2.7.3 Testing
After running the transmission line and fastening it in place, connect the antenna end of
the transmission line to the antenna feed line, using a short coaxial jumper and a double
female barrel adapter. Connect the radio end of the transmission line to a wattmeter
(with appropriate frequency and power rating), using the radio feed line and another
coaxial jumper (see Figure 2-19). Power-up the radio.
Observe forward power, and check that reverse power is negligible. Turn off power to
the radio.
Exchange the wattmeter with the barrel adapter and coaxial jumper at the antenna end
of the transmission line. Power-up the radio.
Observe forward power to the antenna, and verify that power loss in the transmission
line is within system specifications. Verify that reflected power from the antenna is
negligible. Reflected power should be less than 5% of the forward value, and in most
cases will be significantly less.
