DVB-T UltraBoost Review: A $59 Amplified Stick Antenna and Its 120-Mile Range Upgrade

Our verdict

No for most people, because the range claims are not credible. DVB-T UltraBoost is a small stick antenna on a magnetic base with a USB-powered amplifier, and where TV transmitters are close, a simple antenna like this can bring in free channels. But the page sells a "75-120 Miles longer range" upgrade that no small indoor antenna can deliver, the plug in its photos is the European IEC type rather than the F-type on US TVs, and there is no gain or frequency spec. DVB-T UltraBoost scores 2.9 out of 10, held back by range claims and fit.

The short version

• What it is: an indoor stick antenna with a magnetic base and a USB-powered inline amplifier.
• Price: $59 for one on 6 October 2026, with a five-pack for $149 flagged as the best seller.
• Best trait: free local channels with no subscription, if you live near the transmitters.
• Biggest drawback: unrealistic range claims and a plug that may not fit US TVs.
• Our score: 2.9 out of 10.

Pros & cons

The pros are what any working antenna gives you. The cons are about claims, the connector and missing numbers.

How it works

A TV antenna turns broadcast radio waves into a small electrical signal that travels down the coaxial cable to the TV's tuner. DVB-T UltraBoost adds a small amplifier box on the cable, powered from a USB port, which boosts the signal to make up for cable losses and weak reception. The TV then decodes the digital channels. The antenna does not decide which channels exist: your local transmitters do.

1. 01

   Check your signals

   Step 1: Look up your address on the FCC's DTV reception maps to see which stations are strong, moderate or weak.

2. 02

   Connect and power

   Step 2: Plug the coax into the TV's antenna input, using an adapter if needed, and the USB lead into a TV or wall USB port.

3. 03

   Place and scan

   Step 3: Put the antenna high, near a window facing the transmitters, then run a channel scan on the TV.

The page title piles up "High Gain Digital Signal Amplifier Antenna", "DVB-T Signal Amplifier Antenna", "Outdoor HDTV Signal Amplifier", "HDTV Antenna" and "Digital Terrestrial Antenna". The six bullets promise crystal-clear signal with high gain, long range, compatibility with all TVs and channels, plug-and-play, roof installation and USB power.

What the page leaves out

There is no gain in dBi or dB, frequency range, VHF and UHF coverage, cable length, connector type, amplifier noise figure or range for the standard version.

DVB-T and ATSC

DVB-T is the digital TV standard used in Europe and many other regions. The US uses ATSC. Antennas are not tied to a standard, so the name matters less than the connector and frequencies.

Who it's for

DVB-T UltraBoost suits people living near TV transmitters, renters who cannot fit a roof antenna, and buyers in DVB-T countries whose TVs have IEC antenna sockets. If you are trying to get streaming apps on an older TV instead, our AndroidTV review covers a streaming box sold the same way.

• People near TV transmitters who want free local channels
• Renters who cannot fit a roof antenna
• Buyers in Europe and other DVB-T countries with IEC antenna sockets

City and suburban viewers

Strong signals from nearby towers are where small antennas do fine.

Renters

A window-sill antenna needs no landlord approval.

European buyers

The IEC plug fits most European TVs directly.

Who should skip it

Skip DVB-T UltraBoost if you live far from transmitters and expect 75 to 120 miles of range, do not want to buy an F-type adapter in the US, live among hills or deep inside a large building, or want the cheapest working antenna.

• Anyone far from transmitters expecting 75 to 120 miles of range
• US buyers who do not want to buy an F-type adapter
• People in hilly areas or deep inside large buildings
• Bargain hunters, since basic indoor antennas cost less

Can DVB-T UltraBoost really pull in channels from 120 miles away?

Almost certainly not. Broadcast TV signals travel roughly in a line of sight, so the curve of the earth, hills, trees and walls limit reception well before 120 miles, and a short indoor stick antenna has little gain to start with. An amplifier helps a weak signal survive the cable; it cannot create a signal that never reaches your home.

What the FCC says to do first

The FCC's guide to antennas and digital television advises running a channel scan with your current antenna before changing anything, and notes that many antennas sold as "HDTV antennas" perform best on UHF and less well on VHF channels.

What to do: check whether the stations you want broadcast on VHF or UHF before buying a small antenna.

Reception maps

The FCC's DTV reception maps show the stations available at your address, colour-coded from strong to no signal. If your stations are weak or out of range, no indoor antenna will fix that.

When amplifiers backfire

Amplifiers also boost noise, and in strong-signal areas they can overload a TV tuner. What this means for you: if channels break up, try scanning with the USB power disconnected.

