Then, while the helper holds down the transmit key, walk
around and adjust the meter’s knob until the meter’s nee-
dle moves to 3 on the FIELD STRENGTH scale.
Notes:
• If you use a CB that has sideband modes (SSB), do not
select any of these modes. (Use only AM for field
strength measurements).
• If you have an amateur radio, select the continuous
wave (CW) or tuning mode to check the field strength.
4. Have the helper release the transmit key, then make a
change to your radio or antenna (such as adjusting the
antenna or transmitter or adding a new antenna).
5. When the change is completed, have the helper hold
down the transmit key again while you watch the meter’s
needle.
If the field strength reading is higher
, you have probably
improved the power output and efficiency of your radio
and antenna.
If the field strength reading is lower
, repeat
Steps 4 and 5.
Note: If you move the physical location, or change the
transmission direction, of your antenna, you might have to
recalibrate the meter and measure the field strength
again. See “Calibrating the Meter/Measuring Field
Strength” on Page 13.
