What is the purpose of antenna tuning unit?

An antenna tuning unit, ATU or antenna tuner is an item consisting of inductors and capacitors that is used to tune an antenna so that it matches the feeder and reduces the SWR.

How does a ATU work?

How does an ATU work? An aerobic treatment system uses several chambers to treat wastewater in varying stages using biological processes. The aeration chamber : the partially treated wastewater from the primary chamber is mixed with air to assist bacteria to treat it further.

What is antenna base tuner?

An antenna tuner (and any of the names in the list below) is a device that is inserted between a radio transmitter and its antenna; when properly adjusted (tuned) it improves power transfer by matching the impedance of the radio to the impedance of the antenna, or the feedline which connects the antenna to the …

Do antenna tuners work?

The antenna tuner does not reduce the portion of signal lost in the transmission line. The antenna tuner DOES NOT improve the radiation efficiency of an antenna. Compromise antennas are still compromises, and poor antennas are still poor antennas.

What is an ATU tank?

Aerobic Treatment Units (ATUs) are similar to standard septic systems in that they use natural processes to treat wastewater. But unlike conventional systems, ATUs also use oxygen to break down organic matter, much the same as municipal wastewater treatment systems, but in a scaled-down version.

How much is an ATU?
