FEATURES
* Troidal core type directional coupler assures flat fre-
quency response, eliminating the need for calibration
tables; calculations and handling knob of frequency
variation.
* Frequencies are practically flat over the range of 1.8
MHz to 200MHz in full scale of meter even in 1.9MHz
or 3.5MHz band, thus permitting measurements of
various functions in low bands with small power.
* Radiant power (RAD) indicator (Pat. pending) to in-
dicate forward power minus refrection power, is
included in the instrument. This is particularly useful
to prevent trouble which might occur during matching
work, and facilitates monitoring and adjustments of
transm itter.
* Aritenna selector switch is self-contained to select
either of two antennas for quick QSY. If a dummy
load is connected instead of antenna, the instrument
functions as a terminal type power meter.
* Large sized, linear scale for easy and error-free read
ing of SWR and power.
