FOR YOUR SAFETY, KEEP LADDER AND ANTENNA AWAY FROM POWER LINES. CONTACT MAY CAUSE ELECTROCUTION Antenna Grounding and Safety Warning 1. Outdoor antennas and lead-in conductors from antenna to a building, should not cross over open conductors of electric light of power circuits.They should be kept away from all circuits to avoid the possibility of accidental contact. 2. Each conductor of a lead-in from an outdoor antenna should be connected with an antenna discharge unit. Antenna discharge units (or Lightning Arrestors) should be located outside the building or inside the building between the point of entrance of the lead-in and the TV, and as near as practical to the entrance of the conductors to the building. About the Design of Your Antenna The design process of this antenna began in the very early days of DTV transmission, largely because of frustration with the selection of antennas on the mar- ket.The old antennas were all legacy technology from the 1950s.Popular thinking of the early days of DTV transmitting was “radio waves have not changed so why should we use different antennas for DTV?” Radio waves have not changed but our transmission system and performance expectations have. We designed this antenna to be an integral part of the DTV transmission and reception chain. It is designed to maximize the strengths and minimize the weakness of the new ATSC system. It was designed to work with the DTV tuner and capture a more stable signal so the DTV tuner can do its job with a minimum of effort and create a razor sharp and stable picture on your DTV.This antenna was not designed by simulated theoretical physics; it was designed to work with the physics of the real world,the real world of changing weather,cities and mountains.This antenna will work in areas where others completely fail or provide marginal results with part time reception. 3 EN Assembly and installation fig. 3 fig. 4 fig.6 fig. 5 Assembly and installation instructions Before assembling the antenna, take a moment to familiarize yourself with the antennas’ construction. Notice that the boom of the antenna has a top and bottom. The horizontal elements are mounted to the top side of the boom. The reflector on the other hand, does not have a specific top or bottom. 1. Extend the folded drive element by carefully folding the “wings” outward so they are at 90 degrees to the boom. (fig.3) 2. Attach Transformer to bottom studs of drive elements with wing nuts and washers. (fig.4) 3. Slide the reflector screen onto the boom from the rear until the screw holes of the screen bracket line up with the holes on the top and bottom of the boom.Attach the screen to the boom using two (2) 1-1/2” bolts, lockwashers and wing nuts. Tip: To make it easier to fit when sliding the screen onto the boom, squeeze the top and bottom of the screen towards each other. 4. Insert end caps at end of boom (fig. 5). 5. Attach the antenna to the mast: Assemble U-bolt to cross piece. Attach U- bolt assembly loosely to antenna, using saddle, lockwashers and nuts. insert mast through U-bolt.Tighten nuts securely (fig.5) (Mast sold separately). 6. Connect 2 mast sections as shown in figure 6 (included in SDV9201K only) ENAiming the Antenna 7. Connect a good quality RG-6 coaxial cable to the transformer. Slide the weatherproof boot over the connection firmly until it seals (fig.7) (Cable sold separately) fig. 7 fig. 8 8. Attach cable standoff to mast as shown in figure 8 (included in SDV9201K only) Aiming the Antenna Before permanently mounting the antenna for digital television (DTV) reception it is a good idea to perform a quick sight survey to find the spot with the best signal.
