The dipole antenna consists of an active section and a lead-in section (see illustration on previous page). 2) Position the active section of the dipole antenna against a wall or along a flat surface of a non-metallic piece of furniture. Keep the active section of the dipole as straight as possible. Use thumbtacks or brads to secure the ends and the middle of the active section. 3) Connect the dipole antenna to the SoundWorks Radio 820HD by pushing the connector plug onto the FM antenna input. You can coil excess length of the lead-in section, then secure it with twist ties or tape. Note: The active section of the dipole antenna can be positioned horizontally or vertically. Placing the dipole antenna on an outside wall improves reception. The active section of the dipole antenna can also be positioned along a baseboard. Try a different placements and orientations of the active section to determine the best overall reception. Dipole Antenna Placement -2 Telescoping Whip Antenna a) b) The telescoping whip antenna provides good reception and can be easily adjusted. With adjustment factored in, it may perform the best of the three antennas. Once properly installed, the telescoping whip antenna will remain at any position you place it. To Install: a) Push the end of the antenna with the nut onto the FM connector. b) Slip the supplied wrench around the antenna and slip it up against the nut end of the whip antenna. The wrench c) d) flanges will be close to touching the back of the radio when you have successfully slipped it onto the antenna nut. c) Tighten the antenna nut securely. d) Remove the wrench, then push the antenna upright. Extend the whip antenna, then adjust for best reception on a particular station, as required. Note: For FM stations below 94 mHz, the antenna will always perform best if fully extended. Stations above 98 mHz may benefit from a reduction in length of up to 2-3 inches. -3 Wire Antenna 1) If all the desired FM stations have strong signal strength, the wire antenna can be used. It is the easiest of the three antennas to install and conceal. 2) Connect the wire antenna to the SoundWorks Radio 820HD by pushing the connector plug onto the FM antenna input. 3) The wire antenna can work well simply hanging down from the back of a desk or bookcase. Experiment with the position of the antenna wire, keeping it as straight and extended as possible. If you find a single position for the antenna that receives all stations well, tape it in place. Reposition the antenna as required to get the best signal for the desired station. -4 Two Orientations for the Wire Antenna Run the wire antenna along the edge of a table or just underneath the edge of the table. 1. 2. If there is a wall behind the radio, let the antenna hang straight down. AM Antenna 1) 2) 3) 4) Identify the AM Antenna. Fold the base as shown. Snap the tab on the loop into the slot in the base to complete the AM Antenna assembly. Be careful not to pinch the connecting wire. The finished antenna will stand upright, as shown. 5) Insert the AM Antenna plug into the AM antenna input, which is directly underneath the FM antenna input. 6) Position the AM antenna 8 inches away from AC power lines or equipment to minimize AM interference. The AM Antenna is mildly directional, so rotate it to find the best signal for each AM station. A single position can 2)1) 3) 4) often be found that works well with all AM stations of interest. 5) -5 Other Antenna Options The FM antennas and the AM antenna provided with the SoundWorks Radio 820HD will work well in most locations that get adequate FM and AM reception on conventional radio receivers. But there may an FM or AM station of interest where reception is marginal. To improve reception in marginal cases, re-positioning the antenna or using a larger antenna (or both) are the only reliable ways of improving reception. In this section, some suggestions for improved, user-supplied FM and AM antennas are made. A Note About Connecting A User-Supplied FM Antenna The SoundWorksRadioFM antenna input is an“F” connector socket. For easy connection, an user supplied FM antenna or coax cable should have a push-on “F” connector plug. Most retail FM and TV antenna products come with a screw-on “F” connector plug. To use one of these products, obtain a “screwon to push-on” adapterplugforan“F” connector Thispartis availab...
