| The switch box is where the antennas are connected and
where the coaxial cable that goes to the station. It is
designed to be installed externally near the antennas and
don´t need housed. |

The remote is the equipment where the
antenna selections are made and some configurations that
the system allows. It has 5 illuminated buttons, 4 for
the selection of antennas and one to aid in programming.
The antenna selection keys work on the ON / OFF mode,
ie pres once turn on, press again turn off. So it is easy
to control which of antennas you want to use at a certain
time. The combination of antennas for the transmission
and reception can be performed independently quickly and
easily. As an example, we can program the system to transmit
using antennas 1, 2 and 4 with and receive using antennas
2 and 3. The system is managed and supervised by a microcontroller
that has an internal software designed to meet the various
system functions and easy operation

In some installations, especially those
designed for contests, is very frequent found more than
one shack and more than one stack system. All control
boxes can be interconnected so that any remote can command
any switch box. In this case each shack would have one
remote that will operate on the band in use, ie, any remote
may control any one switch box without the need to exchange
any cabling.
The "Four Stack II" system from
Hamplus is manufactured for maximum power of 3000 Watts
ready for 1.8 to 30MHz.

The connections between components
of the Four Stack system are quite simple. A control cable
follows the remote control to switch box. The Hamplus
can supply this cable with connectors already mounted
at the desired length. In installations of multiple stacked
systems, the remote are connected together forming a communications
network by means of cables with connectors type P2. The
system needs to be powered by a 13.8 Volts connector that
exists on the remote control.