The channel logos and 4K badge

The page shows NBC, Fox, PBS, CBS and other network logos plus "4K Ultra HD". Which channels you get depends on local broadcasts; most US stations broadcast in HD.

How much does DVB-T UltraBoost cost, and are the add-ons worth it?

On 6 October 2026, one DVB-T UltraBoost cost $59, with the five-pack at $149 flagged as the best seller. The checkout offered extra-long cabling to 5 metres for $4, an "Amplifier Range Upgrade" to 75 to 120 miles for $9, a USB car adapter for $4 and a 3-year warranty for $5. Basic indoor antennas from general retailers typically cost less.

DVB-T UltraBoost price and bundles

Prices are in US dollars as listed on 6 October 2026. You can check today's packages on the DVB-T UltraBoost order page (opens G Com Pte Ltd in a new tab).

Extra-long cabling

For $4, cable to "a total of 5m (16.4 Feet)", useful for reaching a window. The image shows the parts: stick, magnetic base, amplifier box, USB lead and a round IEC plug.

Amplifier range upgrade

For $9, "the upgraded 75-120 Miles longer range version". The image shows the same antenna in front of a TV. We would skip it; range depends on your location, not a $9 upgrade.

Car adapter and warranty

A $4 USB car adapter. The 3-year warranty costs $5.

Who sells it

The order page names G Com Pte Ltd at 137 Market Street in Singapore, with the email support@g63com.com and a phone number. The footer gives the country as Hong Kong. The page code says charges appear on your card statement as Matrixfze, written in capitals.

Is DVB-T UltraBoost better than a flat indoor antenna or an outdoor antenna?

Not on the evidence. A flat or loop indoor antenna with a US F-type connector and published VHF and UHF coverage is easier to use in the US, and an outdoor or attic antenna is the honest answer for distant stations. DVB-T UltraBoost's advantage is size and the magnetic base.

Choose DVB-T UltraBoost if

You are in a DVB-T country with strong signals and want a small antenna with a magnetic base.

Choose an outdoor antenna if

Your stations show as weak on the FCC maps. Height and size matter more than amplifiers. That is where a rival wins.

How did we score DVB-T UltraBoost?

DVB-T UltraBoost scores 2.9 out of 10: claim accuracy 0.3, build durability 0.7, price competitiveness 0.4, usability 1.1 and owner satisfaction 0.4, each out of 2. It is a compact antenna with a handy magnetic base. The score falls on a 75 to 120-mile range claim, a European plug for US buyers, no gain or frequency specs and a price above basic antennas.

How the score breaks down

We use the five criteria on our how we test page, each out of 2.

What owners say

We found no Trustpilot profile for the gadgetxaura.com store and no retailer reviews for DVB-T UltraBoost by that name. Owners of similar small amplified antennas report good results close to transmitters and disappointment further out, especially with VHF channels.

What we did, and did not, do

Nobody on our team has used DVB-T UltraBoost. We read the offer page our link opens and its page code on 6 October 2026, along with FCC antenna and reception map guidance and the pages that rank for DVB-T UltraBoost. The refund and returns terms are as we recorded them from the site's terms page on 4 October 2026.

How to use DVB-T UltraBoost for the best reception

Put the antenna as high as you can, near a window that faces your transmitters, and rescan channels after every move. Try scans with and without USB power to the amplifier, keep the cable away from power leads, and rescan every few months as stations change frequencies.

1. Check the FCC maps. Note the direction of your stations.
2. Go high. Upper floors and window tops work best.
3. Face the towers. Window sills on that side of the house.
4. Rescan after each move. Small shifts change results.
5. Test the amplifier on and off. Keep whichever finds more.
6. Avoid metal blinds and foil windows. They block signals.
7. Rescan regularly. Stations sometimes move channels.

Using a metal surface

The magnetic base grips metal window frames or a fridge top, which can also act as a small ground plane.

Fitting a US TV

Screw an IEC-to-F adapter onto the TV's antenna input if the plug does not fit.

What else do people ask about indoor TV antennas?

Most questions are about which channels, how many TVs and whether it needs Wi-Fi. Channels depend on local broadcasts, one antenna serves one TV unless you add a splitter, and antennas need no internet. Browse our tech gadget reviews for more.

Does it need Wi-Fi?

No. Over-the-air TV needs only an antenna and a TV tuner.

Can I connect two TVs?

With a splitter, but each split weakens the signal.

Is it really free?

Over-the-air broadcasts are free where you can receive them.

Can I use it in a car or RV?

Only with a TV that has a tuner, and reception changes as you move.
