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 Mohu Jolt Amplifier makes picture quality clear and vivid, and can even pull in channels outside your antenna's range, resulting in better performance from your antenna. The Jolt can be powered using the USB port located on the back of your TV. The amplifier will only draw power when the TV is turned on, eliminating power consumption - exactly how an amplifier should work. 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.

    It works

    Posted by Scott on Apr 20th 2020

    We live outside Denver's "official" broadcast area. When we decided to ditch satellite and go with broadcast TV, we had a hard time getting good reception on most of the channels (and couldn't get some of them at all). When we got a Mohu antenna, it was a total game changer. But we still have a couple of major channels that pixelate under some circumstances, so I was eager to try this Mohu amplifier. So that we could judge if the amplifier helped or not, we did a channel scan without it and got 27 channels. We also took note that a couple of those pixelated very badly (low-powered stations; the major stations that sometimes pixelate were coming in okay today). Then we installed the Mohu Jolt and ran the channel scan again. This time we got 33 channels. This is clearly an improvement. And the channels that were pixelating now came in clear. Based on just these two points, I can say quite definitively that the Mohu Jolt works. The Mohu antenna works so extremely well by itself, I don't think there was much room for improvement. So, for us, the Jolt wasn't terribly helpful (the extra stations it pulled in are stations we don't want, anyway). But someone who doesn't have a leaf antenna would probably see a much greater improvement. I notice that Mohu now also sells a leaf antenna with a built-in amplifier. Since that doesn't cost much more than just this amplifier, if you don't already have a Mohu antenna, that would probably be the way to go. (Posted on 5/19/2014)

    0 to 65

    Posted by M. Gerrish on Apr 20th 2020

    We bought a new television for a bedroom to replace an early model LCD that heated up the whole room and buzzed, although the picture was excellent. That TV was hooked up to a Roku HD and a flat antenna propped in a window to receive over-the-air broadcasts from our local stations. It worked well except for the heat and buzzing issues. New, low-priced TV arrived and I was distressed to discover that for whatever reason, the new TV wouldn't pick up the broadcast stations. None. Not even pixelated. Nothing. I don't know the mechanics of it, but I was almost resigned to the bedroom set being a Roku-only set (not the worst thing), when I remembered that this product had arrived and this was the occasion to try it. Ran set-up again and immediately picked up 65 stations, including all the major networks in our area. Crystal clear. Works for us! (Posted on 5/19/2014)

    I installed my Jolt in 5 minutes on July 3, 2013. This is a FABULOUS product!! It exceded all expectations. Using a high end digital antenna without the amplifier, my new internet ready Samsung TV located 27 channels. About a third of those were unwatchable with squiggly screens and at least one major broadcaster was completely missing. Some of the channels were just junk tv that I don't watch. WITH JOLT I NOW LOCATE 59 CHANNELS INCLUDING SOME MUSIC ONLY STATIONS.I GET ALL THE MAIN STATIONS AND ONLY A COUPLE OF THE 59 ARE SQUIGGLY. ALSO, THE COLOR IS MORE VIVID!! I had to readjust my color settings to tone down the colors due to the enhanced reception! The Jolt is magic in a match box size device! (Posted on 5/19/2014)

    Excellent reception!

    Posted by Doug on Apr 20th 2020

    This product vastly improved our reception for channels that were previously pixelated due to interference. We own 2 Mohu Leafs. I highly recommend this product and especially Mohu's customer service! They are great and always willing to help. Thanks again Lynda! (Posted on 5/19/2014)

    Essential, in my opinion

    Posted by NL on Apr 20th 2020

    I have had the Jolt for about 3 weeks now, having bought it at my local Wal-Mart with the ship-to-store free delivery option. Mine looked like it had been opened, re-packaged, and returned but otherwise seemed unscathed by the experience. Connecting it to my Leaf was simple. I re-scanned the channels on my Samsung, curious to see if I could pull in more of them than the 17 I had already been getting with just the Leaf. I’m not sure how some of the other commenters wound up with all those additional channels; I still got just the 17 from before. And it’s not like I live out in the boondocks someplace, but within 30 miles of a population of 1 million. Anyhow, more channels were not what I was interested in. I wanted to see if the Jolt would solve my problem of having to move my Leaf around the room to keep the picture from freezing or pixillating at certain times. I’m happy to report success but not without having to rescan my TV about 6 or 7 times for some unknown reason. Now I have my Leaf secured in the Mohu stand (please see my comments on this item before you order one!) and for the past 3 weeks I have gotten rock-steady reception on all the channels that use to require moving the Leaf before. Just remember not to give up on the Jolt until you have re-scanned your channels several times, unless, of course, you get everything you need the first time around. (Posted on 10/20/2014)

    At last, An Amp That Works!

    Posted by Carmine5 on Apr 20th 2020

    I live in the rurals and can only receive two channels (yes, we desperately need some translators out here). Even on the good days the signal can fade at times. I have tried all makes and models of amplifiers--from the most expensive to the cheapest in an attempt to pull in a consistent signal. None has performed as well as the Jolt. Under a variety of conditions, including rain, I've been able to get a reliable 68-70 on my DTV's tuner, something which was unobtainable with the other amplifiers. Save yourself the trouble of fiddling with different amplifiers. Just get the Jolt. (Posted on 7/17/2015)

    The amplifier adds extra channels and makes them stronger. (Posted on 9/3/2016)
