Package Contents NOTE: Antennas and cables may be different than shown depending on your kit configuration Pg. 4 Outside Antenna Inside Antenna Booster Extension Cable Power Supply Optional Parts Omni Directional Antennas Co-Ax Cables Antenna Pole Mount Kit RF Splitter/Power DividerCo-Ax Adapters Antenna and Booster Installation a) Location: There are three choices. fig. 2, 3, 4. The choice of donor antenna location depends on the signal strength at the donor antenna location. Use your phone to determine if signal at your chosen location is adequate. Better signal level at the donor antenna location equals larger indoor coverage area. b) Directional Donor Antenna: if using a directional donor antenna supplied in the kit (Part# SEMD1), point the antenna toward the desired tower. If the loca- tion of the desired tower is not known, initiate a phone call and use the signal indicator on your phone after the booster is operational, while turning the donor antenna, to determine optimum donor antenna direction for maximum signal strength. c) Omni-directional Donor Antenna: if using an omni-directional donor antenna, it is recommended that it is placed as far as possible from the inside antenna, usually, ‘outside pole mount’ is recommended (Fig. 3). Use of omni-directional antennas will require substantial separation distance compared to directional antennas. Fig. 1 Donor Antenna: (outdoor signal antenna) Distribution Antenna: (indoor signal antenna) Connection and Start Procedure: Amplifier/Booster Location: Install the repeater in a location that has proper ventilation, away from excessive heat and moisture. a) Location: There are three choices. fig. 2, 3, 4. The choice of donor antenna location depends on the area to be covered. b) Directional Distribution Antenna: it is recommended that directional antennas are oriented in a fashion that is back to back of each other Fig. 1 c) Omni-directional Distribution Antenna: it is important that omni-directional antennas are separated as far apart as possible from each other. Use of omni-directional an- tennas will require substantial separation distance compared to directional antennas. Fig. 1 d) Splitting Indoor Signal: it is possible to use more than one indoor antenna to cover areas that are separated by walls or floors by using antenna splitters or power dividers, however splitters have a level of signal loss (3dB) and the added cable run will also have signal loss, therefore the coverage area will be diminished. As a general rule, if outside signal is good, splitting signal to more than one distribution antenna results in reasonable coverage. If outside signal is poor or marginal, splitting signal to more than one distribution antenna results in decreased coverage for both distribution antennas. Use only genuine SmoothTalker splitters. Contact your dealer or www.smoothtalker.com WARNING: Make sure all cables have a good connection and are connected to the corresponding antenna port on the Booster. DO NOT APPLY POWER or turn on the power switch on the Amplifier/Booster before all cables and antennas are connected. Antenna connections must be snug and hand tight, ‘Do Not Use Pliers or Wrench’. Connect the cable from outdoor antenna to RF port (antenna connector) labeled “Outdoor Antenna”. Connect cable from indoor antenna to RF port labeled “Indoor …
