This booster CB for 26-27Mhz schema, using power IRF transistor, for lower cost your experiment. and
more easy to adjust RF power. in this schematic, i am using IRF 540N , it can be made power output about
50 until 60 Watt For normaly DC consumtion 12,5 - 13,8 volt. for bias G (Gate) for this IRF transistor, i am using 1,5 until 2,2 Volt for safety the IRF transistor. please make sure the G (Gate) bias voltage (Set to 1,2 Volt) before your conect IRF 540N On the PCB. For C (Condensator) Couple on Input and Output , you may using Trimer capasitor or Fixed capasitor. for best quality power output and impendance, i recommended using Trimer Capasitor for easy adjusting Zi and Zo until best power and good impendance
(50 Ohm).

Ok Everyone, that's all I can tell about my homebrew CB HF Booster, and please rest you modify it yourself to be better. thanks and happy homebrew experiment.... 73's....
