|Yaesu FC707 Aerial Antenna Tuner
options for the FT-707 include the aerial tuner unit FC-707 Antenna Coupler.
FP-707 AC Power Supply, which provides
the 13.3 volts DC required by the FT-707.
The FC-707 is an ultra-compact antenna tuner for the FT-707 transceiver.
Designed for operation on the 80 through 10
meter amateur bands, the FC-707 will provide a 50 ohm load to the transceiver when the feed point impedance of the antenna system is within the range 10 ohms to 250 ohms.
The FC-707 includes a built-in SWR and power meter, calibrated in 15 watt and 150 watt scales.
Also included is a 50 ohm dummy load, which may be selected instead of the antenna for preliminary coupler adjustments.
A THRU position of the bandswitch also allows the antenna to be connected directly to the transceiver, bypassing the tuner.
The matching function it performs means your transmitter will always “see” the resistive termination it was designed for.
The inherent selectivity of the FC-707 matching circuitry helps attenuate harmonics,
thus reducing harmonic-related TVI or out-of-band emissions.
