Functional Advantages

Cost-Saving HD Reception

Supports free access to local HD channels (news, sports, entertainment) without monthly fees, compatible with 1080p/4K TVs.

Indoor-Optimized Signal Capture

 Engineered to pick up digital signals in enclosed spaces, with anti-interference design to reduce signal loss.

 LOW VSWR AND STABLE IMPEDANCE

It has a VSWR of less than 1.5 and a normal impedance of 50Ω. The low VSWR indicates excellent impedance matching, reducing signal reflection and ensuring efficient power transfer. The stable 50Ω impedance further contributes to the antenna's reliable performance, resulting in a more stable and consistent wireless connection.
