4.4. Operation with an External Antenna Tuner
At antenna SWR over 1.5:1, it is advisable you use an external ACOM tuner.
The ACOM 04AT Remote Automatic Antenna Tuner and Switch (see Figure 4-1 | ACOM 04AT tuner mounting
possibilities) and ACOM 06AT Automatic Antenna Tuner and Switch (see Figure 4-2 | ACOM 06AT antenna tuner
and switch (shown near 500S amplifier)) are designed to work with our transistor (solid state) amplifier series and
can be connected to the RF OUTPUT 1 of ACOM 500S as described in Sections 2.4.e) RF OUTPUT 1 connector
and 4.3 Antenna Change.
ACOM 04AT and 06AT tune antennas having SWR up to 3:1 automatically, thus providing an optimum load for
the amplifier within 5 seconds with improved harmonic suppression at that. The four-way antenna switch is
controlled automatically or manually from the amplifier front panel.
The ACOM 04AT can be installed both in the shack and in a remote location (even out in the open, close to the
antennas). It can be distanced up to 100 m (330 ft) from the amplifier, using a single coaxial cable.

ACOM 06AT tuner is designed for indoor use only! It can be located up to 100 m (330 ft) away from the amplifier,
using a single coaxial cable.
