Step 1 – Install the mounting brackets to the metal base of the antenna as shown in Figure 1. CAUTION: The bracket must be secured to the antenna metal base. Attaching the brackets to the fiberglass mast will damage the antenna. Step 2 – Position the antenna in the desired installation location and mark the four bracket screw hole locations.
Choose a sturdy location, such as a wall stud, that can properly support the antenna. Step 3 – Drill pilot holes in the marked screw hole locations. Step 4 – Secure the external antenna with the provided four mounting screws. See Figure 2. Note: If installing on drywall or masonry, install the appropriate size and type screw anchors. Step 5 – Install the provided antenna surge protector to the antenna cable as shown in Figure 3. Note: The antenna cable that connects the external antenna to the Sentinel controller is not provided. Use antenna cable assembly (P/N 102-2378) for this application. Step 6 – Install the provided ground lug to the antenna surge protector. Use a 6 AWG (10 mm2) solid-core, bare copper ground wire to connect the ground lug to an earth ground. A copper-clad ground rod is best suited for the earth ground application. See Figure 4. Avoid wire bends of less than 12 ” (30.5cm) radius. Important: The ground path must be as direct as possible, without sharp bends, and should have 10 ohms or less resistance (when measured with an earth ground resistance testing device). Step 7 – Slide the vinyl boot over the antenna lead connection. Weatherproof the surge protector and cable connections using the provided weatherproofing kit. Refer to the installation instructions included with the weatherproofing kit for proper installation. Step 8 – Secure the surge protector to the metal antenna base with wires or cable ties (not provided). Provide a drip loop in the antenna cable as shown in Figure 4. Step 9 – Connect the antenna cable to the Sentinel controller and test for proper operation.
