Ronin: thanks for the reply. I don't think you are relating to a newer version of the same antenna (RS 20-161). When fully extended =40". When fully collapsed antenna is 15-3/4" from base to top of center coil. The first section is fixed,(non-adjustable). the other 5 sections are telescoping @ 5" per section.
