Indoor Multi-Directional Antenna

ClearStream Eclipse and Flex are both indoor multi-directional antennas perfect for your house, dorm rooms, or recreational vehicles or RVs. Setting up these ClearStream antennas are so easy that you do not need to bring out your tools and hardware to install. There are no hooks or Velcro also. The ClearStream Eclipse and Flex can stick to any surface, from drywalls to glass windows. Therefore, you don’t have to poke holes and ruin your walls.

Thinness and Reversible Color

Antennas Direct used the same loop in their outdoor antennas with the ClearStream Eclipse and Flex. The difference with these antennas, aside from being indoor antennas, is their extreme thinness. The ClearStream Eclipse and Flex are ultra-thin at only 1 mm thin. These TV antennas have two sides with different colors. One is black while the other is white, so you have the choice of which side you want to be visible.

There are no sweeter words than ‘Lifetime Warranty’. The ClearStream Eclipse and Flex are backed with a lifetime warranty on their parts from Antennas Direct. Their lifetime warranty is proof that both the ClearStream Eclipse and Flex are great products of high quality and standard.

Differences between ClearStream Eclipse and Flex

Knowing the differences between these ClearStream antennas will make it easier for you to decide if Eclipse or Flex is the right antenna for you. We will explain in detail everything that makes these antennas different.

Design and Assembled Dimensions

Although the ClearStream Eclipse and Flex are both ultra-thin, these TV antennas have entirely different designs and assembled dimensions.

ClearStream Eclipse

The ClearStream Eclipse has more of a ring-like design. Perhaps, this is why Antennas Direct name it this way since it uncannily looks like an eclipse. This circular design reminds me of their more popular outdoor antenna, the ClearStream 2V. The assembled size and weight of the ClearStream Eclipse are smaller at 10″ X 9″ X 1 mm and 4 oz. respectively.

ClearStream Flex

In contrast, the ClearStream Flex has a rectangular design, resembling a blank sheet of paper. It is slightly larger than a legal paper at 12″ X 16″ X 1 mm and weighs more at 6 oz. Personally, the ClearStream Flex has an overall better design due to its simple design that can blend in any wall. You can even place it behind a picture frame to better conceal it. But picking based on their designs depends on your preference.

TV Antenna Range 

The TV Antenna Range of an antenna is an important specification since it indicates what kind of signal reception they can attain. Since obstructions such as buildings and foliage can reduce this range, having a longer TV antenna range is advantageous.

ClearStream Eclipse

The ClearStream Eclipse can receive signals as far as 35+ miles. Although it is already impressive, it does not match with the TV antenna range of the ClearStream Flex. If you need a longer range for better reception, you can get the ‘Amplified’ version of the ClearStream Eclipse with includes a Jolt 15 dB USB in-line amplifier. Otherwise, the 35-mile antenna range of the ClearStream Eclipse is unparalleled in its price range.

ClearStream Flex

On the other hand, the ClearStream Flex is already amplified as it already comes with the Jolt 15 dB USB in-line amplifier out of the box. Therefore, you can expect more than 50 miles of TV antenna range with it. The ClearStream Flex is more expensive, which is something you should consider.

The Winner Is: ClearStream Flex

Radio Frequencies

Ultra High Frequency (UHF) and Very High Frequency (VHF) are the two frequency bands where over-the-air TV signals are distributed.

ClearStream Eclipse

While most TV antennas can receive both frequency bands, there are some antennas designed to capture UHF channels only including the ClearStream Eclipse. The lack of VHF bands makes it harder for the ClearStream Eclipse to capture and detect VHF channels even if you are close to your local broadcast towers. Channels like Fox and ABC are on the VHF bands, so you can miss out on these popular channels. 

ClearStream Flex

You do not have to search and verify the frequency and channel of your favorite TV shows with the ClearStream Flex as it covers both UHF and VHF bands. You will have all the OTA TV channels available with the ClearStream Flex. Therefore, the ClearStream Flex is the safer bet between these TV antennas. Lastly, the ClearStream Flex is 4K ready which is a huge advantage of the Eclipse.

Final Verdict

Looking at both the ClearStream Eclipse and Flex, both are great TV antennas for their price. However, based on this comparison, the ClearStream Flex is undoubtedly the better TV antenna with its longer antenna range and more received channels. All these additional features come with a higher price tag, almost as twice as that of the ClearStream Eclipse. With that said, I can still confidently say that the ClearStream Flex is worth it even with its higher price. You can still save a lot of money buying one of these, rather than paying for streaming subscriptions.
