Resumen del manual


The mount can be positioned manually or by using a crane; however, Andrew recommends that this procedure be performed using a crane to ensure speed and ease of installation. Figure 3-2: Crate Unpacking As stated previously, the pedestal ground mount installation process can be conducted manually or by using a crane. The following steps provide the necessary procedures for installing the ground mount assembly using a crane. 16 Installation Procedures Step 1 Step 2 Step 3 Step 4 Carefully remove the ground mount assembly (P/N 208800 - motorizable or P/N 202680-2 manual) from the packing crate. Leave the steel strapping intact to avoid disengagement of the panning frame from the square-tube weldment during the ground mount installation. Securely attach the crane to the ground mount assembly using a sling, and carefully raise the entire ground mount as shown in Figure 3-3. Figure 3-3: Raising Ground Mount Assembly Align the ground mount assembly directly over the anchor bolts (P/N 203314 - manual or P/N 203666 - motorizable), which should have been previously mounted in the foundation pad. NOTE: Ground mount positioning on the foundation is dependent upon predetermined azimuth viewing requirements. The ground mount assembly arm should be positioned opposite the satellite requirement. If your site is in the Northern hemisphere, your satellite will be located in the South. If your site is in the Southern hemisphere, your satellite will be located in the North. Lower the ground mount assembly onto the anchor bolts with the corresponding hole pattern. 17 Installation Procedures Step 5 Step 6 Step 7 Attach the ground mount assembly to the eight corresponding anchor bolts using a 3/4 inch flat washer and 2-3/4 inch hex nuts as shown in Figure 3-4a. One 3/4 inch hex nut is supplied with the anchor bolt kit and the second 3/4 inch hex nut is supplied with the antenna. Figure 3-4a: Ground Mount Assembly Base Hardware Remove the steel strapping from the ground mount assembly. Tighten the foundation hardware using the A-325 tensioning procedure. Figure 3-4b shows the ground mount assembly attached to the foundation.

If a crane is not available, the following steps provide the procedure for installing the ground mount assembly without a crane. Carefully remove the ground mount assembly (P/N 208800-motorizable or P/N 2026802- manual) from the packing crate. Leave the steel strapping intact to avoid disengagement of the panning frame from the square-tube weldment during the ground mount installation. Lay the ground mount assembly on its side, in line with the anchor bolts (P/N 203314manual or P/N 203666-motorizable) as shown in Figure 3-5. NOTE: Ground mount positioning on the foundation is dependent upon predetermined azimuth viewing requirements. The ground mount assembly panning-frame arm should be opposite of the satellite requirement. If your site is in the Northern hemisphere, your satellite will be located in the South. If your site is in the Southern hemisphere, your satellite will be located in the North. Figure 3-5: Ground Mount Assembly Alignment with Anchor Bolts 19 Installation Procedures Lift the ground mount assembly into an upright position. In the absence of a crane, it is recommended that a minimum of two people assist in the lifting of the mount assembly as shown in Figure 3-6a and Figure 3-6b. Step 3 Figure 3-6a: Manual Lift Figure 3-6b: Manual Lift 20 Installation Procedures Step 4 Step 5 Step 6 Figure 3-7: Mount Alignment/Adjustment NOTE: You may need to adjust the mount when lifting it to ensure that the anchor bolts are aligned directly underneath the base of the ground mount assembly as shown in Figure 3-7. Attach the ground mount assembly to the eight corresponding anchor bolts using a 3/4 inch flat washer and 2-3/4 inch hex nuts as shown in Figure 3-3a. NOTE: Ground mount positioning on the foundation is dependent upon predetermined azimuth viewing requirements. The ground mount assembly arm should be opposite the satellite requirement. If your site is in the Northern hemisphere, your satellite will be located in the South. If your site is in the Southern hemisphere, your satellite will be located in the North. Remove the steel strapping from the ground mount assembly. Tighten the foundation hardware using the A-325 tensioning procedure. Figure 3-8a illustrates the ground mount assembly attached to the foundation. Figure 3-8a: Ground Mount Assembly Base Hardware 21 Installation Procedures Motorizable Pedestal Ground Mount Assembly Step 1 Step 2 Step 3 Step 4 The ground mount assembly enables 180° positioning for selected azimuth viewing. Azimuth range coverage is ±90° divided into three 120° continuous ranges with 30° overlap. Elevat...
