7.4 Using More than 4 Antennas
I
The JRL-2000F ean be operated with up to than 4 antennas eonneeted direetly to the amplifier.
However, by utilizing eommon, eommereially available antenna switehes, the JRL-2000F ean
be used with stored matehing data for more than 4 antennas.
For example, by using three
antenna switehes, 8 antennas may be eonneeted to the JRL-2000F as shown below.
The 8 antennas eonneeted 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
