                         Tuning instructions and set up measurments below

If you check the swr and it needs  adjusting.

Start by loosening the set screw that holds the gamma match outer tube in shorting bar.

Move outer tube closer or farther away from the SO-239 connector until lowest swr is found.

If swr is still to high, loosen the set screw on shorting bar that holds it to the element.

Move the shorting bar closer or farther away from SO-239 connector until the lowest swr is

found. A combination of both will yeild a flat swr at the desired frequency.

Tighten set screws when done.

Measurments shown are a starting point only

  

* I get asked all the time which is better Square or Round.

  Testing shows no difference in performance
