Antena de TV exterior Maximum 20643

The Maximum 20643 outdoor television antenna is designed to receive DVB-T/T2 signals within the 470–790 MHz frequency range. Its compact form factor and lightweight construction make it suitable for mounting on a roof, mast or balcony. The antenna is finished in black and silver and supports operation from standard household AC supply and a 12 V DC source, allowing flexible installation options for residential or secondary-site use.

Advantages

The antenna provides reliable reception across the UHF band (470–790 MHz), delivering stable digital television signals in areas with adequate coverage. Its lightweight design at approximately 1.4 kg simplifies handling and installation, while the compact depth dimension (740 mm) reduces wind load and visual impact. Dual-power compatibility with 110–230 V AC and 12 V DC input enables use with typical home power or vehicle/portable power systems. The black and silver finish offers a neutral appearance that integrates with most exterior installations.

How to use

Mount the antenna securely on a mast or suitable bracket at a height that provides a clear line of sight toward broadcast transmitters. Connect the antenna coaxial cable to the TV or set-top box input and, if required, supply power using either the AC or 12 V DC input according to your setup. After connection, perform a channel scan on the television or tuner to detect available channels. If reception is weak, fine-tune the antenna orientation in small increments until signal strength and quality improve.

Recommendations

For best results, install the antenna as high as practical and away from large metal obstructions. Use a quality, weather-rated coaxial cable and properly sealed outdoor connectors to minimize signal loss and prevent water ingress. If installing in an area with marginal reception, consider using a low-noise amplifier designed for the UHF band, placed close to the antenna.
