Antop UFO 720° Antenna Review

Antop UFO 720 Antenna Review

The omnidirectional UFO 720° HDTV antenna by Antop comes packed with features to get up and running with over-the-air television in no time.

It’s easy to set up, boasting tools-free assembly and includes a preamplifier with 33 feet of RG6 coaxial cable that you can connect directly to your TV or converter box.

Its unique shape and aesthetics make it suitable to mount anywhere, be it inside or outside your home, your RV, or on a boat. Not only does its white color make it low-key and inconspicuous from afar, but it also protects the device’s parts from the UV rays of the sun.



The antenna is omnidirectional, meaning it receives signals from 360° around. In other words, given sufficient signal strength, it should pick up any surrounding TV stations.

The reason this antenna boasts 720° and not 360° omnidirectionality is because ANTOP has added a vertical antenna to the design. This gives it 360° reception both horizontally and vertically.

A great way to discover which TV stations you can pick up (and how far away they are) is to generate a signal report from TVFool and match signal strength and tower distance with the antenna you’re thinking of getting.

In this case, the antenna’s nominal range is 65 miles so you should ensure the stations you want to pick up are well within this range.


The antenna also comes with a built-in preamplifier, which ANTOP refers to as the Smartpass Amplifier. This preamplifier boosts the strength of TV signals the antenna receives and should generally increase the number of channels you get.

The antenna has a nominal gain of 20 dB, but switching on the preamplifier should increase this antenna gain to 30 dB (this makes the signal stronger and better able to overcome any loss as it travels down the coaxial cable to your TV). The switch to turn the preamplifier on is conveniently located on the coaxial cable that attaches to your television.

Filtering of Cellular LTE Signals

It also comes with a built-in 4G LTE filter, which ensures that cell phone signals don’t interfere with the UHF TV signals you’re receiving. This filter reduces noise interference from nearby cell phone towers.

Channel and Frequency Types

The antenna supports broadcasts of up to full HD (1080i or 1080p), and 4K. It picks up signals on both high VHF (RF channels 7-13) and UHF (RF channels 14-51).

RF channels are not the TV channels you normally think of, but are otherwise known as broadcast or real channels. They’re allocations of the radio frequency spectrum that stations use to broadcast signals.

It’s important to know which frequencies your antenna can pick up. You can find out the availability of RF channels in your area by consulting

Assembly and Installation

Assembling the antenna is easy, as you won’t need tools to attach the parts. You decide the best place for the antenna by choosing a spot that has the least amount of obstructions in the line of sight to surrounding transmission towers.

You can mount this antenna indoors or outdoors. Some customers put it in their attic or balcony, but many get best results by mounting it as high as possible off the ground.

The antenna comes with a clamp and U-bolts for mounting it on a mast like the Channel Master CM-3090 Universal Antenna J-Mount.

After mounting the antenna, you run the supplied coaxial cable to your set top-box or TV. If the cable is too short, you can extend it with high-quality coaxial like MediaBridge Ultra Series tri-shielded cable and F-type connectors.

Attached to the end of the coaxial is a small switch that I had referred to earlier, which allows you to turn the preamplifier on and off. On the antenna itself you can find LEDs indicating whether the preamplifier is switched on.

After installing the antenna we recommend grounding it. You can find more information on grounding and outdoor antenna in this article.

In case you have more televisions in your home and want to hook these up to the antenna, you can attach a splitter to the end of the coaxial and then run further coaxial cables to your TVs.


  • Receives OTA broadcasts from all sides (omnidirectional)
  • Built-in preamplifier to boost received TV signals
  • Filtering of cell phone signals that could potentially interfere


  • Supplied coaxial cable may not have sufficient length for your situation

Antop UFO 720° vs 1byone New Concept Series

The New Concept Series Omnidirectional TV antenna from 1byone offers comparable features to the ANTOP UFO 720°. Both are small, aesthetically designed, and lightweight units intended for installation in a variety of settings.

One notable difference is the fact that the ANTOP antenna has vertical reception, which the 1byone doesn’t have. In addition, the ANTOP antenna has built-in cellular noise filtering. Otherwise both antennas have matching features.

Our Verdict

The Antop UFO 720° Omnidirectional Outdoor HDTV antenna offers a highly compact over-the-air antenna kit that includes everything you need to start getting free TV.

Convenient to set up and install, it comes with a number of features to booster picture quality, such as built-in amplification and LTE filtering.

Receiving both high VHF and UHF frequencies, you can also install it indoors such as in your attic or at an upper floor window. ANTOP products have a reputation for quality and good value.
