Buying Guide

Choose the right cable type

RG6 is the common standard for TV antenna runs; it balances bandwidth and attenuation for typical over-the-air reception

Check shielding and impedance

Dual or quad shielding reduces interference and keeps impedance at 75 ohms, which is essential for consistent antenna performance

Prioritize outdoor/weatherproof features

For exterior runs select UV-resistant jackets and weatherproof ratings to prevent degradation from sunlight and moisture

Match connectors to your setup

Compression brass connectors provide a secure, low-loss connection—confirm compatibility with RG6 and the connector style on your antenna and tuner

Consider cable length and signal loss

Longer runs increase attenuation; plan shorter lengths where possible or use higher-quality RG6 to reduce signal loss over distance
