Take advantage of free HDTV signals with the Vortex HD antenna made by Sewell which can pick up over-the-air HD signals from up to 125 miles (depending on obstructions and the topography of your area).
Vortex HD

Compatible with all TVs and HD signals

Whether you live in a big city or out in a rural area, chances are you have free available HD signals being broadcast in your area. All you have to do is get this antenna installed and you'll be enjoying crystal clear HDTV in your home.

This antenna is also perfect for standard televisions that don't support HD. You of course need an HDTV to enjoy full high definition images, but there are also many standard definition signals available and the Vortex will pick all of them up.

Motorized Rotation and Remote Included

The Vortex HD includes a built-in motor and wireless remote. This means you need only to get on the roof once. Once installed, if you ever need to make an adjustment, the wireless remote allows you to rotate the antenna 360 degrees. The rotator allows one full rotation and then automatically rotates the opposite direction for another full rotation to avoid cable wrapping around the pole.

Built-in Booster

There are other antennas on the market that claim to have a built-in booster but don't go to any lengths to explain what that means. With antennas, since they passively receive signals that are broadcast from afar, have no way of 'boosting' the signal coming from the signal tower. The signal any antenna receives is as good a signal that it's ever going to get, no matter how expensive it is.

The Vortex HD, however, does have a booster that strengthens the signal strength in the wire between the antenna and your TV. This allows you to increase the length of your cable without worrying about signal loss. With a high-quality coaxial cable, you could extend the signal up to 300 feet.

Easy Assembly

The majority of the parts are already assembled. The estimated time to get the antenna ready for mounting is 5-7 minutes out of the box.

I have two HD TV's, what type of splitter do I need to connect both TV's? Thank you, Mo


The splitter is built in to this antenna. There are two Coax output ports on the base unit and you will connect one to one TV and the other port to the second TV.

If I mount the antenna on my roof, can I put a power supply in the house between the antenna and the TV?


This antenna actually comes with a power supply that you do place inside the house between the Antenna and the TV.

Can I mount this where my old Direct TV dish is and use the same, already ran, coaxial cord that goes into my walls?


Yes that should work fine.
