APPENDIX 3 — RF RANGE AND ANTENNA OPTIONS
Radio system operating range is dependent upon many factors. The Vaux remote sends radio signals
throughout the house to be picked up by the Aris Controller. In order to obtain maximum range, the
location of the Controller is important. In some cases, installing the Controller on the second floor will
provide greater range than a ground floor installation. Reception is also affected by atmospheric
conditions, and by metal construction which acts to shield radio signals (for example, aluminum siding,
insulation foil backing, and heating ducts). Of course, you can't easily relocate your audio/video
components to suit Aris reception, but you can keep in mind that a higher installation site for your Aris
Controller would be desirable. Also, try to keep the Controller's Antenna Wire in a vertical position and away
from other cables and metal cabinets where possible.
Vaux's handheld RF Remote Controls transmit a radio command when a button is pressed; this command is
acted on when received by the Vaux Controller. The Controller contains the radio receiver and uses an
external antenna to pick up the RF commands (when discussing RF reception, we sometimes refer to the
Controller as the
Receiver
). Each button press sends three identical packets of data; the Controller must see
two identical packets in order to consider it a valid transmission. Additionally, a security ID code must
match (much like setting an ID switch in your garage door opener). Therefore, it is virtually impossible for
anything other than your Vaux Remote Control to invoke a command in your Vaux Controller.
Base-Loaded Coax Antenna (Vaux Model ANT-2)
The Base-Loaded Coax Antenna is the standard antenna provided with the Aris Controller. It consists of a
short length of 75-ohm coax, a 25” antenna wire, and a loading coil to tune the wire. This antenna
generally plugs directly into the F connector antenna input of the Aris Controller, and is designed to simply
hang down (or to be tacked up) behind the cabinet. It may also be extended from the chassis with a coax
cable. The Base-Loaded Coax Antenna (the components marked with * below) is available from Vaux (Model
ANT-2).
Radio reception range when using the Base-Loaded Coax Antenna, is:
• Open-field: 250 ft. typical
• In-house (wood-frame construction): 125 ft. typical
• Typically covers up to 5000 sq. ft. homes.
IMPORTANT:
With a more efficient antenna, and/or an antenna preamp, you can increase the range to
cover larger installations.
