Antennas Direct ClearStream Eclipse review: a cheap but powerful amplified indoor antenna | TechRadar

Feb 21, 2025

An almost-flat, window- or wall-mount design with impressive signal-pulling abilities, the ClearStream Eclipse is powerful, yet priced lower than much of its higher-end indoor antenna competition.

Strong range

Included signal amplifier

Reversible for white or black surfaces

Free Antenna Point app

Must be affixed to a flat surface

Supplied cabling may not be long enough for some setups

The Antennas Direct ClearStream Eclipse is a simple, yet powerful indoor antenna with an unobtrusive design. Like other examples of the best indoor TV antennas, its only function is to “pull” the stations you want at your particular location. Still, until you try a given model at yours it’s impossible to predict the results. That said, Antennas Direct makes it a bit easier with its free Antenna Point iOS/Android app, which uses your phone’s location data to display a map showing transmitter locations, and thus your aiming direction, and lists all their main and sub-channels sorted as Strong, Fair, or Weak (based purely on distance, with no considerations for elevation or obstructions, but it’s a start).

The Antennas Direct CleStream Eclipse’s packaging claims a “50-plus-mile range,” but remember that any antenna’s performance is largely dictated by its elevation and by the presence or absence of intervening hills or tall buildings. Note that this review also covers the amplified Eclipse: the same antenna is offered without the signal amplifier for about $15 less.

The Eclipse antenna is a flexible vinyl halo about 8 inches across, meant to be fixed to a smooth surface — typically, a windowpane or painted wall — using the supplied crescent of clear double-sided adhesive plastic. (Since my trials were strictly temporary, I used blue painter’s tape instead, and suggest others do likewise until they finalize their installation.) One side of the antenna is white, the other black, so decor-wise you can pick your poison.

A housing at the bottom about a half-inch thick — the antenna itself is not much more than a half-millimeter or so thick – provides a standard coaxial F-connector plus the supplied coax cables. ClearStream packs two: 3-foot and 12-foot lengths, intending the shorter one to connect the antenna to the included signal amplifier, and the longer one to the amp to your TV (other lengths are available at most hardware stores). The amp module, about the size of a pack of gum, has two F-connectors (antenna input and signal output), and a mini-USB port for power. A supplied 8-foot power cable supplies the juice, which can come from any open USB port on the TV or another component, or from the small wall charger packed with the Eclipse. (The amp supplied with my Eclipse sample looked slightly different than the one shown in ads, but is likely to be electrically identical.)

Before we report on the ClearStream Eclipse’s performance, it’s worth repeating: real-world reception is overwhelmingly affected by your location’s elevation, and by any obstructions, natural or man-made, that intervene between it and your desired stations’ transmitters. Our results reflect a semi-rural spot at about 700 feet above sea level, in a second-story window with a clear line-of-sight southeast, where a variety of signals emanate from the east, south, and southwest, at distances ranging from 17 miles to more than 75 miles. This is a pretty excellent site, so your mileage will vary.

With that caveat, in my trial the Eclipse pulled in 16 main signals, delivering a total of 61 main and sub-channels combined – impressive results. Of these, the most distant one (nearly 70 miles) was occasionally “blocky” enough to be only borderline usable, while the rest were solid, though this is likely to vary from day to day and even hour to hour as atmospheric conditions change.

With its very fine performance (especially on UHF-band signals), the ClearStream Eclipse Amplified is very fairly priced at $50, and it can regularly be found for less. Nonetheless, spending half to twice as much on a larger design incorporating VHF elements may deliver a few more fringe signals.

You need fringe-suburban to edge-rural reception: The Eclipse managed to pull in signals from 17 to nearly 70 miles in our test setting.

You want an unobtrusive antenna: The Eclipse's surface-mount design lets it easily be hidden in a window or on a wall outside of view.

You need to receive signals much beyond 50 miles: The Eclipse may not be able to pull in signals from long distances, especially if your home is in a low spot or obstructed by hills or buildings.

You need a VHF (channels 2-13) station at some distance: In this case, a larger indoor antenna with VHF elements may well do better.

Mohu ArcA slightly pricier antenna with a decor-friendly design. It lacks amplification, so is best suited for urban and suburban enviroments where stations are within a 40-mile radius.

Mohu VibeThe Vibe is another design-friendly option with good signal-pulling abilities, though its range comes up short compared to the Eclipse.

Winegard FlatWave Amped Pro TH-3000A pricier amplified antenna that provides very good range at 60-plus miles, It also features a useful Bluetooth setup app to assist in installation.

I test indoor TV antennas at a semi-rural, hilltop location with good elevation and a clear line-of-sight over nearly 360 degrees to TV transmitters ranging from about 15 to about 70 miles. This testing environment gives me the ability to evaluate models catering to a full spectrum of indoor antenna needs.

For the testing process, I first place the antenna high up in a south-facing window and run the tuning process on a TV with an ATSC 3.0 “next-gen TV” tuner. I then record the number of carriers tuned, along with the total number of sub-channels. A powerful inside-the-attic rooftop-type antenna at the same location is also used as a reference for comparison.
