Installing an outdoor TV antenna yourself can be a big challenge. This job takes patience, time and expertise. There are plenty of safety precautions to keep in mind. Knowing what you're doing before you take a single step onto the roof will help you get the job done quickly and correctly--without the expensive help from an electrician. Follow these steps to learn how to install an outdoor antenna for your TV.

Buy an outdoor antenna. Make sure you get a complete mounting kit as well as any other accessories you might need to mount this antenna on your type of roof.

Choose the mounting site for your outdoor antenna. This is usually at the peak of the roof. The higher up that you have your antenna, the better chance you have of avoiding any interference from other buildings and trees.

Take safety precautions when getting onto the roof. Use a ladder that extends well past the roof line and wear shoes that will give your feet a good grip on an angled surface. Take extra care when placing your steps to anticipate stepping on a loose shingle.

Take your tools and antenna up to the roof. Double check that you have everything that you'll need, like drills, wrenches and pliers, to cut down on extra trips.

Secure the antenna mounting kit to the spot you decided was best for reception. Make sure that the wooden decking under the shingles is solid and not soft from exposure so that your mounting bolts will have a solid surface to grip.

Check that the mount is secure. Then, attach the antenna according to the included instructions. You may want to use an antenna rotator so that the antenna can swivel around with ease. This gives you the option to adjust the reception more easily.

Run the necessary cables from the antenna into the home. Depending on the model, you may be able to use the cables from your old antenna. If you prefer, you can route the new cable following the same path as the old cable to keep from drilling more holes into your house.

Secure the cables tightly with cable ties and weatherproof tape to the roof and down the side of your home. It will take a bit more time; but for a better-looking installation, route the cable along the soffit where it joins the siding to hide it.

After the installation is complete, adjust the antenna until you've reached your desired level of reception. Once you've found the perfect setting, snug the bolts so that it will not lose its positioning in high winds.


This project can take some time and energy. Don't be discouraged when you have to make minor adjustments. Have a friend or family member there to help you, as it will be a lot easier when trying to run the cables into the house. They can also help you while you adjust the reception on the roof as they view the TV.


This project can be dangerous. There are injuries and even deaths reported every year from homeowners climbing onto their roofs. If, for any reason, you don't feel confident about doing this yourself, you can look up a certified installation expert in the local yellow pages. Always take extra care when working on a roof. Only work in ideal weather conditions. Avoid working on days with high wind, rain, lighting, snow and ice.
