Profitĭecibels (dB) measure the level of gain generated by amplifiers.

You can have a successful and better TV reception with either of the two types. These can block the voltage that is being sent up the cable to power the amp, which results in a reduced signal.
#AMPLIFICATEUR ANTENNE TV 12V INSTALL#
Make sure to not install any devices between your preamplifier and the power supply. Place the indoor amplifier close to the television. Install the amplifier as close to the antenna as possible. We recommend the following shopping criteria to make a great purchase.Īs mentioned above, there are two main types when it comes to amplifiers: mast and indoor. That’s why we have created this guide in the first place: to help users find their best match. Nevertheless, do a little bit of research and read our advice. Of course, finding the best TV antenna amplifier may not be an easy task, since there is a vast number of similar devices with similar specifications but completely different performances of which you may not be aware. Shopping Criteria for TV Antenna Amplifiers These are less expensive than mast amplifiers. They are therefore considered after the installation of another type of amplifier. They are normally used at the same time as other amplifiers. Usually used to boost a weak signal for a specific device. Generates a 16 dB to 24 dB increase in signal. The amplifier is installed close to the signal source to avoid receiving a weak signal. There are models that have up to a dozen output sockets. The signal strength increase is between 30 and 40 decibels (dB). Needs to transform the power supply from 220 volts to 12 or 24 volts. Here are some of the characteristics of each type of amplifier: Mast amplifier A distribution amplifier is usually mounted indoors and is used when supplying a signal to multiple TVs. The advantage to this is the signal is amplified at its strongest point when it comes off at the antenna. A preamplifier is mounted to the mast and amplifies the signal coming directly from the antenna. It is important to know the difference between a preamplifier and a distribution amplifier.
