DESCRIPTION

The AL-705 is a HF 40 to 10
meter (7 - 29.7) Magnetic
Loop antenna that is rated at
20W PEP SSB, 10W CW &
Digital.
Connect your equipment
Attach the feedline's PL259 to the SO239 on the
T-Connector in the center or the (small) coupling
loop, then connect the other end of the feedline to
your equipment.
Make adjustments to your Mic Gain settings
For all voice modes, adjust your equipment's Mic
Gain so your meter does not peak when
speaking, which will typically be a setting between
9 and 11. This will ensure you do not have a
distorted voice transmission by keeping the
antenna and equipment from being overdriven.
