Clean horizontal dipole geometry and pure 75-Ohm impedance matching deliver rock-solid local HD without cluttering your OLED wall.
Proportioned across 330 mm to capture both 470–608 MHz UHF and 174–230 MHz Hi-VHF waves—locking in ABC, CBS, NBC, FOX, and PBS without rabbit ears.
Eliminates cheap inline USB boosters that overload city/suburban TV tuners with static—leaving your TV's USB ports free and your drywall wire-free.
Captures raw over-the-air 1080i and ATSC 3.0 4K-ready feeds with higher bitrates than compressed cable or streaming apps—plus zero game-day lag.
Rigid 118g non-glare matte-black ABS housing mounts flush on window glass, hides behind wall-mounted TVs, or tucks flat beneath your soundbar.
Mounted high on an exterior-facing window or wall, the rigid matte-black stadium wings align directly with horizontally polarized UHF and Hi-VHF broadcast waves within a 25–35 mile urban/suburban radius.
Inside the raised U-shaped central hub, a precision passive balun steps dipole energy smoothly into the triple-shielded coax with integrated 608 MHz LTE filtering—zero noisy USB power puck to clip strong local towers.
The smooth 10-foot black coaxial lead threads directly onto your TV's 75-Ohm ANT IN jack while leaving every USB port untouched—ready for a 2-minute channel scan and free HD forever.

Real-World Metro & Suburban Engineering: Cosari SignalBar skips fake '500-mile' dropshipper claims and noisy inline USB amplifiers. Tuned specifically for urban and suburban homes within 25–35 miles of local broadcast towers, its rigid 330 × 65 mm matte-black dipole bar captures uncompressed 1080i HD and NextGen ATSC 3.0 signals across Hi-VHF (174–230 MHz) and LTE-filtered UHF (470–608 MHz) with rock-steady Signal-to-Noise Ratio.
Clean Matte-Black Living-Room Profile: Crafted from rigid, non-reflective matte-black ABS polymer weighing only 118 grams (3.2 mm wing thickness; 14 mm at the sculpted central U-hub), SignalBar never curls off sunny window panes like paper leaf stickers. A smooth 10-foot triple-shielded black coaxial cable is strain-relief molded into the center hub, paired with an included machined silver F-type female-to-female barrel coupler if you ever want to extend your cable run.
30-Day Channel Scan Trial & 2-Year Warranty: Because brick walls, tree cover, and tower directions vary by street, every SignalBar order comes with a 30-Day Money-Back Home Trial and a 2-Year Hardware Replacement Warranty. Try two window or wall placements, scan your local channels, and enjoy four full weekends of live broadcasts completely risk-free.
Free 5–7 Day US Shipping: Every order ships free with full tracking and delivers in 5 to 7 business days.
30-Day Trial: Try it at home for 30 days risk-free. Need help? Email us anytime at support@buycosari.com.
2-Year Warranty: If anything goes wrong within 2 years, we replace it free of charge or refund your order in full.
Stop paying $83–$135 every month just to keep Sunday afternoon football, awards shows, and 6:00 PM storm radar. Over-the-air network broadcasts are legally free in every US market.
Inline $1 USB boosters cause 80% of metro signal blackouts by overdriving your TV's internal tuner. SignalBar's passive 75-Ohm U-hub keeps strong local towers crystal clear.
Thread the silver F-type tip onto ANT IN, press the slim matte-black bar high onto a window or behind your TV, and run your TV's Auto Channel Scan—done in under 180 seconds.

Thread the silver F-type coaxial plug finger-tight onto the round ANT IN port on the back of your TV. No tools, USB ports, or wall outlets needed.
Press the lightweight matte-black SignalBar horizontally onto an exterior window pane, high along the wall behind your TV, or flat beneath your soundbar.
Open your TV Settings, choose 'Antenna / Air' -> 'Auto Channel Scan', and watch free local HD networks and bonus subchannels populate automatically.
Very pleased! This is a great little antenna. I stuck the slim flat strip high on the wall beside a window and picked up local channels I honestly thought were lost forever.
I was really surprised by how well it worked. I got several channels on an interior wall, then even more after moving it to an exterior-facing window. Other indoor antennas I've tried barely found anything.
Everything about this antenna, I give a five star. Could not be happier. I screwed the silver connector into the TV, ran a channel scan, and now I have free television.
I love this! It was very easy to install and pulls in more channels than my old bulky rabbit-ears cage antenna. The thin matte black bar and low-profile center hub practically disappear, and everything comes in crystal clear.
I purchased this antenna yesterday and was blown away by how well it worked. After trying two window positions and rescanning, we got 21 channels. For a tiny one-time cost, we now have plenty to watch.
Absolutely love this flat black strip antenna. I've bought others trying to save money and they never worked well. This one is a beast, an absolute champion. I'm getting over 58 channels in my upstairs bedroom.
Works as advertised with a great HD picture. My Samsung Smart TV found 80-plus channels, including crisp, uncompressed ABC, CBS, NBC, FOX, and PBS broadcasts from roughly 20 to 30 miles away. Looks indistinguishable from cable without the monthly bill.
I didn't want another monthly subscription, so I tried this instead. The long attached coax made it easy to test a couple window spots before scanning. We now receive ABC, NBC, FOX, and quite a few smaller local stations.
Setup could not be cleaner. There is no USB power cord or inline injector box to hide, just one smooth black coax cable running from the raised center hub to the TV. Exactly what I wanted for the kitchen.
I was worried a compact flat antenna might miss our VHF ABC station. I placed the horizontal black wings high on a window, rescanned, and ABC locked in cleanly along with its local subchannels. No dropouts so far.

No internet or Wi-Fi is required at all. Any television manufactured for the US market since March 2007 with a round threaded 'ANT IN' or 'CABLE/AIR' coaxial port on the back has a built-in digital ATSC tuner ready to scan free local channels.
Both. Unlike square palm-sized sheets optimized only for UHF, SignalBar's 13-inch (330 mm) rigid horizontal wings are tuned across both 174–230 MHz (Hi-VHF) and 470–608 MHz (UHF) so major VHF networks like ABC, NBC, FOX, and PBS lock in cleanly.
Zero power cords needed. SignalBar uses a 100% passive 75-Ohm impedance-matching balun inside its raised central U-hub, meaning only one smooth black coaxial cable goes to your TV—preventing tuner overload and eliminating USB cord clutter.
SignalBar features a permanently strain-relief molded 10-foot (3.0 m) smooth black coaxial cable to eliminate loose-connector signal loss at the head, and includes 1 machined silver female-to-female F-type barrel coupler in the box so you can easily attach any standard RG-6 extension cable.
Yes. NextGen TV (ATSC 3.0) 4K and Dolby Audio broadcasts transmit on the exact same VHF and UHF radio frequencies as standard HD broadcasts—so if your TV includes an ATSC 3.0 tuner, SignalBar receives them automatically with zero upgrades.
Every home's sightline is unique, which is why every order includes our 30-Day Channel Scan Home Trial. Test SignalBar on a window or wall through four full weekends of live sports and local news—if you aren't thrilled with the channels locked in your zip code, send it back within 30 days for a full refund.
