Signal Staff Collapsible OSJ

The Signal Staff is a dual band 2 meter / 70 cm Open-Stub J-pole from S&K Antenna Systems!

This is a new antenna for us here at Signal Stuff made by S&K Antenna Systems who are friends of ours and have assisted in many aspects of Signal Stick manufacturing! We will have more information as we go, but to get them up and listed we’re working incrementally.

The base to this is designed to mount with a 1/4″-20 threaded screw such as is commonly used to mount cameras; this makes it easy to use a portable tripod or any other mount used for cameras. If you want to mount to an antenna mast please select “Add an angle bracket for mast-mount”

  • Dual band (2m / 70cm)
  • Strong, rigid construction
  • Easily fits in your go kit!
  • SO-239 connector
  • Lifetime warranty against factory defects; damage due to misuse or accidents are on you.

You can find assembly instructions here. Read below for more information!

The dual band Signal Staff might just be the best antenna for a portable go kit; though fully assembled this antenna is about 60 inches tall, it collapses to fit easily in a small bag with the longest piece only 11.5″ long! Pair with a simple foldable camera tripod and you have an antenna you can carry around with you wherever you want to go which can handle as much power as you want to push into it!
