Mounting the Preamplifier to the Loop Antenna L-Bracket
The preamplifier is mounted to the L-bracket that is attached to the loop antenna
using the included saddle clamp and mounting hardware which also connects the
antenna to a short 1-1/4” diameter customer supplied mast (that would then normally
go into the rotator). Nylon shoulder-washers and nylon flat washers are used to
electrically isolate the metal case of the preamplifier from the mounting pole as shown below. This
is required to avoid ground loops. The upper saddle clamp uses the regular hardware (serrated
flange hex nut) as shown in the pictures below. The use of Jet-Lube SS-30 anti-seize (
JTL-12555
)
is recommended for all hardware to avoid galling.
The loop antenna and the preamplifier have small weep holes in that face downward to drain any
condensation that may accumulate internally. A one foot RG-6 jumper cable is supplied to connect
the output of the loop antenna to the input of the preamplifier. When looping this RG-6 jumper,
ensure the loop does not rub against the saddle clamp hardware.
