me stumped!

The broadcast band (AM/FM) antenna has the normal coax cable, terminated in a Motorola plug.

However, there is a second wire coming out of the mount, that terminates in a male bullet connector. This is the one that I don't know why is there.

Anyone know about this?

If it looks like this, that is the AM coax to plug into the AM receiver input jack.
If that cable is not plugged in, you won't have any AM Radio reception.

Head scratcher. Just a normal braided wire with a connector? Just be guessing without taking the antenna mount off. Could be an attempt to improve the ground but could also be power to the flux capacitor (or from the flux capacitor I suppose). Best to tape it off and leave it unless something isn't working.

If I'm hearing you correctly, it's the ground wire. Needed to create a ground plane as the bags are plastic and not too good a ground which is needed for proper reception.

Receive only antenna and the sheath of the COAX should provide an adequate ground. The extra wire has been added by parties unknown and could cause problems if connected to power or ground without knowing where the other end goes.

Is the wire color coded green with black tracer or dark green? If that's the wire color code then it's a ground wire for the antenna.

That's a standard Motorola plug.

I'm asking about a SECOND wire that comes out of the antenna mount, that has a bullet plug on it (as if carrying DC).

A ground wire? Maybe, but the Motorola plug grounds the coax sheath, and the CB antenna doesn't have this extra wire.

I would vote for it being a ground wire and this is why, if it were anything else there would be a different or dedicated plug not a standard bullet plug. Engineers have a thing for specialized plugs not only to make it easier to see what mates with what but "just because". The only exception is something very basic and standard like a ground and even then they may make it a more "proper" connector. Back in the day bullet connectors were common but not so much now.

You might try to prove that it's a ground with an ohm meter, see if it has 0 ohms to the base of the antenna.
