The Automatic Polarity Controller (APC) is designed to bridge
the gap between modern FTA satellite receivers and a feed
horn with servo controlled polarity (H/V) selection. The
modern FTA receiver changes voltage level (18V/13V dc) on the
coax to an lnbf in order to select between horizontal and
vertical polarity. The APC detects whether the FTA receiver
is sending 18V or 13V, and then the APC sends an appropriate
pulse signal to the feed horn servo to select the
corresponding polarity.
The APC is designed to work with Chaparral, ADL, HTS, Channel
Master, and other servo controlled feed horns. Each APC is
hand tested with a Chaparral feed horn servo to confirm
proper operation. It is user adjustable, so it can be
calibrated with your specific feed horn.
The APC can also be used as a manual polarity controller with
skew control without being hooked up to an FTA receiver. It
can be powered from either the FTA receiver or the included
9V wall transformer (if the transformer is not plugged in,
the APC automatically uses power from the receiver
connection). It has a magnetic base to keep it positioned on
a metal receiver enclosure.
NOTE: The "vertical" output voltage (about 13V dc)
from an FTA receiver may be too low for proper operation of
some LNBs. In that case, a power inserter (not supplied) may
be used between the receiver and the LNB to supply a higher
voltage for proper LNB operation.
I would also like to give Special Thanks to Randy K for building these units for the Free To Air Community!
