USES of Terrestrial Launch Amplifier
- The launch amplifier has 2 basic functions
- It can combine the input from multiple different inputs into a single feed
- It amplifies the signal giving it a dB boost of up to 42dB so that it can be distributed to a large number of rooms
- Examples of where it might be used include...
- Combining CCTV camera output from a modulator to combine in with a TV & radio distribution system
- To give extra amplification necessary to feed signal to up to 100 TVs points through a series of taps (special TV splitters)
- For use with multiswitches (which often work well on the satellite side but sometimes can have horrible losses on the terrestrial side)
ADVANTAGES of Terrestrial Launch Amplifier
- It is a very versatile and high quality unit
- It comes at a fraction of the cost of many of its competitor products
- It has adjustable gain making it ideal for balancing out the signal over a long run
- It comes from a industry leading brand name manufacturer (Labgear)
- It allows 2 UHF signals to be combined together - a very common problem
