How to Boost an Outdoor TV Antenna Signal

Outdoor TV antennas provide access to free over-the-air broadcasts from major networks. However, factors like distance from broadcast towers, terrain, buildings, foliage, and weather can impact signal quality and channel availability. Fortunately, there are several methods to help improve reception.

Check Antenna Direction

The first step is ensuring your antenna is aimed correctly towards the nearest TV broadcast towers. Most outdoor antennas are directional, meaning optimal reception comes from pointing them in the direction of the signal source.

You can use AntennaWeb to identify exactly where local towers are located based on your address. Make sure your antenna is facing this direction as precisely as possible. Even slight adjustments can make a big difference.

If you notice neighbors’ antennas all seem to point the same way, align yours in that direction as well.

Find Your Exact Broadcast Location

For more precise antenna aiming, use the FCC’s DTV Reception Maps. Enter your address to see a Google Map with your exact broadcast towers highlighted.

Point your antenna towards the closest markers, adjusting left or right as needed. Pay attention to the compass direction specified.

Check Signal Strength

Most TVs have a built-in signal meter you can access through settings. As you adjust your antenna, check for improvements in signal quality. Try to maximize signal strength across desired channels.

Aim for at least 60-70% signal to avoid issues, though a perfect 100% is ideal.

Improve Line of Sight

A clear line of sight between your antenna and the broadcast tower is crucial for the best reception. Identify and remove any obstructions between the two if possible:

  • Trees/Branches – Trim back branches or foliage blocking the signal path.
  • Buildings – Relocate the antenna above or away from structures if feasible.
  • Terrain – Adjust antenna height to clear hills or terrain variations.

In some cases, elevating the antenna higher or using a mount that overhangs rooftop edges can significantly improve line of sight.

Upgrade Coaxial Cables

Signal quality degrades over longer cable runs from the antenna to your TV or receiver. If using a very long stretch of cable, upgrade to a thicker, higher-quality RG6 model designed specifically for TV connections.

RG59 cable tends to work for shorter runs under 50 feet. Over that, RG6 is better equipped to handle the higher frequencies used for HDTV while minimizing signal loss.

Add a Preamplifier

Installing an antenna preamplifier near the antenna can boost weak signals to maintain quality over long cable runs. Place it before any splitters or distribution amplifiers.

This strengthens the signal at the source rather than amplifying an already degraded signal. Just take care not to overload your TV’s tuner on very strong signals.

Use an Antenna Rotator

If broadcast towers are located in different directions from your home, consider installing an antenna rotator. This allows rotating the antenna to alternate between towers for multi-directional reception.

Aim the antenna as needed to tune different channels rather than relying on a fixed position. Quality rotators start around $$100-150$$ but ensure flexibility.

Combine Antennas

For the best reception across a wide range of channels and directions, try mounting multiple antennas. Feed their signals into a distribution amplifier that combines them into a single line.

Aim each antenna at separate broadcast towers in your area. This merges all received channels allowing you to tune them from one connection.

Call an Installer

If you’ve tried these tips without noticing significant improvements, your situation may need professional assistance. TV antenna installers can:

  • Strategically place antennas while checking signal strength.
  • Identify ideal mounting locations tailored to your location.
  • Properly configure amplification and distribute signals across your home.

Though hiring an installer costs over just purchasing equipment, their specialized knowledge helps ensure optimal signal quality.


Boosting antenna reception typically requires carefully positioning and adjusting your setup. Checking for obstacles, upgrading cables, adding amplifiers, utilizing rotators, or combining antennas can all assist with improving signal strength. Just be sure to confirm antennas directly face your closest broadcast tower location.

With a properly tuned installation, even homes far from stations can receive crisp, clear over-the-air broadcasts. But if issues persist despite troubleshooting, don’t hesitate to call an expert antenna installer. Their assistance can take your setup to the next level when DIY efforts alone aren’t enough.

The key is tailoring adjustments and accessories to strengthen signal quality by compensating for environmental factors. Experiment with different techniques to determine an optimal approach for your location. Achieving a reliable antenna configuration ensures access to free TV unencumbered by weather disruptions or intermittent reception.
