More channels, cleaner reception

Could your TV antenna use a boost? The Mohu Jolt is a high-performance antenna amplifier that uses patent-pending technology to pull in an impressive number of local channels while filtering out the RF noise that can harm reception and picture quality. Compared to an antenna alone, most people find that adding the Jolt lets them receive more stations, while also producing a clearer picture on stations with less-than-perfect reception. The Jolt works with any non-amplified TV antenna, but it is optimized for use with Mohu's own Leaf antenna. Simply connect the Jolt between your antenna and your TV and start getting more out of the free, over-the-air HDTV viewing experience.

Two paths to power

You can power the Jolt two ways. There's a mini USB port on the amplifier module, which allows you to power the Jolt off of any standard USB port on your TV — the USB-to-mini-USB cable is included. The advantage of USB power is that the amplifier will only draw power when the TV is turned on, instead of 24/7. If you don't have an available USB port on your TV, the Jolt also includes a regular AC power adapter so you can power the amplifier from any standard wall outlet.

Product Research


TV Antenna Amplifier: The Mohu Jolt is a digital antenna amplifier with a low noise figure and RF filtering. Its designed to amplify TV stations and filter out any RF signals that can hinder picture quality. The Mohu Jolt allows you to pull in a clearer picture, more stations, and increase overall performance.

  • Gain: 15 dB
  • Noise Figure: 1.6 dB
  • Output IP3: +37.5 DBM
  • Frequency: 50-800 MHz

RF Connectors: The Mohu Jolt antenna amplifier is fitted with a male F-type RF connector on one end that connects to your TV antenna's cable, and a female F-type RF connector on other end (attached via 11" cable) that connects to the RF-jack on your TV.

USB/AC Powered: The Jolt is powered via a USB port located on the amplifier, which allows you to power the antenna amplifier using an open USB port on the back of your TV. The advantage of doing so is that the amplifier will only draw power when the TV is turned on, eliminating parasitic power consumption when the amplifier isn't needed. If you do not have an open USB port on the back of your TV, the Jolt antenna amplifier also includes an AC power adapter that will enable you to power the amplifier using any standard AC wall outlet.

Did the Trick!

Crutchfield Customer Review (What's this?)

The Jolt allowed us to watch antenna TV with the same quality as cable. The antenna alone didn't work well enough in our area.

Pros: Easy to install. You can use it with a very inexpensive antenna for great results. Be sure to "discover" your channels again in your TV setup or it may appear that nothing has changed.

Cons: Didn't work with the antenna I was using (the Terk) which apparently has its own (not strong enough) pre-amp, making it incompatible. Luckily I had another antenna I was able to use.

Did not work well

Hooked an antenna to my brother's TV. He got only one major channel. Added this product and he no longer got that channel. Reception was better without the Jolt.

easy to set attach to your t.v.

Pros: i am connected to an out side attana, and after the connection to my t.v. i got from 30-55% better reception. i still need something else because my channels still fade out.
