Antenna Divider Installation Instructions
Installation Connections
1. Using rack mount brackets supplied, install the Sabine Antenna Divider into an EIA
standard cabinet (this step is optional).
2. Attach the two antennas supplied with your receiver to the A and B Antenna Input
Connectors on the back of the Antenna Divider. To improve reception, you can replace
the supplied antennas with Sabine Extension Antennas (UHF: SWAUEXT or VHF:
SWAVEXT).
3. Using the supplied cables, connect the #1 A and B Antenna Outputs on the Antenna
Divider to the corresponding Antenna A and B TNC connectors on your #1 Sabine
Wireless Receiver. Proceed in the same fashion for the remaining Sabine Wireless
units.
4. Plug the AC-to-DC Power Adapter cord into the DC Power Input Jack on the back
of the Antenna Divider. Plug the adapter into an appropriate AC power source (see
Caution #1 below).
5. Turn on Power switch.
General Installation Cautions
1. Power Supply: Be sure to plug your unit into an appropriate power source. Low
voltage (<12 Volt) will cause the unit not to function properly. High voltage (>18 volt),
or fluctuating voltage may damage the unit.
2. UHF/VHF Mixing: Do not mix UHF and VHF receivers on one Antenna Divider. For
UHF reception, use a Sabine SWA4U Antenna Divider. For VHF reception, use a
Sabine SWA4U Antenna Divider.
3. Antenna Shorting: Be careful not to allow the antenna to come in contact with metal
surfaces (antenna divider case, other wires, cables, etc.).
4. Receiver to Antenna Divider cables: Keep these cables as short as possible. It is
recommended to use the cables supplied with your Antenna Divider.
5. Extension Antenna cables: For best results, use high quality coaxial cable with a
50 Ohm impedance. Specifications will vary by cable manufacturer. For best
results, the cable attenuation should be no more than 6 dB per 100 feet (30 meters)
in the transmitter/receiver band. Examples of such cables are RG217/U for UHF and
RG58/U for VHF. The longer your cable, the more you can subtract from the 100-
meter range between transmitter and receiver antenna. A well-placed extension
antenna will eliminate trouble spots and generally improve overall performance of
the wireless.
