Specification: Expanded length: 5.6m/18.4ft Number of sections: 14 sections Weight: 285 g/0.6 lbs Folded length: 50 cm/19.7 inches (including nuts) Connection nut: M10 (external thread) First part diameter: 16mm/0.6" Distal diameter: 3.6mm/0.1in Material: 201 reinforced stainless steel Special Process: The 10 bottom sections all use secondary reinforcements to change the stress points and make them stronger and tighter. Of course, it takes a little more effort to fold and extend than an ordinary telescopic antenna. Therefore, upright shaking can be reduced and automatic retraction can be avoided, thus extending its lifting span. When extending, it is recommended to pull out section by section from the top, and when retracting, it is recommended to retract section by section from the bottom. Package Included: 1/2 x telescopic antenna
