World Class Output

Intelligent AGC/ALC

Every process is automatic. Because we have smart AGC and ALC built in each amplifier. No re-tuning or re-adjusting, AGC/ALC take care of everything.

AGC allows for auto-adjusting based on the input signal strength and then provide the necessary level of output signal, so as to avoid interference, get steady maximum reception, and keep the amplifier a longer service life. While ALC allows for auto-control of the maximum permitted power to get the best working performance according to the actual network traffic.

ATNJ promises you brand-new and high-quality AGC and ALC, no trick, really complying with CE directives.
