Detailed instructions for use are in the User's Guide.
[. . . ] If you claim a missing part, you will be asked for the weight verification label. There is a master parts list on page 2.
LOCATION
Location of the antenna is very important. [. . . ] Cushcraft offers several different models, such as LAC-1, LAC-2 and the LAC-4 series.
ASSEMBLY
Assemble your antenna by following the directions and illustrations in steps 1 through 5. After the antenna is completely assembled, verify dimensions and element spacings for accuracy. Then, return to the section below for final tuning.
TUNING PROCEDURE
The A144-11 does not normally require tuning after assembly. However, if you wish to check the VSWR before installation, please observe the following procedures. To prevent detuning the antenna, it should be tuned in place or at least 7 feet (2. 1 m) above ground and clear of surrounding objects. Keep all metal obstructions such as guy wires and other antennas at least 7 feet (2. 1 m) away since they will nullify any adjustment and degraded performance will result. Run the coax cable from your transmitter to the area in which the antenna is going to be tested. Connect a short length of cable [10 ft (3 m) or less] from the VSWR bridge to the antenna. When you read VSWR, be sure you move far enough away from the antenna so that your body does not effect the reading. If it is high, move the tuning strap by 1/4" (. 6 cm) in one direction and check the VSWR. If the VSWR improves, then continue moving the tuning strap in the same direction. If the VSWR deteriorates then move the tuning strap in the opposite direction. [. . . ] (13
