MaxOptimizer allows you to choose between a balanced 10 -11 meter antenna that will perform well in both bands or optimize the antenna for the 11 meter band.
To Optimize for 11 meter performance assemble the antenna with the 12” optimizer section installed between the mid and top section as a 4 piece antenna.
For balanced 10-11 meter performance leave out the 12” optimizer section and assemble as 3 piece antenna.
