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. Moving the antenna one way or another just a few feet can make a tremendous difference in the success of the antenna installation. WARNING – Installation of this product near power lines is dangerous. For your safety, keep ladder and antenna away from power lines. Contact may cause electrocution. Overview DTV is a little different than analogTV.With analogTV peak signal strength was the most important factor for good reception and creating a good picture.With DTV peak signal strength is not the most important factor for good reception. This means that our old methods for finding a location and aiming a TV antenna will not give us the best results for DTV. In choosing a permanent location for our DTV antenna we want to look at a couple of mounting locations.There are two methods for testing for the best antenna location: 1. Terrestrial Digital receivers internal signal strength indicator. 2. Conventional Analog TV pointing method. Tip: Do not use a convention signal strength meter for installing a DTV antenna. Chances are this will give you false information and cause the antenna not to work reliably. Severe ghosting is the number one reason for DTV reception problems. Most severe ghosting occurs in locations where there is plenty of signal strength. A conventional signal strength meter will find this location. 5 EN DTV Tuner Signal Strength DTV Tuner Signal Strength Indicator If your DTV set top box or DTV tuner in your TV has a signal strength indicator (refer to that components user manual) you can utilize this feature for selecting a location for installation and aiming the antenna. 1. Locate antenna in a high location with as few obstructions in front of, behind, or to the sides of the antenna as possible. Optimally the antenna needs to be at least 30 feet above the ground pointed directly in the “line of sight” of the broadcast antenna (Line of sight means that there are not any obstructions between the broadcast and receiving antenna such as buildings,water towers, mountains or trees. Line of sight does not mean you need to be able to see the broadcast antenna with your eye) If you are able to achieve this “line of site installation and do not have severe multi-path problems such as in a very dense high rise area, you will in most cases receive a good stable DTV and Analog TV picture. 2. Connect the antenna to your DTV tuner with a good quality transmission line. 3. Slowly rotate antenna on mounting mast in both directions until the highest signal strength is achieved on the DTV tuner. Check all DTV channels to make sure the signal is good on all channels you desire to receive from the DTV broadcast tower that you are pointing at.If you have two DTV broadcast towers in two distinct directions and are not able to receive all DTV stations broadcasting in your area install the antenna with a rotor. 4. Watch DTV channel for a few minutes to make sure picture is consistently stable without freezing, disappearing or breaking up. If picture is stable, securely mount antenna per enclosed mounting instructions. 5. Forbestresults,do not run signal through diplexersorsplitters,run new RG6 co...
