TV Antenna masthead amplifiers
In order to improve TV reception in an area with poor signal or in a house with many outlets, a masthead amplifier can be used which functions as both a distribution and amplifier. It is recommended to install the masthead amplifier as close to the antenna as possible, preferably on the mast itself. In larger houses or multi-unit buildings, distribution amplifiers can also be installed inside the house.
To determine whether an antenna amplifier or distribution amplifier is needed, signal strengths for all channel frequencies should be measured on-site using a DTV signal tester with a frequency scanner and CBER/VBER values. This data will help determine which type of amplifier is required.
It's important to note that masthead amplifiers are not the same as antenna boosters, which are often sold in electronics stores. These simple distribution amplifiers, marketed as "antenna boosters," will only amplify noise if a satisfactory signal is not received from the antenna. Boosting a non-existent signal is impossible, much like boosting intelligence that doesn't exist :).

Masthead versus distribution amplifiers
Masthead booster amplifies the weak signal from the antenna and compensate for the loss of signal in the splitter and cables. Distribution amp compensates signal loss on splitting to outlets in units and townhouses. Whether you need amps and what type depends on the specific installation.
Antenna power supplies
A TV antenna amplifier needs a power adapter, one and the only one in the house. If the power supply for the antenna is faulty or switched off you won't have reception from all antenna outlets in the house. There are few types of power supply for different antenna amps. The wrong adapter type may not work right or burn out the antenna amp.
