This power amplifier is designed
to be used with our 12-Watt Variable power transmitter, or 12-Watt
Power amplifier. As with all our power amplifiers this unit is
completely broadband and does not require any tuning by the user.
Power supply requirements are easy
to fulfil, being 13.8V @ 6 Amps, which can be provided by a mains
power supply or vehicle battery. The front panel LEDs indicate
at a glance the presence of DC, RF input and RF output.
When RF input is absent the DC to
the Power amplifier shuts down automatically, conserving power.
This robust unit is protected from DC over-current using a high
powered mosfet and will never consume more than 5.75 Amps, regardless
of drive level or SWR mismatch, e.g. in the event of Antenna failure.
Thanks to the integrated fan cooling
system, this unit can run cool, even demanding applications, that
require 24/7 operation. On delivery the equipment is ready to
plug in and use with any suitable 50 Ohm antenna system such as
our Vertical 5/8 Wave, Single
Dipole or Stacked Dipole.
