4015 MARINE AUTOMATIC ANTENNA TUNER
Installation
The Barrett 4015 automatic antenna tuner is designed for use in land base sta-
tion and maritime HF services. Primarily designed for operation with end-fed
unbalanced antennas such as whips and long wires, the tuner is built in a water-
proof impact resistant, moulded ABS plastic enclosure.
Antenna Selection
The 4015 automatic antenna tuner will operate into almost any end-fed antenna
with a length exceeding 2.5 metres, providing an effective ground (earth) is
used.
The antenna efficiency will be proportional to the length of the antenna and
will be maximum when the length of the antenna approaches ¼ wavelength.
It is advisable to limit the wire antenna to ¼ or ¾ wavelength at the highest
frequency to be used.
