Combining the signals from two or more sources can be done with a single cable. The equipment used for this depends on what you want to record. For example, combining the signals from two satellite dishes with one LNB can give you recording facilities over a single cable. In other cases, you will need two LNBs and two satellite dishes. When combining signals from two sources, you must make sure that both antennas are installed correctly and that the cables are connected to each other.

Dipole:

Satellite signals come in two forms: a directional, or straight, signal from the satellite and an Omni-directional, or ’tilted’ signal from an antenna. To combine these two signals to the decoder, you need a device called a diplexer. These devices combine signals from both sources and separate them into one. Depending on your receiver, you can connect both antenna and satellite signals.

 

The first type of diplexer combines the two signals. It separates satellite and terrestrial signals on separate frequencies. It is usually installed at the satellite dish or antenna on the roof. The diplexer then combines the two signals into one coaxial cable, which is connected to a wall socket. Sometimes, it is necessary to use a second diplexer to separate the two signals, which is helpful if you need to run an extra cable from the satellite dish to the decoder.

Reflector:

The size of a reflector for satellite and antenna signals is critical to their reception. The Gregorian antenna, for instance, aims to reduce sidelobes by raising the edge of the sub-reflector. Bolts are secured in the base of the sub-reflector. Moving the top bolt tilts the sub-reflector in elevation while moving the bottom two bolts only causes a diagonal or azimuth tilt. Moving a single bolt in one direction results in a tilt and focus change.

 

The feed antennas, on the other hand, are placed in a feed array and disposed of in a non-parabolic reflector. This non-parabolic reflector distributes incoming signals into multiple sub-signals, each corresponding to one of the feed antennas. Each sub-signal is then phase-shifted using a variable phase shifter. The resulting beams illuminate the non-focused reflector.

Mount:

The best way to decode satellite and terrestrial signals is to mount the antenna and satellite to the same location and align the satellite and antenna in the same direction. European linear LNBs have to be oriented in the same direction as the satellite. This way, the signals they send will be as close to the decoder as possible. The antenna can be mounted in any direction around the axis, as long as it faces the same direction as the satellite.

 

A dedicated device is used to convert the LNB signal onto an optical fibre. These units typically reside outdoors in rack shelters at the antenna site. Others are mounted directly on the satellite dish mast. A dedicated device is capable of providing redundancy on the link to the IRD, as well as setting the parameters of downlinked signals. Depending on the installation, dedicated devices can also be installed inside a satellite dish.

Mast:

Using a DISEqC switch to combine satellite and terrestrial signals to the decoder is one method. These switches combine two satellite signals with one cable, allowing recording facilities over one cable. But before you go ahead and buy the DISEqC switch, you need to learn how to combine the satellite signals. Here are some of the tips:

Diplexer:

The first step in combining satellite and antenna signals is to connect a TV antenna to the dish. Next, connect the included coaxial cable to the TV antenna’s coax output. Next, connect the coax input from the antenna to the coax input of the diplexer encoding module. Finally, disconnect the satellite receiver and diplexer decoder switch. The TV antenna should be close to the satellite dish.
