HYS TC-300 CB Band HF AMP for CB Band Handheld Radio Transceiver

  • The most effective working frequency is 10Meter to 15Meter, lower fever and lower VSWR.
  • About the working general output for AM & FM mode is around 100W and the most effective output is around 200 W with input 5 W and around 200-250 when the input is 10W..
  • The frequency of the connecting antenna is very significant. It is also should be connect with the amplifier corresponding frequency. If it is lower or higher than the required, it will not work and even will not only burn out the amplifier but also will damage the radio..
  • If you want to reach the PE MAX output, please check that the input should exactly 10W or 5W, the DC Power should actually be over 14V and 18A and also other conditions should be perfecT. Different mode have the different input requirement..
  • However, we do not suggest to work the PE Max for a long time,it will decrease the amp' life time and also if the antenna can not endure the output watt, which will damage the amp, thank you very much!.
