*IMPORTANT TIP -  Indoor Signal Boosters / Amplifiers can work nearly as well as outdoor amplifiers only if the loss between the amplifier to the antenna is low, (up to 50ft of low loss RG6 cable length and without the splitters between the signal amplifier and antenna side (coaxial lightning / surge arrestors or grounding blocks are perfectly fine and recommended along with grounding for some lightning protection).

All splitters, high loss components (note: coaxial lightning arrestors or coaxial grouning blocks are low loss components so won't cause issue) and/or additional RG6 coax cable length (beyond 50ft) should be installed on the "TV Side" (the output connector on the amplifier), otherwise a quality Outdoor Signal Amplifier should be used for a good result. 

*Note that coaxial/antenna grounding blocks or lighting arrestor (devices that add some lightning protection) are low loss components, so these won't effect the performance when installed between the antenna and signal amplifier or the power inserter (if an outdoor signal amplifier), coaxial lightning arrestors along with proper grounding are recommended for some lightning protection and these should be installed per their manufacturer's instructions/NEC guidelines.  High loss components namely refers to splitters.   Splitters are best installed on the "TV Side" (the output connector on the amplifier), if the splitters cannot be moved to the "TV Side" of the amplifier then a quality Outdoor Signal Amplifier should be used instea for a good result.

 

LEARN MORE:

If you have more than 50ft of RG6 coax cable (or 25ft or more of RG59 cable) or feeding your antenna to more than one TV, your install may benefit from a signal amplifier.

This model has 4 x ports of amplification (10db each).  By using the connectors on the amplifier, instead of a non-powered splitter, much of the loss is removed and still have plenty of amplification left over to also restore loss caused by long coax runs.

KEY FEATURES

  • Reliable and precise connection

  • Use with RG6 or RG59 coaxial cable

  • Amplifies VHF, UHF, and FM signals by 10dB


DO YOU TRULY NEED A SIGNAL PREAMPLIFIER/BOOSTER?

A signal booster (or signal preamplifier or just amplifier for short) can make a remarkable difference, but only for specific circumstances (namely when high install loss is dropping the signal).   Although they don't actually increase the antenna's maximum range or change its pattern in any way, they can help the reception by replenishing high install loss that's eating up the signal (if you have high install loss  that needs replenished is key here).  High loss meaning well over 50ft of coax cable and/or if there are any splitters in the coax line (as these will drop the signal if not preamplified), but otherwise they generally aren't beneficial.  This of course also asume's the TV's tuner and coax cable used are working properly.  

If your install loss isn't that high, they may not make any difference at all.  They also won't push the signals through tree or home materials that are blocking the signals (sometimes they provide this illusion, it's actually replenishing high install loss that making the dfference)..  The only effective way to remove the object obstruction in front of your antennna is to change mounting spots or adjust height however. 

Signal amplifiers (also referred as signal boosters or preamplifiers) mainly assist with signals that are dropping due to splitters in the line and/or long coax runs (over 50ft of RG6 coax  cable).  If your install doesn't have either splitters or a long coax run, they generally aren't effective.

However they can still improve reception, by alleviating high install loss (i.e. longer than 50ft of RG6 coax cable, or any splitters / feeding to multiple tVs). 

However if your install loss is low, and the TV's tuner is working correctly to spec, they tend to make no difference whatsoever.  Generally at least 3db of loss is necessary to show improvement (ex: approx 50ft of RG6 coax cable or a 2 way splitter is approx 3db of loss, additionally having both 50ft of cable and a 2-way splitter would be approx 6db of  install loss)

*Note:  Sometimes old, corroded cable (sometimes happens due to  moisture inside the cable) or a weak/faulty TV / tuner can sometimes be bad enough that a signal amplification is needed.  The best remedy if you have bad / corroded coax cable or poor TV tuner, would be to replace the bad coax cable, TV or TV tuner if they're faulty however.

Works great, keeps the light out of my eyes and easy to put together
Size: 1 Panel, Size: 1 Panel
I got this room divider in and it works great. It’s really easy to put together you don’t even need tools. I really like that it’s not see through, it’s not a black out curtain but it keeps light out pretty good. I absolutely hate my bedroom layout there’s no bathroom door. My girlfriend and I have different work schedules so I’m trying to sleep while she’s getting ready for work and the light shines right in my eyes. This divider keeps the light out of my eyes and that’s exactly what I was hunting for. I also like that you can adjust the length. I took one of the bars out to make it a little shorter and it worked great. I would recommend this room divider.

Versatile Room Divider With Easy Assembly and Strong Coverage
Size: 3 Panel 12FT W
I picked up this Siebwin 3-panel folding room divider mainly for privacy and room separation, and overall it works very well. Assembly is very straightforward, and the divider can be set up, taken apart, and stored without much effort. The fabric quality feels good, and the frame construction is stronger and more stable than expected. The support tubes especially feel well built and help keep the divider standing securely. One feature I really liked is the flexibility of the design. The panels can be used together as a complete divider or separated depending on the setup and available space. That makes it much more versatile for different room layouts or temporary privacy needs. The coverage is also very good, and the size matches the manufacturer’s description accurately. The fabric blocks light and background visibility well enough to provide solid privacy without feeling overly heavy. The wider feet also help improve stability compared to thinner folding dividers. Another positive detail is that everything arrived complete with no missing parts or damaged pieces, which made assembly much easier and faster. Compared to cheaper privacy screens, this one feels more durable and easier to customize depending on the situation. In terms of value for the money, it feels like a very practical and worthwhile purchase considering the size, flexibility, and build quality. Overall, a versatile and well-built room divider with easy assembly, strong privacy coverage, stable construction, complete included parts, flexible panel configuration, and excellent everyday functionality.

