Connection To Antenna & Power Supply; A Word About Grounding - Ten-Tec Argonaut VI 539 User Manual

1.4. Connection to Antenna &
Power Supply
The Argonaut VI is designed for use with any
antenna system providing a 50 Ohm resistive
impedance at the desired operating frequency.
Every effort should be made to ensure the
impedance of the antenna system is as close
as possible to the specified 50-Ohm value.
Note: that the "G5RV" type antenna and
some Windom's do not provide 50-Ohm
impedance on all HF Amateur bands, and an
external wide-range antenna coupler will be
needed. Any antenna to be used with the
Argonaut VI must, ultimately, be fed with 50
Ohm coaxial cable.
The Argonaut VI transceiver requires a
source of well-filtered and regulated DC
voltage. The supply voltage for the Argonaut
VI is 13.8 Vdc nominal +/- 15% to allow for
mobile and battery operation.
source must be capable of supplying 5-7
amperes continuous duty. We recommend
using the included DC power cable (P/N
86095).
Note: Always enable the power source first
and then the transceiver. If a generator or
battery connected to a charger is used to
supply the DC source, always turn off the
transceiver before starting or shutting off the
DC source equipment.
devices often generate large voltage spikes
that can damage the transceiver.

1.5. A word about grounding

A good ground system is essential for
optimum operation of any HF transmitter.
The best solution is to connect all the station
equipment to a single ground connection.
Refer to Local and National Electrical Codes
before making any connections with the
Argonaut VI. Another source of information
on grounding can be found in the ARRL
Handbook.
A good ground system can contribute to the
station efficiency in a number of ways
including minimizing the possibility of
electrical shock, and minimizing RF currents
flowing on the shield of the coax cable
causing interference to electrical equipment
and transceiver accessories.
It is critical that the power supply, the
Argonaut VI, and other equipment in the
station be properly grounded to an Earth
ground. Improper grounding can lead to
various issues, including RFI, ground loops,
or even death. Therefore it is extremely
important to refer to the Local and National
Electrical Codes and ARRL Handbook with
regards to grounding.
