Gain difference between mounting the HexTenna 15 feet vs 6 feet.
Spoiler alert: Moving the HexTenna from the 5 1/2 foot HD Tripod to a 15-foot mast increases your signal by half (1/2) an S-Unit.

Boom Doubler Option
Our boom doubler, which will be released later during this Summer of 2024, increases the length of the boom to 96 inches/2.46m. This is done by adding a supporting boom, which is called a ‘joiner’ under two 48 inch booms. Once the two booms are mounted on the joiner with included hardware, then a mast clamp is then affixed at the center of the joiner. This mast clamp will then affix to any standard 1.25 inch mast.
