An antenna is only the first step in delivering a strong TV signal to your screen. Between the antenna and the television lies a cable run, possibly a splitter, and the cumulative loss of signal strength that each component introduces. An antenna signal booster — also known as a signal amplifier or line amplifier — inserts into this signal chain to compensate for these losses, ensuring that the signal arriving at each TV tuner is strong, clean, and consistently reliable. Pro-Logic Technologies in Nairobi stocks a comprehensive range of antenna signal boosters for domestic, multi-room, and commercial installations.
What Does an Antenna Signal Booster Do?
A signal booster is an active electronic device that receives an incoming RF (radio frequency) signal, amplifies it using a low-noise internal transistor circuit, and passes the amplified signal onward. The amount of amplification it provides is measured in decibels (dB) — a 10dB booster increases the signal power by a factor of ten.
Quality boosters amplify the signal with minimal added noise, preserving the signal-to-noise ratio that determines picture quality. Cheap boosters amplify noise as much as the signal, potentially worsening picture quality even as they increase signal strength.
Types of Signal Boosters
Masthead amplifiers mount at the base of the antenna mast, as close to the antenna as possible. This position maximises effectiveness because the signal is amplified before it suffers cable losses. Masthead amplifiers are powered by a DC voltage sent up the coaxial cable from a power supply unit at the TV end — a technique called “power insertion.”
Inline boosters connect at any point along the coaxial cable run, typically near the TV or at a distribution point. They are simpler to install than masthead amplifiers and are effective for compensating for long cable runs or splitter losses when the incoming signal is already reasonably strong.
Distribution amplifiers combine splitting and amplification in one unit, accepting one antenna input and providing multiple amplified outputs — ideal for feeding multiple TVs from one antenna without the signal loss that passive splitting introduces.
At Pro-Logic Technologies, we stock all three types in various gain ratings to match your specific installation requirements.
