With an extra SO-239 on the rear panel and a coax jumper, the amp
manufacturer could provide a "loop-thru" for an external power
attenuator. This would allow the user
to tailor the drive requirements of the amplifier to their transceiver
output characteristics by selecting the appropriate attenuator value.
