A Drake matching network is a worthwhile addition
to any amateur station where peak performance is desired. Basically identical,
except for power handling capabilities, the MN-4 and MN-2000 enable feed line
SWR’s of 5:1 to be matched to the transmitter. If input impedance is purely
resistive, even higher SWR’s can be handled. Besides presenting a 50 ohm load
to the transmitter, the Matching Network’s built in RF wattmeter allows
accurate and continuous power measurement and VSWR indication. The advanced
wattmeter circuitry yields frequency-insensitive readings from 2 to 30 MHz, and
accuracy until now obtainable only in expensive watt meters.
