What is Free to Air Satellite Television
There are many international channels which can be received for free with a satellite dish and receiver. All channels are broadcasted in digital format, which means you get crystal clear pictures and CD quality sound on every channel. There are many foreign language channels available free to air on a number of satellites visible to us in New Zealand. There are many channels from Asian countries, including Thailand, China, Taiwan, Japan, and India. From Europe there are channels from Germany, France, Italy, Holland, Croatia, Greece, Turkey, England, and Portugal. To receive free to air satellite TV and radio channels available from countries all over the world you need a dish and digital satellite receiver.
How many TV programs can your Satellite Receiver receive?
In theory, our Satellite Receiver can receive all free to air satellite TV programs from all around the world if the dish can retrieve the TV signal from the satellite. In reality, only some satellites cover New Zealand, which means you can only receive the TV programs from those satellites.
Can I use this box to receive PAY TV program?
Some model of Dreamax and Strong Satellite Receivers on our web site have smart card slot , and are able to receive pay TV if you subscribe to the service.  NOTE: SKY TV uses its own system, so none of the receivers on the market can read Sky Card, except the Sky Box. 
Do I need a professional installer to install your receiver?
It is not a straight forward installation. Since the installation is related to the dish and LNB. We highly recommend you to consult a professional installer if you do NOT have the knowledge to do it.
Installation tips for people who have an existing Sky dish and LNB:
First of all, make sure your LNB and dish are connected well.  You may need to check the dish set up, make sure it points to the correct direction in the right angle. Check the LNB frequency printed on the body of the LNB, use the information when setting up your receiver.  Check if the cable is connected properly. The box will work only if the satellite dish and LNB have been set up properly, otherwise it is just waste of time trying to set up the receiver. Test the satellite signal strength with a satellite finder, you may connect the cable to a working satellite receiver if you have one, to make sure there is good signal on the cable. Another way to test the new receiver is to take it to your friend’s place where there is a working dish and LNB. The Optus D1, which the FREEVIEW TV programs broadcasted from, has been pre-set on our satellite receiver. Press "Menu" button on the remote control to get to menu screen, installation, automatic channel search, choose Optus D1 from the satellite list by using left/ right and up/down arrow key on the R/C, then go to option in the bottom and use left and right arrow key on the R/C to start the search (Choose either All or FTA from the pop up menu). All FREEVIEW TV programs should appear on the screen. Select save from option to save all the TV program settings. You can also use manual installation if you have the related knowledge. But you don't actually need to use it to set it up. Please check our website for Step by Step Instruction Guide, which is based on SKY dish and 11300 frequency LNB. Another very helpful website is www.lyngsat.com. We also highly recommend you to consult a professional installer or who has the knowledge to help you out. Alternatively, you can look at the internet and there is plenty of info available. In case you can't set it up properly and would like to go back to the original status, you can go to installation, and choose factory default to reset the box to factory default. It is very helpful tool to use. But you need to go back to installation menu, automatic channel search and choose Optus D1 satellite. Check and make sure the LNB low frequency is set to match as yours, in most cases, it should be set as 11300 after you use this reset function.  
I don’t have a Sky dish. What else do I need to install a Satellite system apart from the Receiver?
A Satellite Dish is a type of parabolic antenna designed with the specific purpose of transmitting signals to and/or receiving from satellites. A satellite dish is a particular type of microwave antenna. Satellite dishes come in varying sizes and designs, and are most commonly used to receive satellite television. The parabolic shape of a dish reflects the signal to the dish’s focal point. Mounted on brackets at the dish's focal point is a device called a feedhorn. This feedhorn is essentially the front-end of a waveguide that gathers the signals at or near the focal point and 'conducts' them to a LNB. The LNB converts the signals from electromagnetic or radio waves to electrical signals and shifts the signals from the down linked C-band and/or Ku-band to the L-band range. To view the FREEVIEW TV programs, your dish size should not smaller than 65cm. The bigger the dish, the better the result. You may need the big dish, up to 2.4M if you like to receive other or more satellite TV program signal. 2. LNB
Low-Noise Block converter is used in communications satellite (usually broadcast satellite) reception (downlink). The LNB is usually fixed on or in the satellite dish, for the reasons outlined below. Satellites use comparatively high radio frequencies to transmit their signals. As microwave satellite signals do not easily pass through walls, roofs, or even glass windows, satellite antennas are required to be outdoor, and the signal needs to be passed indoors via cables. When radio signals are sent through coaxial cables, the higher the frequency, the more losses occur in the cable per unit of length. The job of the LNB is to take a wide block (or band) of relatively high frequencies, amplify and convert them to similar signals carried at a much lower frequency. These lower frequencies travel through cables with much less attenuation of the signal, so there is much more signal left on the satellite receiver end of the cable. A Normal or Standard LNB has a 10 GHz LO and works for one band only. Normally has a feed horn assembly built onto the LNB. This LNBs polarization switching is done by a DC voltage on the coax supplied by the satellite receiver, - 12.5 to 14.5 volts gives vertical and 15.5 to 18 volts gives horizontal. A Universal LNB can receive both polarisations and the full range of frequencies in the satellite Ku or C band. Some models can receive both polarisations simultaneously through two different connectors, and others are switchable or fully adjustable in their polarisation. The Ku band is a portion of the electromagnetic spectrum in the microwave range of frequencies ranging from 12 to 18 GHz.  Ku band is primarily used for satellite communications Polarization: The orientation of the electromagnetic waves received from the satellite, which can be distinguished by the LNB (the unit that receives the beam focused by the dish). By using horizontal and vertical polarization more channels can be fitted into a frequency range. The receiver must indicate the desired polarization to the LNB by supplying it with a certain voltage (14/18 V), so it can align to it.

RG-6/U is a common type of coaxial cable used in a wide variety of residential and commercial applications. The term "RG-6" itself is quite generic and refers to a wide variety of cable designs, which differ from one another in shielding characteristics, center conductor composition, and dielectric type. RG-6 was originally a military spec where RG means Radio Guide, but is now obsolete; in practice, the term "RG-6" is generally used to refer to coaxial cables with an 18 AWG center conductor and 75 ohm characteristic impedance.

The F connector is a type of RF connector commonly used for "over the air" terrestrial television, cable television and universally for satellite television and cable modems, usually with RG-6/U cable or (in older installations) with RG-59/U cable.

5. SATELLITE FINDER (optional)
A satellite finder or meter is a device used to determine the optimum direction in which to point a satellite dish in order to receive the strongest possible signal from an orbiting satellite.

6. SMART CARD (optional)
You will need a smart card if you want to watch Pay satellite TV.  The smart card is usually provided by the service provider, and you need a satellite receiver with card slot to use the smart card.  Some model of Dreamax and Strong Satellite Receivers on our web site have smart card slot.
