Place the antenna booster as close to the antenna as possible to minimize signal loss, ideally within one meter, as signal attenuation occurs at about 3dB per meter of coaxial cable.
Near the antenna
For the antenna amplifier to work best, it should be placed as close to the antenna as possible. The signal in standard coaxial cable will be attenuated by about 3dB per meter, and the further the antenna amplifier is from the antenna, the more obvious this loss is.
“To make the antenna amplifier as close as possible to the antenna, so that the signal loss can be minimized,” this sentence has been repeatedly mentioned in many professional technical forums, the United States FCC experts have also emphasized this point, a well-known electronic products company has found in their product testing that the distance between the amplifier and the antenna is reduced by one meter, the signal quality is improved by about 10%.
Altitude
That the efficiency of signal reception can be increased by 5% for every meter of amplifier elevation from the ground. According to industry statistics, the signal reception efficiency at altitude is about 20% higher than on the ground. A study by a well-known communications company, tested the signal at different altitudes and showed that the signal quality of the amplifier at 10 meters above the ground improved by about 25% compared to the ground.
Mr. Zhang lives in a 30-story building, and the TV signal in his home has been unstable. He tried to install the antenna amplifier on the balcony but it didn’t work well. When he moved the amplifier to the roof, the signal quality improved dramatically and the images became very clear.
That electromagnetic interference is most severe in areas below 5 meters above the ground, while it is significantly reduced at altitudes above 10 meters. The best operating temperature of most antenna amplifiers is between -10 °C and 50 °C, and being placed at a high altitude, especially in a well-ventilated position, can effectively reduce the operating temperature of the equipment and extend its service life.
Long-term exposure to bad weather conditions will affect its life, according to product specifications most antenna amplifier design life of 5-10 years, if you can take appropriate protective measures such as installing a waterproof cover, regular inspection and maintenance, its actual service life can be extended by about 30%.
Avoid interference sources
Microwave ovens, wireless routers, and other electronic devices all produce electromagnetic waves that can interfere with antenna signals. The data shows that when the microwave oven is working, the strength of the nearby wireless signal will drop by about 30%.
Close to power source
According to industry standards, the operating voltage of most antenna amplifiers is between 5V and 12V, and the current requirement is around 500mA to 1A. About 20% of antenna amplifier failures are caused by power supply problems, and placing close to the power outlet can facilitate quick troubleshooting and solving the problem, the signal attenuation is about 0.2dB for every 1 meter extension of the cable.
