Page 3: Introduction
The 4015 ATU features a memory facility that stores the configuration required to tune to a frequency. On any subsequent use of that frequency, the 4015 reconfigures to the stored settings in, typically, less than 130 milliseconds. Fol- lowing initial tuning, the antenna’s VSWR is monitored. -
Page 4: Installation
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. -
Page 5: Antenna
4015 MARINE AUTOMATIC ANTENNA TUNER Antenna On sailing vessels the antenna can either be an insulated backstay or a whip antenna mounted vertically, usually on the stern. Best performance will be achieved by using an insulated backstay as the radiating length will be longer than that available when using a whip. - Page 6 Tuner positions Good - High position Better - Mid position Best - Low position Antenna wire positions Best - Two-wire Better - Inverted L Good - Vertical inverted L Please contact Barrett Communications with your vessel’s specifications for addi- tional assistance.

Page 7: Transceiver And Tuner Mounting
4015 MARINE AUTOMATIC ANTENNA TUNER Transceiver and Tuner Mounting Select a suitable position in the vessel to mount the transceiver. It should be a position that is out of the weather and easily accessible to the operator, whilst as close as practical to the 13.8 V DC power source. -
Page 8: Ground (Earth) System
Ideally the vessel should be fitted with an external copper ground (earth) sheet, connected to the interior of the vessel by suitable stud or an ground (earth) plate (“E” plate Barrett P/N BCA91700) Should neither of these methods be available, acceptable ground points include stainless steel stanchion, through mast, through hull or a metal water tank. -
Page 9: Corrosion
When received, the Barrett 4015 automatic antenna tuner memory system will usually not have any pre-stored tuning information appropriate to your installation. To allow the 4015 to ‘learn’ its tuning information simply proceed from one channel to the next allowing the normal tune cycle to take place. -
