7. The straight-line distance ad is the square root
(
) of the result obtained in Step 6.
Example:
• Distance ab=40 feet; ab
2
= 40x40=1600.
• Distance bc=10 feet; bc
2
= 10x10=100.
• Distance cd=20 feet; cd
2
= 20x20=400.
• ac
2
= 1600+100=1700
• ad
2
= 1700+400=2100
• ad = 45.83’
Here, the straight-line distance ad is just under 46
feet, which is compatible with 50dB amplifier gain
as indicated in the previous table.
Note: Most calculators have a square
root (
) key.
Separate interior antennas based on the calcula-
tions shown in Section 3.5. You may mix and
match dome and directional antennas as needed
to obtain proper coverage throughout the build-
ing or area where you need to boost the signal.
If you are using a
Yagi exterior ant-
enna, you should
normally aim it away
from all interior
antennas regardless
of separation to pre-
vent oscillation.
CAUTION: SIGNAL OSCILLATION CAN
CAUSE RADIO INTERFERENCE WITH
CELLULAR TOWERS AND RESULT IN
CIVIL AND/OR CRIMINAL PENALTIES.
