1. Proizvod je gotovview
The Televes Mast Amplifier is an advanced device designed to optimize TV frequencies, ensuring maximum reception and signal quality. Featuring TForce technology and two inputs covering the entire TV band, it allows for combining two TV antennas. Its automatic gain control independently adjusts signal levels per band (UHF, high VHF, low VHF), preventing over or under amplification. Constructed from durable cast metal and high-grade ABS plastic, it is built to withstand harsh outdoor conditions. The included UL-listed power supply offers two outputs for convenient signal distribution.
2. Ključne karakteristike
- Dvopojasni amplification with independent automatic gain regulation per band.
- Low noise and high output level (47 dBmV UHF, 43 dBmV VHF).
- Maximum gain: 27 dB (UHF, channels 14-36), 18 dB (high VHF, channels 7-13), 18 dB (low VHF, channels 2-6).
- “F” connectors for secure connections.
- On/off switch to allow DC passing towards the input to power up BOSS system.
- Robust construction from cast metal and high-grade ABS plastic for outdoor durability.
- High screening cast metal chassis for best-in-class electromagnetic shielding.
- UL-listed power supply with two outputs included.
3. Postavljanje i instalacija
Proper installation is crucial for optimal performance. Follow these steps for setting up your Televes Mast Ampdizalica:
-
Montaža Ampdizalica: Sigurno montirajte amplifier in a suitable outdoor location, preferably on a mast near your antennas. Ensure it is protected from direct heavy rain and extreme weather conditions. The robust casing is designed for outdoor use, but proper mounting helps longevity.

-
Povezivanje antena: Connect your TV antennas to the "IN VHF/UHF" ports using F-type coaxial cables. This amplifier supports two antennas, allowing you to combine signals from different directions or types (e.g., one for VHF, one for UHF).

- Priključivanje na napajanje: Connect the "RF OUT DC IN" port of the amplifier to the power supply unit using a coaxial cable. The power supply unit is designed to inject power into the coaxial line to power the mast amplifier.
- Connecting to TV/Distribution: The power supply unit has two outputs. Connect one or both outputs to your TV sets or a distribution system (e.g., a splitter or another ampživotni vijek) pomoću koaksijalnih kablova.
- BOSS System Power: If you are using an active antenna with a built-in BOSS system, ensure the "ON/OFF" switch on the amplifier is set to "ON" to allow DC power to pass through to the antenna. If your antenna does not require power, set the switch to "OFF".
- Uključivanje: Plug the power supply unit into a standard electrical outlet. The "Power LED" on the amplifier should illuminate, indicating it is receiving power.

4. Principi rada
The Televes Mast Amplifier utilizes advanced TForce technology and automatic gain control (AGC) to ensure optimal signal levels. Unlike fixed-gain preamplifiers, this unit intelligently adjusts amplification based on incoming signal strength, preventing signal overload or under-amplification. This independent gain control per band (VHF and UHF) means that adjustments to one frequency range do not negatively impact others, providing a stable and clear signal across all channels.
The precise band filtering effectively blocks out interference from unwanted signals, such as FM radio and nearby 5G cellular towers. This is crucial for maintaining signal integrity, especially in areas with strong interfering signals. By only amplifying the relevant TV bands (low VHF, high VHF, and UHF), the amplifier minimizes noise and maximizes the quality of your received television channels.
5. Održavanje
The Televes Mast Amplifier is designed for durability and minimal maintenance. However, periodic checks can help ensure its long-term performance:
- Integritet veze: Periodically inspect all F-type coaxial cable connections to ensure they are tight and free from corrosion. Loose or corroded connections can degrade signal quality.
- Casing Inspekcija: While the unit is constructed from robust materials, inspect the outer casing for any signs of physical damage, cracks, or openings that could compromise its weather resistance. Ensure the protective cover is securely closed.
- Stanje kabla: Check the coaxial cables for any fraying, cuts, or damage, especially where they enter or exit the ampdizalo i napajanje.
- Jedinica za napajanje: Ensure the power supply unit is kept in a dry, indoor environment and is not subjected to extreme temperatures.
