Indoor HDTV Antenna 50-Mile Range

This flat indoor antenna receives VHF and UHF signals up to 50 miles from the broadcast tower. It connects via a 3.7-metre coaxial cable with an F-head and TV adapter. The amplified design delivers 20 dBi gain for clear 1080p picture quality. Adhesive backing allows simple placement on a wall or window.

Upgrade From Basic Rabbit-Ear Antennas

The amplified flat panel replaces simple dipole or loop antennas that struggle with weak or distant signals. The 20 dBi gain makes the jump worthwhile when stations are beyond the reach of passive indoor models. It supports the same 75-ohm coaxial input used by virtually all modern televisions. No external power supply is required for the amplifier section.

Limits Of Indoor Over-The-Air Reception

Building materials, terrain and multipath interference can reduce the effective range well below the 50-mile specification. The antenna covers 174–240 MHz and 470–862 MHz but cannot receive ATSC 3.0 signals outside those bands. It is not suited for outdoor mounting or for viewers who need multiple directional antennas. Cable length is fixed at 3.7 metres, so longer runs require an extension.

Questions about this item

How much wall space does the 210 mm by 120 mm flat panel need for the adhesive backing?

The antenna measures 210 mm wide by 120 mm high and only 0.8 mm thick, so the adhesive strip needs a clean, flat rectangle at least that large on a wall or window.

What is the correct order to connect the F-head, the TV adapter and the 3.7 m coaxial cable before scanning channels?

Screw the F-head onto the antenna's coaxial cable, attach the supplied TV adapter to the F-head, plug the adapter into the TV's antenna socket, then run the channel scan.

Will the 20 dBi amplified signal degrade over time, and does the amplifier need periodic replacement?

The built-in amplifier is fixed inside the antenna and rated for operation from -45 °C to 85 °C; no user-serviceable parts or scheduled replacement are specified.
