SPECIAL OPERATIONS
7.4 Using More than 4 Antennas
The JRL-2000F can be operated with up to than
4
antennas connected directly to the amplifier.
However, by utilizing common, commercially available antenna switches, the JRL-2000F can
be used with stored matching data for more than 4 antennas. For example, by using three
antenna switches, 8 antennas may be connected to the JRL-2000F as shown below.
The 8 antennas connected are:
Antenna A: For the 1.9 MHz band.
Antenna B: For the 3.5 MHz band.
Antenna C: For the 7 MHz band.
Antenna D: For the 10 MHz band.
Antenna E:
Multi-band antenna for the 14 and 21 MHz bands.
Antenna F: For the 14 MHz band
Antenna G: Multi-band antenna for the 21 and 28 MHz bands.
Antenna H: Multi-band antenna for the 7, 21 and 28 MHz bands
