Mohu Leaf

I use the Mohu Leaf OTA antenna and I purchased the Jolt Amplifier to stop interference from my neighbor's truck. It doesn't show how to install it when using a Tivo dvr. I emailed their Customer Support and they told me I need a bigger antenna. I only need instructions on how to set it up using the Tivo Roamio. Can someone please help me with this?
Thanks, Marge
