  What is the advantage of Satellite TV for my boat?
Many people I speak to say,  "We don't watch TV on our boat, we enjoy not having it !!!!".  My reply is "Well, you don't watch TV on your boat, as you can't ".  They then tend to agree it would be nice to watch the news, the weather or sport sometimes.

Two types of television are available for boats standard Terrestrial and Satellite.  

Terrestrial is designed for land based television, where an antenna is not moving and is aligned with the broadcast transmitter.  Boats are always moving so an Antenna cannot be perfectly aligned to the transmitter, and also boats are at sea level surrounded by hilly areas and cliffs.  Have a look at houses on the water, many have antennas up to 20 to 30m above their roof to get a signal. This can only be done on a yacht by placing the antenna at the top of the mast, but this is still not successful, as when the yachts rocks or moves the antenna swings many metres at a time. Terrestrial Television is not designed or suitable for boats.

Satellite is transmitted thousands of kilometres to earth from a gyro stationary Satellite located close to the equator.   Australia's TV Satellites are located above New Guinea, 33,000km in the sky.  Ocean TV Marine Satellite Antennas are designed to be used on boats to track these TV Satellites and will the aid of gyro stabilisation, will lock onto the Satellite whether the boat is rocking, turning, swinging on a mooring, or travelling at speed.  As long as the antenna is not blocked by cliff or mountain, which is very rare, a perfect digital TV picture will be received.

Therefore the advantage of satellite television is the choice of either Pay or FTA TV, high quality HD Digital Signal no matter where you are located on the water within the Satellites shadow.  For example in Sydney, Terrestrial TV reception is poor in Sydney Harbour and non existent in Broken Bay, Pittwater and Hawkesbury River, a Ocean TV Antenna will give you access to hundreds of Pay TV Stations, or perfect Digital FTA TV.

Many customers find they use their boat more often when they have access to quality Television, with the ability to watch News, Movies and Sport were and when they want to.

  What Size Antenna do I need?
Size of Antenna depends on three things:

1. Where your vessel is located.
2. Where you intend to spend your time cruising.
3. Whether you wish to watch Pay/Subscription TV,  Free to Air TV, or both.

Below is a map of areas that can be expected for Pay TV for OCEAN TV Antennas.

Dish Size Required
Ocean O32   Yellow - 2 Axis Stabilisation
Ocean O37M Yellow - 2 Axis Stabilisation
Ocean O45M Red    -  3 Axis Stabilisation
Ocean O60M Purple - 3 Axis Stabilisation
Ocean O700M Green -  4 Axis Stabilisation
Ocean O900M Blue    -  4 Axis Stabilisation

The Map at left gives a general idea of the areas each size Ocean TV Antenna will operate with a Pay/Subscription Satellite Receiver on Optus D3 Satellite.  
Free to Air Television on the Optus Satellite C3 has a smaller coverage area.  Please contact Ocean TV for FTA coverage areas.
These areas are for reference only and not guaranteed, satellite TV is subject to a number of conditions out of our control, including climatic weather conditions.

  I just want Free to Air TV, I live in Sydney and travel to the Gold Coast once a year, what do I need?
Minimum size we would recommend  is the Ocean TV O37M, and you will require a FTA Satellite Receiver Box.
  Will weather conditions effect Satellite TV?
Yes, all Satellite TV will be effected by poor weather conditions, mainly by very heavy cloud and heavy rain (Rain Fade).  The Optus C1 and D3 Satellites are located over 33,000km up in the sky over New Guinea, and even Satellite Dishes installed on houses, (65cm and 85cm) will lose reception in heavy rain. 

Of course it depends on the size of the Satellite TV Antenna (the bigger the antenna the less drop out during rain), and also whether you are watching Pay TV or Free to Air TV.  FTA will drop out sooner then Pay TV as it uses the older and less powerful Optus C1 Satellite.  Pay TV will rarely drop out.

But in saying this, the actual Satellite TV antenna will keep tracking all the time, it is more a function of the type of Satellite Receiver used (Pay or FTA) and which satellite is being used at the time.