Stable, flexible in deployment configuration, creates true privacy and looks great.
Size: 3 Panel 12FT W
This is the second room divider panel I have installed, and there are several features about this one that I like much better than my older one. The fact that there are no gaps and that the material is thicker means you get more privacy or more hiding power, if you wish. My older divider has vertical spaces between each of the panels and the panels are half as wide as the Siebwin panels, so there are many vertical spaces. The Siebwin divider really creates privacy. Another feature that I really appreciate is that the legs are wider and stand off from the floor. On my older one the legs are flat and they're rather awkward to adjust because they create more drag on the floor. The feet on the older one also loosen if you turn them counter clockwise, so adjustments of configuration that require the feet to be moved are more complex. The older divider also must be deployed in a zig-zag fashion because he feet are not as wide, but this new one can be deployed and stable in a straight, an "N" shape or an arc. They are both the same length, but because the older one must be use in a zig-zag deployment it doesn't reach to the length of the new one. The Siebwin divider definitely costs more at $103.48, but it sports several features and advantages over the other brand, so it does a better job and is worth the extra cost.

Easy to assemble, does the job, material is shiny nylon and shows creases, minor defects, sloppy
Size: 3 Panel 12FT W, Size: 3 Panel 12FT W
The Siebwin room divider is a good idea, and for the price, it mostly delivers on the intended functionality. I ordered the 12 foot, 3-panel version mainly to hide an unfinished basement storage area that had become an eyesore. It works well for that purpose and gives the space a cleaner appearance without spending the kind of money that more decorative dividers or custom partitions cost. If you need something temporary, portable, or mainly functional, this is a viable option. There are a few limitations that became obvious during setup and use. The first thing I noticed was that the weld quality on some of the metal poles is fairly sloppy. Once the cover is installed, you do not really see it, but up close, it does not look especially refined or professional. The blackout material also is not a matte canvas style fabric as I expected. It has more of a shiny nylon appearance, and the creases are fairly visible. Being that it’s more of a nylon, I’d be hesitant to try steaming it to remove the creases. However, the creases do not matter if you are using it in a basement, dorm, or shared room, but for photography, video work, or a professional office setting, the appearance could be disappointing. The fabric is thick enough, though. It blocks visibility well enough, but strong light behind it still shows through to some extent, nothing deal-breaking. Also, my fabric appeared to be slightly defective. The hook and loop strip on one of the bottom sections was off-center and couldn't be totally attached because it was lined up with one of the legs. I originally hoped to use this as a video backdrop, but I will probably end up replacing the fabric with a proper green screen or canvas material while continuing to use the frame itself. For now, it does a good job of covering my basement junk. Assembly was actually easier than I expected and took roughly 15 to 20 minutes. The longer vertical poles are tethered together similarly to tent poles, which made setup straightforward and fairly intuitive. The shorter horizontal pieces slide and snap together to the top and bottom of the vertical assembly. After each section is assembled, the divider panels connect together with metal plates and two knurled screws (at the top and bottom), so no tools are really required. A few screws were difficult to start because paint had gotten into the threads, but once they caught, they tightened down normally. The feet install with similar knurled fasteners and help keep the divider reasonably stable. One thing to watch for during setup is the fabric orientation. There is one arrow indicator in the middle of the fabric to indicate up. However, if you need another indicator, the smaller hook and loop strip goes on the bottom while the longer strip goes on top. I realized mine was upside down right before finishing and had to redo it. I wasn't difficult to redo, despite the defect in mine. The overall design is practical and easy to move around. I do like that the panels can fold and bend into different shapes depending on the space. The widened feet help stability, although when trying to stretch the fabric tight, I noticed the poles sometimes wanted to overlap slightly at the joints. Tightening everything helped somewhat, but it still happened occasionally. The divider feels adequate for normal indoor use, though I would not expect premium durability or luxury-level fit and finish at this price point. The entire device can also be easily disabled and stored in a tote if you need it completely out of the way. It comes with assembly instructions, but even if you didn’t have them, it’s easy to build without them (save a mistake or two). In terms of value, I think the Siebwin divider mostly matches its price. Around $100 gets you a large freestanding partition with decent usability and easy assembly, but there are compromises in materials, appearance, and refinement. The defects are also off-putting, but hopefully you won't have them. Higher-end room dividers can easily cost two or three times more, so some of the tradeoffs are expected. I also noticed cheaper alternatives online, but based on the quality here, I suspect those would probably have even more issues. For practical home use, temporary privacy, hiding storage areas, or separating shared spaces, this is a good option as long as expectations stay realistic.

Works well but takes up more space than expected
Size: 2 Panel 8FT W, Size: 2 Panel 8FT W
This room divider does the job for creating a little extra privacy and was easy enough to set up. The panels feel decent quality and the wider feet help keep it more stable than some cheaper screens I’ve tried. My only issue is that it takes up a bit more room than I expected, especially with the feet sticking out. It’s still portable and folds away nicely, but definitely measure your space first. Overall it works well for separating a room or blocking off an area temporarily. i wish it came in other colors
