Antenna masts

I’ve got two types in my parts stash. Looks like most got the 60” telescoping mast. When did they use the solid mast?

Easy rhyme to remember;

The solid mast was new

For 1972

👍

Not sure where I got it, but I have a "4" piece telescoping antenna . . . it reaches the stratoshpere . . . ha ha ha, not sure what it would have come on, or even where I ended up picking it up . . . it is the screw in type, like the single mast . . .

Most of the telescoping ones have laying around have a longer threaded part on them. I’m finishing up a 70 Challenger and it will not accept the longer threads. It won’t screw down flush. I’m sure the base and antenna have been changed. I have several solid masts and they all have shorter threads. That is all that will fit this one.

How would a 70 PM43 have had a fixed mast antenna? .Car was bought new in 6-70 R11 radio.

Here are pics of the big long 4 piece antenna . . . 76" total length when extended !

Solid mast started before 72 are you 100% sure on this?
so all A Bodies before 72 are telescoping

Think that 69 or 70 started the single solid mast antenna . . .

I can beat the topic to death if you like? I'd have to find my file on it.........

Not 69 cars. Maybe it started sometime in 70 or 71 but not in 69.

Did fm cars get the same one as am radio.

I have 1970 AM, AM / FM & AM 8 track cars here. All telescopic.

Then, later on - the 1972 model year began..........

So can you give me a plausible reason for the above??

They can be swapped out in a few minutes if one was broken, stolen or damaged.

Check your owners manual, the part about adjusting the antenna. ;-)

From the 1970 FSM;

From a 1970 owners manual;

I have a 50,000 mile '69 RR with AM radio and telescoping one.

Mopar dealers sold an extra height, telescoping antenna, for areas with poor radio reception. For the post above that has the extra long piece, that is probably what it is. A little thicker as well
