You can purchase the Xiegu XPA125B and it works well with the G106, but I doubt that you will want to spend 5 times the cost of your G106 for the amp!? ?A good quality amp costs money unfortunately.? There are some kit amps in the $250-300 range but I have no experience with them.? ?I have a Xiegu XPA125B but I got it to go with my G90.??

p.s.? Remember that not only is the XPA125B an amplifier, it also has a built in automatic wide band? antenna tuner.??
