More features

• Enjoy Local HD Broadcast Channels — No Monthly Subscription Where Available. Get local over‑the‑air news, sports, and primetime shows on compatible HDTVs with no recurring fees. Channel availability depends on local broadcast coverage, tower distance, terrain, and building obstructions. You may reference DTV.gov to review local signal conditions prior to purchase. Not a streaming service; it does not deliver cable‑only or streaming channels
• Dual‑Amplified Signal Booster with Smart Chip — USB Power Required for Amplified Mode. Dual‑amplifier and smart chip boost weak broadcast signals and reduce partial cell‑tower/RF interference. Mounting brackets included for attic or rooftop installation. Turn off amplifier if local signals are strong to avoid overload. Optimal performance requires existing local broadcast signals
• Rental‑Friendly No‑Drill Mounting — Test Surface First. Works great for apartments, rentals, dorms and condos. Use the included heavy‑duty double‑sided tape only on clean, smooth flat surfaces like windows and walls; poor adhesion on rough, dusty or freshly‑painted surfaces. Locate near a window for better reception and re‑scan channels after repositioning antenna
• Weather‑Resistant Indoor/Outdoor Use — 33ft Coax Cable. Rugged flame‑retardant, water‑resistant housing supports window, balcony, attic or rooftop installation. Heavy storms may temporarily impact signal quality. 33‑foot cable helps you locate the optimal signal spot
• Tool‑Free 2‑Step Setup for TVs with Built‑In Tuners. Step 1: Plug coax cable into your TV’s “ANT IN” / “CABLE IN” port. Step 2: Go to TV Settings > Channels, select Antenna/Air and run full channel scan. Compatible with HDTVs featuring built‑in ATSC tuners. Older analog TVs or tuner‑less smart TVs need an external digital set‑top box. Always re‑scan after repositioning antenna