  I do most of the work on my boat, can I install a Ocean TV Antenna myself?
Yes of course.  Ocean TV Antennas have been designed to "Plug n Play".  There is no need to connect a laptop computer, or work your way through complicated menus to set up the system.  It is this simple:

1. Connect the supplied Antenna Cable from the Ocean TV Antenna to the Control Box.
2. Connect the control box to 12/24vdc or use a AC 12/24vdc Adapter
3. Connect the control box to a Satellite Receiver box with the supplied Cable.
4. Connect the Satellite Receiver Box to a Television.
5. Switch on the Control Box and Satellite Receiver Box, and within 20 seconds the antenna will be tracking the correct satellite for Australia.
6. The Satellite Receiver Box will now scam for channels and install them automatically for the area you are registered in.

Of course the hardest part of the install is normally the running of the cables, suppliers like Ocean TV can supply names of professional approved Installers if required, who will have the experience with running cables and installing Ocean TV Antennas.

  Can I watch a different channel on each TV in my Boat?
Yes of course, but you will need a separate Satellite Receiver Box for each television you have on board.  On Ocean TV the Satellite Receiver Box can be either FTA or Pay TV.  Many customers will install a Pay TV Receiver in the main Cabin, and then FTA Receivers on the other TV's. 

There are many choices a customer has when installing the Satellite TV System, some are below

1. One Satellite TV Receiver (Pay or FTA) repeated to all TV's in the boat, but only one channel can be watched at a time.
2. Separate Satellite Receivers (Pay or FTA) for each TV, different channels can be watched on each TV.
3. Pay TV Receiver in Main Cabin repeated to each TV in Boat, then a FTA Receiver for each TV.  Allows Pay TV to be viewed on each TV, only one channel at a time, but each TV also has access to FTA Channels which can be different at each TV.

  How high do I need to install my Satellite TV Antenna?
Height is not a problem with Satellite TV, many antennas have been installed on a lower deck area.  The Ocean TV Antenna needs to be placed in clear view of the sky, any obstructions may block the antenna when the boat moves.  We suggest if you have any doubt, first try the antenna in the desired location before actually installing it.  Sometimes moving the antenna a few centimetres  can make a big difference, and the obstruction will be cleared

If you have any doubts about where to fit the antenna see our links pages for businesses that can help, For example, hundreds of Ocean TV Antennas have been installed, and chances are a successful installation has already been done on boat the same or very similar to yours.  Ocean TV will advise the ideal location an antenna on your vessel, and possibly have a photo of an antenna installed on a similar boat.

  Does the Ocean TV Antenna use much power?
The Ocean TV O32 and O37M actual antennas use less than 2 amps of power on 12vdc, the larger models use less than 3amps.  We have many successful installs on yachts, catamarans, houseboats and small power boats that do not have a genset.  Combined with the modern 12v LED Televisions, it is possible to have perfect Satellite Television if of course the power is managed.
  What does Auto-Skew of the LNB mean?  
All Ocean TV Antennas from the O45M and larger, feature an inbuilt 24 channel GPS and Auto-Skew LNB. 

The LNB (Low Noise Block) is the device on the front of a satellite dish that receives the very low level microwave signal from the satellite, amplifies it, changes the signals to a lower frequency band and sends them down the cable to the indoor receiver.  As antenna on the vessel moves further east or west, the angle from which it receives the signal from the satellite gets skewed.  The inbuilt GPS plots the location of the antenna, and send the information to the Ocean TV Satellite Database.  From this database the Antenna automatically calculates how much it needs to turn the LNB to allow for the changing angle to the Satellite.  This allows the antenna to be finely tuned continually while the vessel is moving.

  Can I use my boats existing cabling for Ocean TV?  
Some cabling can be used, but generally we recommend replacing all cabling.   As Ocean TV Antennas can have both HD TV and SD Digital TV Satellite Receivers connected, we recommend the use of HDMI Cables for connection of the Satellite TV Receivers to Televisions, to give optimum results. 

The old Antenna cable that is already in the boat running from your existing Terrestrial Antenna should also be replaced Ocean TV Antennas use the newer RG6 Coaxial Cable that is Quad Shielded, and also has more copper in the cable.  The shielding will be more resistant to other devices in teh boat , and the extra copper will have less voltage drop.

Sometimes the existing AV Cables can be used if the TV is an older non HDMI equipped TV, or can be used to connect the Satellite Receiver to the on board Stereo System.

  Will an Ocean TV Antenna receive Internet or Satellite Phone? 
No, Ocean TV Antennas are designed for the KU Satellite Band, which is for Satellite TV.  Satellite Internet and Satellite Phones, use a different type of Satellite Antenna.
