Surplus antenna factory parts. YOU GET FIVE 5 for the price. This unique spring was used for making portable radio antennas like walkie-talkie, for VHF and CB 27MHz band (requires the other coil at another list for 27MHz) This is US made stainless steel. It is 6 inches long, and 5/16" diameter (exactly 0.306"). It has 16 turns per inch. The wire is .034" and a coil ID of aprox 0.235".
I have the brass end-fittings for this on a separate listing. NOT included, see it in a picture. No returns, closeout, there are hundreds of them.
