Installation and Debugging Manual for Satellite TV Antenna
There are 5 main steps to install and debug the satellite TV antenna as below. After studying this manual, you’ll be able to install and debug the satellite TV antenna by DIY.
1. Prepare required tools and materials
Tools:
Hammer, Compass, Marker, Drill and appropriate bit, Adjustable spanner, Helping tool for metallic wall plugs fixing.
Materials
Dish with All Pieces, L-Wall Mount, Stainless Steel Washers, F Connectors, Metallic Wall Plugs, Coaxial Cable for Satellite Signal, Hexagonal Screws, Digital TV Receiver or PCI Card or USB Receiver.
About antenna diameter choosing
According to the geographical location to install antenna
According to the signal field intensity of satellite used
2. Install antenna mount
Steps:
Firstly, find a suitable position based on the following two requirements:
①Measure and calculate the antenna AZ and El angle by a compass so that the antenna can align the satellite correctly at this installation position.
②There mustn’t be any barriers around the place of antenna aligning satellite.Put the “L” type antenna mount to the installed position by hand, and mark 4 signs with a marking pen according to the installation holes.
Drill 4 holes with an electric drill according to the marked holes. Usually the hole depth is best within 0~5cm.
Insert the expansion bolt to the 4 holes, and knock on the expansion bolt with a hammer so that the expansion bolt can be inserted into the 4 holes completely.
Install L type antenna mount, fasten the flat gasket, spring washer and nuts at the corresponding holes.
3. Install antenna reflector
Steps
For different model and brand product, the installation method also varies. The following picture is the installation diagram of Antesky antenna reflector.
Reflector installation consists of LNB, fastening bolts, and the position sign to align the satellite correctly marked in red as shown in below picture.
4. Debug the antenna to align satellite
How to make antenna align the satellite accurately?
Generally, we can find the satellite parameters to receive on the Lyngsat website and calculate the antenna AZ&El&Pol angle etc. according to the antenna installation location. Meanwhile according to the antenna installation location, we can also calculate the antenna AZ&El&Pol parameter by Dishpointer software, and then debug antenna to align the satellite according to these parameters. As shown in the below picture:
AZ angle:
AZ angle refers to the horizontal angle from the north line of a certain point to the target direction line by CW moving.
El angle
El angle refers to pitching angle of antenna relative to the XOY plane of inertial coordinate system.
Pol. angle
Pol. angle refers to the angle when antenna and satellite radiation electromagnetic wave satisfy polarization matching. Suppose the satellite beam center is at the same longitude with satellite, the receiving antenna at the same longitude with subpoint will match well with the satellite radiation electromagnetic wave, while the polarization of non-subpoint receiving antenna at different longitude with subpoint can’t match with the satellite electromagnetic wave until rotating a certain angle.
All the parameters depend on the following two factors:
①The geographical location to install antenna;
②The longitude of adopted satellite.
5. Connect the cables and receive TV signals
Make co-axial cables
Connect the cables, debug and receive satellite signals
