HG-1 WR REMOTE LOOP TUNED MLA
Outdoor deployable
This remote is designed for harsher outdoor and fixed installations. It is
a durable, easy-to-use, remote tuner upgrade to your existing HG-1 MLA
using its radiation and induction loops and mast. It features end-of-cap
travel limit switches for long life. It uses the new HG-2 universal
controller. To maximize reliability found in the harsher environmental
conditions outdoors, this remote tuner uses a lower RPM motor and no
reduction gear. For this reason, there is a shallow learning curve to get
used to remote tuning. SWR is as low as the manually tuned HD-1 which
uses the identical tuning capacitor. We recommend, for convenient and
quick tuning to lowest SWR, using an auto tuner, such as those found in
the KX2 or similar transceivers.
TUNING WITH THE HG-2 CONTROLLER
(HG-1 WR Remote Tuner)
1.
Make sure the HG-1 MLA is placed in an obstruction free
area.
2.
Connect both ends of the supplied cable (common CAT-6
cable) to the motor assembly and controller.
3.
If possible, turn the receiver AGC off or set it to slow; bypass
any external or automatic antenna tuner and set the mode to
CW (it has the lowest controller QRM noise).
4.
Note: Applies to HG-1 WR REMOTE LOOP TUNER.
The HG-1
WR uses limit switches. So current sampling is used to
indicate the motor is powered on. CW and CCW limits are
indicated when the red LED limit indicator extinguishes.
5.
Turn the HG-2 Remote Controller to SBY (on)
and set the RATE control to a mid-range setting.
6.
Using the red UP or green DOWN buttons, tune
for a peak receive signal (use your ears or the S
meter). The maximum peak will be brief, but
obvious. You may have to momentarily push the
UP or DOWN buttons to get close.
7.
Once you receive an obvious peak signal, reduce the Rate control to about 1/3 and alternately make
small adjustments by briefly tapping the Up or Down buttons for the strongest peak signal.
8.
Note, when checking SWR, transmit a low power carrier. You should be able to achieve an SWR of 3:1 or
better. Once you achieve 3:1 or better, use an external or built-in auto tuner to touch up the SWR. You
should easily achieve an SWR of 1:1.5 or better.
9.
Set the receiver to the desired mode and turn the HG-2 Remote Controller off.
The red LED limit indicator will stay on
indicating the motor is powered during
capacitor turning and turn off when reaching
the CCW or CW limits, alerting the operator to
change tuning direction (The silk-screened
markings do not apply).
