Transformer Connections
The power transformer of the AL-800H has fourteen different voltages available on the primary and is rated
at full power with supply frequencies of 50 to 60 Hz and voltages above 200 volts. The JUMPER
CONNECTIONS chart below indicates the proper placement of jumpers for various power line voltages.

WARNING:
The AL-800H requires different back panel fuses for various line voltages. Use the
fuse listed in the JUMPER CONNECTIONS chart for maximum protection.
Interconnections
1. Connect the exciter's RF output to the
"RF IN"
connector on the rear of the AL-800H with 50 ohm
coax. Use any good quality 50 ohm cable long enough to connect the amplifier to the exciter. This
amplifier connection uses a standard SO-239 female that mates with a PL-259 male connector on the
cable.
2. Connect the existing station antenna system to the
"RF OUT"
connector on the rear of the AL-800H
with RG-8 type coax. This amplifier connection uses a SO-239 female that mates with a PL-259
connector on the cable.
