Telamon,

From the description it appears to be simply 24 Feet
of a Single (1) Wire {Heavy Gauge} Speaker Wire
connected to an "F" Connector as the FLEX-TENNA

I think that one of those Roll-Up {Reel} Portable
Shortwave Antenna's would do about the same
as the Grove Flex-Tenna for Shortwave Listening.
