It has a decal on it that says Shake Spear and they did make a 1600 model but I am not sure that 1600 refers to the length? Nor does it say 1600 on my antenna either. Just guessing. My friend bought it new and gave it to me when he moved away about 25 years ago. I have stored it since that time. Thanks for trying. Much appreciated.
If anyone else out here knows about Shake Spear big stick antennas please let me know.
