ANTENNA AMPLIFIER

Antenna amplifier

With a quality antenna amplifier, you can often avoid problems with poor signal due to weak or unevenly amplified TV antenna signal, usually experienced when you connect multiple TVs to an antenna or a cable TV installation.

Amplifiers for cable TV (DVB-C) antenne installations

Antenna amplifiers for cable TV are usually characterised by being useable for a wider frequency range than amplifiers for normal antenna, as 4G/LTE frequencies (800 MHz band) do not need to be taken into account in the antenna signal. For the most future-proof installation, we therefore recommend that you choose an amplifier which can amplify up to the 1000 MHz range, as the Triax IFA 384 and 388 models can.

Furthermore, it is a good idea to choose a model with tilt/slope adjustment. This can compensate for a poor signal at one end of the frequency range, which is often the result of long cable routes, e.g. if you live at the end of a residential street or in the outer flat of a block of flats.

For an antenna amplifier for cable TV, it is often possible to loop the return path for Internet via cable TV, although only passive return paths are generally used in Denmark.

Avoid amplified mobile noise (LTE /4G / 5G) in antenna installations

An antenna amplifier for a regular house antenna is often a normal, simple line amplifier without a return path option and tilt/slope adjustment is often not necessary. However, it is no problem that they have it, but you can still choose to save a bit.
It is very important that the antenna installation is 4G/LTE protected, among others, from the antenna and down to the amplifier, preferably using a 4G-LTE stopfilter.

Remember that it is still important to terminere unused and open antenna outputs in the amplifier, as otherwise 4G/LTE noice risks entering the antenna system.
