4. Postavljanje i instalacija
Follow these steps for proper installation of your Triax MFA 657 LTE 700 Masthead Ampdizalica:
- Montaža: Sigurno montirajte amplifier to a mast or suitable outdoor structure using appropriate mounting hardware (not included). Ensure it is positioned to minimize cable length from the antennas.
- Antenski priključci:
- Connect your UHF antenna cable to the input port labeled UHF.
- Connect your BIII/DAB/RNT antenna cable to the input port labeled BIII/DAB/RNT.
- Connect your FM antenna cable to the input port labeled FM.
- Ensure all F-connectors are tightened securely to prevent signal loss and moisture ingress.
- Izlazna veza: Spojite izlazni kabel iz amplifier to your indoor distribution system or directly to your television/receiver. This cable will also carry the 24 VDC power to the amplifier.
- Priključak za napajanje: Connect the 24 VDC power supply (not included, typically a power inserter) to the indoor end of the output cable. Ensure the power supply is compatible with the amplifier's requirements (24V/42mA).
- Uključeno: Once all connections are secure, plug in the power supply. The amplifier will now be active.
5. Operacija
The Triax MFA 657 LTE 700 operates automatically once powered. The primary operational aspect is adjusting the gain for each input to achieve optimal signal levels without overdriving your receiver.
Podešavanje pojačanja:
The amplifier features adjustable gain controls for each input (UHF, BIII/DAB/RNT, FM). These controls are typically small potentiometers located on the amplifier unit, as shown in Figure 3.1. Use a small screwdriver to carefully adjust the gain for each band:
- UHF Gain: Adjustable from 20dB to 35dB. Adjust this to optimize digital terrestrial television (DTT) signals.
- BIII/DAB/RNT Gain: Adjustable from 10dB to 22dB. Use this for DAB radio and other BIII band signals.
- FM Gain: Adjustable from 10dB to 22dB. Adjust for optimal FM radio reception.
Preporuka: Start with the lowest gain setting and gradually increase it until you achieve a clear, stable picture and sound on your television or radio. Avoid setting the gain too high, as this can lead to signal distortion and pixelation (overdriving).
6. Održavanje
The Triax MFA 657 LTE 700 Masthead Amplifier is designed for minimal maintenance. However, periodic checks can ensure its longevity and optimal performance:
- Kablovske veze: Periodically inspect all F-connectors for corrosion or looseness. Ensure they are clean and tightly secured.
- Zaštita od vremenskih prilika: While designed for outdoor use, ensure the housing is intact and free from cracks or damage that could allow water ingress.
- čišćenje: If necessary, gently wipe the exterior of the unit with a soft, damp tkanina. Nemojte koristiti jake hemikalije ili abrazivna sredstva za čišćenje.
- Faktori okoline: Ensure no debris (e.g., leaves, bird nests) is obstructing the unit or its ventilation.
