Do you ever find that your TV antenna needs a boost? Look no further! The Jolt is a revolutionary digital antenna in-line amplifier designed to amplify TV signals and filter out any RF signals that can hinder picture quality. The Jolt allows you to receive a clearer picture, more TV channels, resulting in better performance from your Leaf antenna. The Jolt can be powered via a USB port located on the back of your TV. The amplifier will only draw power when the TV is turned on, eliminating power consumption. If you do not have a USB port on the back of your TV, a USB power adapter is included to power the amplifier using any standard wall outlet.

    The Best Digital TV Antenna Amplifier on the market

    Posted by Terrell Jones on Apr 20th 2020

    The Jolt Digital TV Antenna Amplifier is the best Digital TV Antenna Amplifier on the market. Combined with the Leaf Antenna, it really pulls in the strongest possible signals. I bought it for my Grandmother who currently owns a leaf plus. Even with the leaf plus, her kitchen TV could not pull in a strong signal. It all changed with the Jolt. The Jolt pulled in all of the stations that the leaf Plus could not. We both are very happy and will recommend this product for people who want to are thinking about cutting the chord.

    The antenna worked as advertised and I did receive 10 or more additional channels

    Posted by Ransom on Apr 20th 2020

    I received the Mohu antenna amplifier and was advised by the customer service department that it would work on any unamplified antenna. I have an Antennacraft 1850HD antenna on a roof mount, and I knew that there were more channels that I could get with an amplifier. I did re-scan my television and pulled in additional channels that were broadcast from Raleigh Durham, Greensboro and Lexington N.C, and I am approximately 60 to 70 miles from these broadcast stations. Overall, the Mohu antenna amplifier worked as advertised and it is an excellent addition to a DTV installation at the price it is advertised. (Posted on 5/19/2014)

    Great antenna preamp

    Posted by Azen on Apr 20th 2020

    I have been a fan of Mohu for almost two years now as I have not had cable in my apartment and was just streaming until I got a Leaf. I am not home much and most of what is on cable I can get with my Smart TV apps. I now have two Leaf antennas in my apartment, one in the living room and one in my bedroom. I live in Manhattan and get 78 channels on one and 71 on the other. I probably would get more with this amp but I don't really need anything more than I already receive. However, I did get two Leafs for my parents in Garden City so they could return two of their cable boxes in the basement and the guest bedroom. Garden City is about 20 miles outside of the city and they get about 25 channels with their two antennas. However, according to my mom, if it snows or is super windy the signals pixelate and even cut out for a second or two. I was going to get them two Ultimate but then saw this thing. So, the point of the review is that I got them two Jolts, shipped from J&R and got to their house in two days. I set them up last weekend and they are now getting 45 channels on each of the two televisions. Pretty sweet. The Jolt's actually look like the images and have some sort of soft touch finish on them. They look expensive and it a shame they sit behind a television. I am not sure if the "Cleanpeak" filtering is applicable because they are not too close to any towers (if anyone is, I am on 63rd Street) but the 15dB of gain has given them more channels. I have to wait and see if the reception is going to be more consistent but I imagine it will be. Definitely recommend this product if you need to amplify your leaf or any other antenna you have although from Mohu's web site this is not meant for a Leaf Plus as its already amped. Five stars as they now have two tv's powered with 45 channels for about 200 bucks. Next stop is my grandma's Christmas gift. Mohu seem to have their act together. (Posted on 5/19/2014)

    More than tripled our channels in a rural area

    Posted by btn on Apr 20th 2020

    We live a rural area outside of Albuquerque. With a pair of seven dollar rabbit ears we were able to pick up 7 channels, but two consistently pixilated and cut out. With the same rabbit ears and the Jolt we are able to receive 22 channels. Granted, some of these are channels that I can certainly do without (preachers with big hair and clown makeup, shrill people selling junk...) but the Jolt does pick them up. The two that pixilated prior to adding the Jolt are much improved, one channel is now perfectly fine, and the other has only occasional jitters. Keep in mind you A) do not use this with an already amplified antenna and B) it does require power. It comes with a usb wall charger and the usb cord. However the cord is pretty short (about a meter or 3 ft). Newer TVs may have a usb port in them, my older one does not. For us, this is a significant improvement, but it seems that your mileage may vary, in an area with already strong signals perhaps the difference is not as great. (Posted on 5/19/2014)

    Has me taking a second look at the "Leaf"

