1KW FAST-TUNE
HF ANTENNA COUPLER
RF-2601
FEATURES
> A rugged shipboard qualied
high power antenna coupler
The RF-2601 Antenna Coupler is designed specically for applications where
fast frequency change is necessary, such as those incorporating automatic link
establishment. It will operate continuously under the most severe environmental
conditions in vehicular, transportable, shipboard, and xedstation applications.
The RF-2601 efciently and rapidly matches the output of 1 kW transmitters and
transceivers to a wide variety of whip, dipole, and long-wire antennas over the
frequency range of 1.6 to 30 MHz. Upon keying the associated transmitter on a
new frequency, tuning occurs typically in 75 ms using previously stored (memorized)
tuning information. Emissions are minimized during memory tuning by limiting
actual on-the-air time to less than 30 ms.
The coupler is designed for direct interface with the RF-1140 1kW HF-ISB Transmitter
Series and RF-1145 1kW Transceiver System and can be remoted up to 500 feet from
the transmitter or transceiver.
The RF-2601 provides extensive automatic monitoring of parameters during normal
operation and also incorporates comprehensive operator-initiated static and transmit
BIT. If a fault condition should arise, the processor-controlled BIT quickly identies the
source of the problem to the replaceable module level or lower, speeding mean time
to repair.
