Radio antenna question / telescopic what year

[davek]

Was the telescopic antenna an option? What year did it come out? Want to replace mine on the 70 charger. My 70 Bee is not telescopic, My 69 charger that I owned was not either. Thanks

@Richard Cranium did 68 have telescopic antenna?

As far as I know, all 68-70 B-bodies all had telescoping antennas.

71 down telescoping, 72 up solid mast.

Before Bob chimes in

And then there's the matter of aerial antenna length...

31" is approx the length of a quarter wave length at 90MHz which is about the center of the FM broadcast band. So the antenna is sized for FM reception. Ideally, you either use the full wave length, which would be impractical for a car at 124". From there, it has to be split in half and then halved again for a quarter wave.

@davek do you have an AM radio or an AM/FM radio?


The '70 Mopars had a telescoping mast to accommodate the various frequency ranges of AM stations. On the side of the radio there is an antenna tuning screw to further fine tune a specific station. The mast when fully collapsed is about 31" which is proper for FM stations if the vehicle had an AM/FM radio. Improvements in solid state radio receivers led to the adoption of fixed antenna masts about 1971.

Wayne I have the AM radio but I know a guy that has the Holy Grail AM/FM radio.

That reminds me @davek ...my '70 Charger does not have the telescoping aerial antenna.

Both my '64 and '66 have telescoping antennas.

Have your metal guy weld-up the hole for the antenna.

I will suffer with my AM radio. Dont think they make a deeate plate for that

 

[davek]

You better call your legislators, they’re trying to do away with the A/M
Radio’s.

My 68 GTX has an AM radio and a solid antenna.

I have an audiovox FM converter for sale Dave.

These 68-70 antenna masts are a screw in part. So if they break is is a two minute task to install the incorrect but common solid antenna mast. These cars are now 5 decades old so things happen.

My antenna is a screw-in solid part

My '70 was 15 years old when I bought it, but lots of things can happen for sure.
