Κεραία εξωτερικού χώρου Televes 149921 Dual 17 dB

The Televes 149921 Dual outdoor antenna delivers 17 dB gain and is engineered for stable UHF (DTT) reception with built-in BOSSTech and TForce MMIC technologies. It optimizes LTE band rejection up to channel 48 (694 MHz) and is powered by a 12–24 V DC supply. Constructed from aluminium and ABS, with a compact footprint (1142 × 560 × 736 mm) and weighing 2.086 kg, this orange outdoor antenna is suited for standard external TV installations where extended dynamic range and reliable reception are required.

Advantages

The integrated BOSSTech system provides smart signal management that balances weak and strong signals to maintain optimal reception levels. TForce MMIC technology, manufactured using gallium arsenide (GaAs) semiconductor compounds, improves microwave-frequency performance and enhances dynamic range. The antenna design includes LTE rejection up to channel 48, reducing interference from mobile networks. Durable aluminium and ABS construction and a 12–24 V DC power range make the unit practical for a variety of outdoor installations.

Suitable for

• Outdoor digital terrestrial TV (DTT/UHF) reception
• Areas with mixed weak and strong broadcast signals
• Installations requiring LTE interference rejection up to 694 MHz (ch.48)
• Single or dual-antenna mounting for residential or small commercial sites

How to use

Mount the Televes 149921 outdoor antenna on a suitable pole or bracket following local mounting standards, ensuring the antenna is securely fixed and oriented toward the broadcast transmitters for best UHF reception. Connect the antenna to a receiver or distribution amplifier using appropriate coaxial cable and provide the required 12–24 V DC power to activate the BOSSTech and TForce electronics. After installation, perform a channel scan on the receiver and fine-tune the antenna orientation to achieve maximum signal quality.

Recommendations

For reliable long-term performance, use weatherproof connectors and high-quality coaxial cable; place the antenna at a clear, elevated location away from large metal obstructions. If LTE/mobile interference persists, verify cabling and grounding and consider additional filtering or professional alignment.
