If you elect to use an antenna tuner, it is extremely important that you understand exactly how to use tuners and what they can and cannot do. A few watts of RF can easily become lost in an incorrectly adjusted antenna matching device. I cannot overemphasize the priority of a clean, efficient connection of the amplifier output to a resonant antenna.
