6. When utilizing a mono band antenna, check before
operation that the antenna is identical with the transceiver
operating frequency. When inserting the coaxial switch
to either or both of the input and output sides of the
amplifier unit in order to operate two sets of transceivers
and antennas which have different frequencies, carefully
check the position of the coaxial switch.
7. Be sure to use a 50
Ω
coaxial cable for the various
connections. When the impedance differs as with a 75
Ω
cable, reflected waves will cause a mis-match. This
condition makes it difficult to achieve full power from
the amplifier and it may cause the RF power transistor to
be damaged.
8. When using a stabilized DC power supply, the output
voltage may rise to an abnormal level due to RF signal
intrusions. Therefore, use a power supply with sufficient
current capacity (7A or more) as well as a good
protective device for RF intrusions. If the power supply
malfunctions, discontinue operation by turning off the
power switch and make sure the connection of the
amplifier to the power supply is correct (a diagram is
shown on the following page.
9. The cord may be burned if the power supply is connected
in reverse polarity, especially if the power source is a
battery. Check the polarity well before connection. The
interior of this amplifier is protected from a reverse
polarity connection by a protection circuit.