    Posted by Lex on Apr 20th 2020

    Ever since our household found Netflix, Hulu, etc. and "cut the cord", shopping antennas has been a minor obsession. We've found some doozies, including this beauty: Terk HDTVa Indoor Amplified High-Definition Antenna for Off-Air HDTV Reception. (Seriously, you have to look. It's a huge 1930s Sci Fi movie death ray, on top of our kitchen TV/computer setup!) What we had not given so much thought, was amplification. And I guess we should have, in retrospect - the Mohu Jolt has opened my eyes, in that regard. I'm not going to say that it has magically delivered a bunch of new channels to our home, although obviously it has, for some. For us, what it HAS done is strengthened the signal appreciably for many stations (no more signal cutting out when someone shuts the door to the next room!), and made it possible for us to watch our (3) local PBS stations without anyone needing to stand on one foot like a flamingo while touching the left rabbit ear. So yes, now I'm wondering what that ridiculous looking Mohu Leaf Paper-Thin Indoor HDTV Antenna - Made in USA might further do for our off-the-air reception. You know, if we can bring ourselves to relocate the death ray device. Footnote for the technically disinclined: I tend to delegate hardware tasks of all sorts to my spousal unit, but set up the Jolt myself and it was easy peasy: unplug the antenna from the back of the monitor/TV, plug in the identical connection on the Jolt there, then plug the power supply into the TV's USB port (or the wall, via the included AC adaptor, if you don't have an available USB port on your set. Seriously, it took twice as long to write this paragraph as it did to set up the amplifier. Weird and wonderful, to not be constantly, incrementally adjusting the antenna anymore.

    I can't believe it but it works

    Posted by Kha on Apr 20th 2020

    We currently have 3 TV's in our house. All of them hook up to a small over the air antenna. We sometimes watch our local over the channels like KQED. But after trying three different antennas, none of them work as advertised. We would be able to get some channels sometimes but always seem to have problems. My mom watches our local ethnic channels but out of the 7 available we can only get 1 reliably with the antenna that we have. Anyway when hook the Mohu Jolt in I was very skeptical since my antenna already have a built-in amp. But after playing with it for a while I notice I'm getting most if not all of the local ethnic channels. WOW, it works ! If this keep up I have to two order two more for our other TV's. So far I'm very happy with it. (Posted on 5/19/2014)

    Added it to my Mohu Leaf and got a few more stations

    Posted by Rox on Apr 20th 2020

    I like Mohu's product and like the Leaf, the jolt is a straight forward product that is easy to install. I love that you have the USB connector option (what I'm using) so I'm not using one of the few plugs in the TV room. The Jolt installs in minutes and only requires a re-programming of the digital channels. I got about 10 more digital channels added to the lineup including ABC and (sometimes) NBC, but because of the area I live in, we don't have more options. I was hoping to get a few more local news channels since we don't have cable, and we did. However, the signal still comes and goes and some new channels aren't "sticking." I like the product, and I think it would be a better fit for someone in an Urban area with lots of digital channel choices. (Posted on 5/19/2014)

    Mohu Jolt HDTV Antenna Amplifier

    Posted by Ama on Apr 20th 2020

    I have tried this on two TVs, each hooked up to a different type antenna. While it didn't help lock in any channels that were unavailable without it, it did clean up the signal on a few problematic channels on each set (different channels on each set due to antenna type and location). I left it installed on the TV we use the most, which is hooked up to a directional roof-top antenna. All the channels that I get come in clean now. The other TV I tested it on was connected to a leaf style antenna and a digital to analog signal converter. When connected between the antenna and converter, it also improved the reception of a couple problematic channels that were pixelated or only came in about half the time. (Posted on 5/19/2014)

    Mohu has best technical customer support ever!

    Posted by A Dixon on Apr 20th 2020

    Antennas are such a complex thing to shop because the exact same antenna will get different results in different places and on different days even sometimes! But what I have found consistently true is what great technical customer support you get from the Mohu CSRs! They really know their stuff! This Amplifier is to boost the original Leaf to the power of the Leaf Plus. If you already have the Leaf Plus, this amplifier is already built in and while in America we think more is always better, when it comes to sound waves, it is not. Too much sound waves creates interference and you will get poorer results. Who doesn't want the best audio and video quality possible? I suggest a call to the Mohu technical support to find out if this Mohu Jolt HDTV Antenna Amplifier is the right fit for you; if it is, I can not say strongly enough how well-made and high quality it is but what is most impressive is that you can get sophisticated technical support from English-speaking CSRs on the telephone that really know their stuff! Impressive! I recommend Mohu products including this one if it is the right fit for you. (Posted on 5/19/2014)
