| 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" 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.
