    Large dish installation guide pouring the pad if you elect to proceed with the installation of a large aperture antenna yourself, you will need to construct a foundation for the mount. In the case of a pole-mount antenna, a steel pipe is placed in a hole in the ground and embedded in concrete, becau...

    Satellites properly. Tightening beforehand can dimple the pipe, making it more difficult to make subtle adjustments in alignment. Mounting the lnb and feedhorn extreme care should be taken when bolting the lnb to the feedhorn. Do not touch the probe inside the mouth of the lnb. This probe can be adv...

    Locations on the antenna’s surface, these supports should accurately position the feed at the correct focal length: the distance between the center of the dish and the opening of the feedhorn. The correct focal length for your dish is provided in the manufacturer’s assembly manual. Once your system ...

    Receiver, and a four or five conductor wire from the actuator motor at the antenna to the control terminals on the back of the receiver or actuator power supply. We will examine each of these wires in detail in the following sections. The best way to acquire these wires is to purchase an all-in-one ...

Your local electronic supply house can provide you with the special tool used to crimp “f” connectors onto the cable, or you can purchase standard lengths of cable with the connectors already instal...

    Waterlock devices which provide an effective way to keep moisure away from the lnb’s f connector. The receiver should be unplugged from the a.C. Wall receptacle before connecting or disconnecting the coax cable from the lnb or the receiver. This eliminates the chance of a short circuit across the co...

    Wiring the actuator the direct burial cable’s actuator line is comprised of five stranded wires. Two 14 or 16 gauge stranded wires are used to power the motor and three color- coded 22 gauge shielded wires connect to the sensor. These actuator wires should be connected to the appropriate terminals o...

    You first may be instructed to “set east and west limits”. This is referring to the limits of travel for the actuator arm or horizon drive. Although the motor has a slip clutch to prevent damage when the arm is extended or retracted completely, it is best to set the receiver’s programmable limits at...

    You may have a satellite receiver that was designed to find and program the satellites on its own. However, even these “smart” receivers will require you to find and identify one upper and one lower satellite. There also are automatic dish peaking and polarity peaking features on some receivers. If ...

    If the video seems to zip off the screen as soon as you stop on the channel try changing the receiver’s polarization format. That is, if you have your odd channels set for vertical polarization and your events for horizontal, change the format to odds-horizontal, evens-vertical. You may not even kno...

If this cannot...
