THE CIMPLE CO Antenna Amplifier Kit, Digital TV Signal Booster with Coax, Adjustable Gain, 24 dB Distribution, NTSC, ATSC, FM, UHF, VHF, 1000 MHz, Includes RG6 Coaxial Cable, Indoor Use Only

I am so impressed with The CIMPLE CO Antenna Amplifier! It has made a noticeable difference in my TV reception. The adjustable gain feature allows me to fine-tune the signal, ensuring I get the best quality picture and sound, even in areas with weak signal strength. The 24 dB distribution works perfectly for my needs, and I love that it supports a variety of signals including NTSC, ATSC, FM, UHF, and VHF. The included RG6 coaxial cable was a nice touch, making installation quick and easy. Since using this amplifier, I’ve noticed a significant improvement in both the number of channels I can access and the overall clarity of the signal. If you’re looking for a reliable and affordable solution to boost your antenna’s performance, I highly recommend this product!

I used this to boost a transmission signal and it works very well. Nice solid metal body construction and good quality coax cable and power supply included. I like the output power adjustment knob, it seems to be responsive and not flimsy. It might be nice to also include a physical on and off switch as well, otherwise very pleased.

This signal amplifier is fantastic. It works so well at getting our living room TV more clear channels, we ordered two more to put in a bedroom and the basement. (If it were logistically possible, I'd just put one on the line-in, but this works too.) We're out in the rural'ish exurban outskirts of a metropolitan area. Weather events like wind and rain, and even the leaves on the trees in the summer, impact reception. With this amplifier, everything becomes stable and clear. The same signal that at times produced iffy reception after going through the house's coaxial cable infrastructure, is now amplified to produce channels we didn't before have available. Public television is now watchable! 60+ channels are watchable and clear on a regular day. That's pretty good for our area! I also suspect that the additive properties of having 3 of these might be clearing up signal even more in some unknown way. I'm writing this glowing review, because I've tried so many varieties of gimmick amplification devices, and most of them did nothing. There is a lot of garbage out there. This, however, is the real deal. It works. It produces an overall improvement in signal strength, and it's measurable. This is the one. It doesn't seem to produce much if any heat, either, which is fantastic when you consider this might get installed on a wall somewhere-- and it has built-in mounts to do so. I'm not using the mounts, but am glad they're present.

I don't have time to go on and on about this, but very much want to share that amidst the dizzying array of questionable products from overseas offered, and questionable reviews, I managed to select this distribution amplifier and I am super happy with the purchase so far. It just worked out of the box for my application. Excellent quality, I hope it lasts. I noticed a lot of confusion in the Q&A on Amazon for these types of products. I'll share quickly what I learned. I purchased an amplified antenna on here (https://www.amazon.com/gp/product/B09J1X2J3S), which also works great as a fixed pointing ATSC TV antenna on my roof. My wires all go to my basement, including all the coax to all the room outlets. So, the antenna control box and power injector must be at the other end of the cable from the roof in the basement. That powers the amplifier on the roof (this is a "Preamplifier", meant to amplify the weak signal off the air), which boosts and drives the signal through that long wire to my basement. The control box puts out a lovely TV signal, but that only works for a nearby TV. How, then to get that signal to all the TVs on the other ends of all the coax ends in the basement? That's where this product comes in--a "Distribution Amplifier". meant to take a strong signal and make it stronger so that it can push through a splitter (power divider) and then through more long cables through the house to all the TVs. This product has one output, if you have more than one distant TV you need to run coax from this box to a splitter (1:2, 1:4, 1:8, etc.), and connect all the coax cables to the splitter. Don't use more gain in this product than you need. I find I need the max gain pushing through my 8:1 splitter and long cables. That's it, good luck!

I was using an 18dB amp that came with an external antenna, basic plastic thing, that seemed boastful at 18dB, it was pretty weak. Temporarily using this antenna indoors for testing as I set up my new house. Figuring if it can do well inside, it will almost certainly do better when I mount it high up outside. This amp being 6 dB more at 24dB did the trick for FM signal. Cleared up the bits of static in the signal right away and I picked up a couple stations that would not lock on stereo loud and clear. I have it cranked all the way, but when I backed it off a bit, signal was still good. Have not used this one yet for HDTV/Off air channels, but original amp actually handled this frequency segment well enough, it was more the FM Radio signals I was trying to boost. Radio signal can be tricky, radios with built in antennas placed upstairs in one corner of the house are all good, downstairs in the opposite corner...static, weak, won't grab some stations at all. I went around with a battery powered radio outside and inside and found the sweet spot locations, but it's really about the number of walls, etc. between the radio and the tower transmitter out there. I live in a more remote area now and am sort of old school, I like having good old FM radio available for NPR and any radio stations I can pick up. This did the trick. I'm using apps more on smart TV's for some stuff...still wanted good strong FM/TV antenna infrastructure at the ready. I'm considering adding a second amp in line to boost the heck out of the signal, probably don't not need it. Previous owner had satellite TV (shudder, ripped that out immediately), so in house cable distribution is all over the place in virtually every room. Will take advantage of this for TV/Radio now as it's any easy swap/add. Some negative reviews here had me scratching my head, sounded like they might have hooked it up wrong or have a weak antenna/poor placement? Or it could be defective I suppose, but there is not much to fail with this basic amp. This amp does appear to have every bit of the power described. I've tried it with a smaller window mount antenna and a large modular exterior antenna (again temporarily inside), both had good to great results respectively. General rules of thumb: -Place an amp as close to the antenna as possible, this can make a big difference. If you place it way down stream of long meandering wire runs and splitters, might not perform as well. -Some even mount the amp right to the antenna pole outside and run power to it or an amp is integrated in the antenna. If you are within about 20 feet to the amp from antenna, should be all good. -You can stack amps in line, to push that dB power up there, although I doubt most people will need this. -If you are using existing coaxial cable TV infrastructure (and you are using cable TV boxes still over smart TV apps), caution when loading up amps in line with it, generally it's fine to share signals here, but too much can interfere with one signal or the other. Plus if you have cable TV, you probably don't need an off air antenna for HDTV/Local channels anyway. -Survey around the house for best antenna placement. -Invest in a quality antenna, remote steerable ones are really cool for dialing this in.

Works Ok for close TV signals. But it costs more than a cheaper model and does not do any better job of reception gain.

I have a TV in a far off bedroom from the exterior antenna and the attic signal splitter so reception in this room was poor. I connected the booster amp directly to the TV and got way better reception. I do need to move it closer to the antenna and signal splitter up in the attic so it will improve reception elsewhere in the home. Easy to hook up everything is included.

Unfortunately this tv amplifier didn’t work for me. After numerous turn adjustments to my antenna’s direction and amp tuning, I actually lost 2 local channels (2[fox] & 5[cbs]) and pixelation of some channels were still present. I did however gain a few more channels but they were not relevant gains to me since they weren’t of interest to me based on the shows they were broadcasting. I live in the suburbs and about 45 miles from nearest broadcast towers according to the online tower locator map if that makes a difference. However, this item looks to be well built and depending on your equipment and relative location to broadcast towers this may work for you but it didn’t work for me so returning it.
