WARNING
Whenever a rigger is on the tower in the area of the antenna, shut off
the signal and lock it off so that it cannot be turned on accidentally. RF
emissions at close range are hazardous.
NOTE
The Versa2une does not require pressurization or purging.
Optimize VSWR.
(
Figure 45
) Apply a low-power signal to the antenna and read reflected power
(VSWR). VSWR should be below 1.2:1.
Figure 45. Apply the signal
Adjust to minimize
reflected power if
necessary.
a. Loosen one jam nut on one arm of one antenna element and lengthen that
arm by 10 mm (3/8"). With personnel clear, check VSWR again.
b. If the VSWR (reflected power) has increased, return that arm to its original
setting. Then shorten ALL arms by 3 mm (1/8").
c. If the VSWR has decreased, return that arm to its original setting. Then
lengthen ALL arms by 3 mm (1/8").
d. Repeat steps a - c until VSWR is below 1.2:1.
e. Secure all the arms by tightening their jam nuts.
Operate.
Once the antenna has been installed and VSWR has been confirmed, simply
apply the transmitter signal. Don’t exceed the rated power of the antenna.
