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
Radio antenna question / telescopic what year

@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.

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.

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
