Installing an outdoor antenna can help improve your television, radio, or wireless internet reception. With the right antenna properly mounted and aimed, you can access more channels and get clearer signal quality. This guide will provide a step-by-step walkthrough on selecting, installing, and optimizing an outdoor antenna.
Choosing the Right Outdoor Antenna
When selecting an outdoor antenna, there are a few key factors to consider:
Type of Signal
What type of signal are you trying to improve – television, FM/AM radio, wireless internet? Different antenna types are designed for different signals:
- Television – A directional Yagi or multi-directional outdoor HDTV antenna works well. Ensure it covers the bands for the channels you want to receive such as UHF, VHF or both.
- FM/AM radio – Use an omnidirectional FM or AM dipole antenna or loop antenna for radio.
- Wireless internet – A directional parabolic antenna is best for long-range WiFi. Omni or panel antennas can also work for shorter distances.
Distance and Obstructions
Consider how far you are from the signal source and what obstructions are between you and the transmitter such as hills, buildings, trees. The further away, the larger more directional antenna you may need. Omni antennas work better for shorter distances and if the signal is coming from multiple directions.
Outdoor Mounting Location
Choose a location that has a clear line of sight to the signal transmitter. The highest elevation possible is best to get above obstructions. Chimneys, rooftops, poles etc. are good choices. Ensure it is a location you can safely install on and run coaxial cable to.
Frequency Range
Ensure the antenna is designed for the frequencies used in your area for the signal you want to receive. For example HDTV broadcasts are mainly UHF and VHF frequencies.
Gain
Higher gain antennas can capture weaker signals from farther away. But also focus the signal in specific directions. Lower gain omni antennas receive from multiple directions. Find the right balance of gain needed for your situation.
Rated Wind Load
For roof and elevated installations, ensure the antenna can withstand the wind speeds in your area to avoid damage.
Cabling
Use high-quality, weatherproof coaxial cable designed specifically for antenna use. The cable length will affect signal quality. Minimize it where possible.
Consider these factors when shopping for the right outdoor TV or radio antenna to match your specific needs and situation. Consulting with a knowledgeable antenna installer can help make the best choice.
Installation Tools and Materials
Installing an outdoor antenna requires some basic tools and materials:
- Antenna mast or mounting pole
- Antenna mounting bracket or clamps
- Coaxial antenna cable
- Ground block/lightning arrestor
- Cable ties
- Coaxial wall entry plate
- Silicone sealant
- Tools:
- Drill
- Screwdrivers
- Wrenches
- Cable stripper
- Crimping tool
- Voltmeter/multimeter
Ensure you have all equipment needed for proper installation before beginning. Having a helper makes the process easier and safer when working at heights.
Use quality materials designed for antenna use. Follow all safety procedures when working on roofs or ladders.
Selecting the Install Location
Choosing the optimal outdoor location for mounting the antenna is key to maximizing your reception.
Consider these factors when surveying potential install spots:
- Height – The higher, the better to get clear line of sight over obstructions.
- Clear signal path – Try to aim the antenna with as few obstacles like trees or buildings in the path to the transmitter.
- Structural integrity – Choose a solid mounting surface like a chimney, fascia board or pole that can safely support the antenna and mast.
- Cable access – There should be a viable route to run the coaxial cable into the house to the TV, radio or wireless router.
- Grounding – Pick a spot with proper grounding potential for electrical safety.
- Aesthetics – Try to select a low profile location if possible to minimize visibility.
The roof or chimney often provides good height to achieve an unobstructed signal path. Consult your antenna specs to determine how much clearance is needed around the antenna. Do a site survey and consider a few option before settling on the optimal antenna location.
Mounting the Antenna
With the location chosen, securely mounting the outdoor antenna is the next step. Follow these best practices:
Attach Mounting Bracket
Attach the mounting bracket designed for the antenna to the surface (chimney, pole, fascia) in the desired location using appropriate screws or clamps. Ensure it is anchored firmly into structural framing members and can support the weight and wind load.
Position Antenna
Attach the antenna to the mounting bracket with the proper bolts or U-clamps according to the manufacturer instructions. Ensure connections are tight.
Consider Aiming
For directional antennas, adjust the orientation to aim towards the signal source transmitter. Use a compass to verify aim.
Secure Mast
Use appropriate poles in the needed length and install securely into the mounting bracket. Lock all joints and connections tight. Use guy wires if needed for additional support.
Prevent Movement
With the antenna and mast fully assembled and tightened, check that there is no excessive movement or vibration that could loosen connections over time.
Proper mounting is essential to keeping the antenna pointed correctly and secured safely. Have an assistant help with lifting and adjustments during installation.
Running & Connecting the Antenna Cable
With the antenna aimed and mounted, the next stage is connecting it to your TV or radio located indoors:
Select Cabling
Choose quality RG6 rated coaxial cable designed specifically for antenna use. The cable length affects signal, so run the shortest route possible from antenna to TV.
Outdoors Cable Route
Map out how the cable will run from antenna into the house. Look for the most direct path minimizing bends and tension. Use cable staples to securely attach to surfaces. Seal any exterior wall holes.
Ground Block
Install a ground block or lightning arrestor near the antenna to protect from electrical surges coming down the line. Ground appropriately.
Indoor Entry Point
Drill a hole through the wall or window frame for cable entry using a cable entry plate. Seal any gaps with silicone. Avoid running near power lines.
Connect Antenna
Attach the cable connector securely to the antenna output terminal by hand tightening. Do not use tools to avoid over tightening.
Indoor Routing
Run cable neatly along baseboards and ceilings inside to the location of your TV or radio. Use cable clips. Keep cable away from electrical lines.
Antenna Signal Splitter
To connect one antenna to multiple devices, install a splitter near the entry point. Ensure the splitter is rated for the appropriate frequency range.
With good quality cabling and protected entry points, the signal from the outdoor antenna can now be reliably transmitted to where it’s needed indoors.
Optimizing the Antenna Signal
To get the best reception from your new outdoor antenna, there are some optimizations you can complete:
Fine Tune Aiming
For directional antennas, carefully adjust the horizontal and vertical aim while monitoring the signal meter on your TV. Rotate in small increments to pinpoint the strongest signal angle.
Adjust Antenna Height
Try raising or lowering the antenna within the available adjustment range on the mount. Even small height increases can improve reception.
Check Connections
Inspect all ports and connections to ensure they are tight and not corroded. Replace any suspect connections. Use coaxial sealant if needed.
