Standard External Antenna Installation
If the receiver must be located inside a control panel or
other enclosure, an external car antenna is required.
Mount the antenna onto a metal surface with the same
ground as the receiver circuit board. Remove any burrs
from the antenna mounting hole and scrape away any
paint which may insulate the antenna base from
making positive contact.
NOTE:
Improper installation of the antenna will cause
intermittent signal loss.
1. Drill a hole 14 mm (.56 in.) dia. through the
control panel or enclosure at the external car
antenna location.
2. Insert the connector base through the hole with
the antenna on the outside. Seat the base firmly
against the enclosure surface.
3. Assemble the antenna as shown below.
4. Screw the antenna pole onto the antenna base.
For RX-14 receivers:
1. Use M12 cable gland to feed antenna cable to
BNC antenna connector inside receiver.
2. Disconnect internal antenna from RF module
BNC connector and attach external BNC antenna
cable.
3. Bundle any excess antenna cable and secure
with tie wraps or equivalent.
For RX-20 receivers:
1. Remove the Miniflex antenna from the receiver
housing by unscrewing it from the antenna base.
2. Connect the external antenna cable to the
antenna base on the receiver housing.
3. Bundle any excess antenna cable and secure
with tie wraps or equivalent.
IMPORTANT:
DO NOT run the antenna cable with
power or control wiring. Intermittent signal loss will
result.
GainFlex Antenna Installation
Your application may require the use of a GainFlex
antenna. The GainFlex antenna can extend the range
of the radio remote control system up to 300 meters
(1000 ft.). It can also be used where a standard
antenna is difficult to mount. If you are not sure which
antenna is suitable for your application, please contact
Hetronic or your dealer.
When using a GainFlex antenna, there must be no
metal or conductive materials within 2 meters (6 feet)
of the antenna. This material will interfere with the
transmitter signal and cause intermittent signal loss.
For the best reception, the antenna should point
upward.
NOTE:
Improper installation of the antenna can cause
intermittent signal loss.
1. Secure the GainFlex antenna base to a mounting
surface with the tie wraps included. Mount the
antenna vertically with the base pointed upward.
2. Screw the GainFlex antenna pole onto the base.
For RX-14 receivers:
1. Use M12 cable gland to feed antenna cable to
BNC antenna connector inside receiver.
2. Disconnect internal antenna from RF module
BNC connector and attach external BNC antenna
cable.
3. Bundle any excess antenna cable and secure
with tie wraps or equivalent.
For RX-20 receivers:
1. Remove the Miniflex antenna from the receiver
housing by unscrewing it from the antenna base.
2. Connect the GainFlex antenna cable connector to
the existing antenna base on the receiver
housing.
3. Bundle any excess antenna cable and secure
with tie wraps or equivalent.
IMPORTANT:
DO NOT run the antenna cable with
power or control wiring. Intermittent signal loss will
result.
