If you need to adjust the gamma match for a lower SWR,
Loosen both set screws on the gamma match shorting bar. Move it to where the swr is the lowest. Retighten
set screws when done. It should be some where around 2-1/4 to 2-3/4" Start at 2-1/2"
The frequency is set on this loop through element length and gap at element ends.
The element length is already set.
You can change the distance between the element ends by spreading them apart or pushing them closer together.
The frequency center will be where you have the lowest swr.
Check to see at what frequency you have the lowest swr.
If it is not where you want it , to change it, first measure the distance between element ends to give you a starting
point. Then proceed with spreading apart or reducing the distance.
The greater the distance between element ends, raises the frequency.
Reducing the distance will lower the frequency.
Measure the distance each time and recheck the frequency to see where you now have the lowest swr.
Once you get it where you want it, Write down on a sheet of paper what the measurements are. This will make it
easy to readjust it at a later date if needed.
Measurments shown below are only a starting point.
Always mount loop with gamma match and mast clamp on bottom side of loop.
