With a diplexer, it’s possible to quickly and easily combine a satellite TV signal with a terrestrial TV (off-air) signal or FM radio signal and then distribute them on one output.

This allows one cable to transport multiple signals around the house / place of business.  The combined signals can then be split when they reach the receiver box or TV.

Combining a local terrestrial or cable TV signal with a [easyazon-link keywords=”diplexer” locale=”us”]diplexer[/easyazon-link] overcomes this problem.

A diplexer, also commonly known as a signal splitter, can be a great way to ensure that everyone in a home or building has access to their own satellite TV stream by splitting one satellite TV signal into two or more outputs.

If you are running a business a diplexer combined with a multiswitch to save you a fortune in supplying multiple TV sets from one satellite dish, and minimising the amount of cable runs required.

Without a diplexer, it may not be possible to use a satellite dish to distribute more than one signal. For example, many sports bars and family restaurants have lots of televisions tuned to different channels.

In addition, a diplexer can be a valuable tool for homes. With the advent of new communication and entertainment technologies, many modern homes have two or more televisions.

While it’s nice to have multiple televisions, they are of limited use if they can only be used to view the same television station. With TV splitters, everyone can enjoy their favorite television show without the need for multiple satellite dishes. With a diplexer, it’s possible to view multiple channels through the same satellite dish.
