Types of Outdoor Antennas

There are a few different types of outdoor antennas that are commonly used to receive local TV signals. The main types include:

- Roof-mounted antennas: These are antennas that are installed on the roof of a house. They provide the best reception as they have a clear line of sight to broadcast towers. Common types include Yagi antennas and multi-directional bowtie antennas.

- Mast-mounted antennas: Similar to roof-mounted antennas are type of Outdoor Antenna but are attached to a freestanding pole instead of being directly mounted on the roof. This allows for better maneuverability to point the antenna in the desired direction.

- Attic/outside wall-mounted antennas: Mounted either in the attic space facing outside through a wall or mounted directly on an outside wall. They don't provide as strong of a signal as roof-mounted but can work well in some cases.

Choosing the Right Type and Size

There are a few key factors to consider when choosing the type and size of outdoor antenna:

- Distance from local broadcast towers - The farther away, the larger antenna needed to pick up signals clearly. TVFool.com can estimate distances.

- Terrain and obstructions - Hills, trees or buildings between the antenna and towers can weaken signals. Consider obstructions when choosing antenna type and height.

- Number of HD channels needed - More channels often require a larger antenna. Multi-directional types are better for lots of channels from different directions.

- Installation location options - Roof mounting provides best reception usually but mast, attic or wall mounting considered if roof isn't an option.

Proper Installation and Maintenance

Even with the right equipment, an outdoor antenna needs proper installation to perform as it should:

- Location is important for reception. Elevated areas like the roof are best. Orient antenna towards nearest towers.

- Use quality coaxial cable and connectors. RG-6 cable is commonly used, keep runs under 75 feet for best signal strength.

- Secure antenna mount and pole sturdily using corrosion-resistant hardware. Wind conditions can cause issues if not firmly secured.

- Periodically check cables/connections for damage from weather/wildlife which can degrade reception overtime if not addressed.

- Consider additional surge protection on cable line entering home if antenna mounted far from grounding point to minimize risk of lightning strikes.
