Choosing the Best Outdoor Antenna for Free TV: Guidelines and Considerations
Free over-the-air (OTA) TV has become a popular choice for viewers seeking a cost-effective alternative to cable or satellite services. To make the most of this option, choosing the right outdoor antenna is crucial. But what makes an "best" outdoor antenna? The answer largely depends on your specific location, the quality of your local broadcast environment, and the availability of TV stations in your area. This article provides detailed insights into how to choose the best outdoor antenna for free TV based on your needs.The Importance of Your Location
Location is a critical factor in determining the best outdoor antenna for you. How far you are from TV stations and the presence or absence of obstacles can significantly affect how well your antenna performs. For instance, if you live in a place with a quiet radio frequency (RF) environment and are close to several TV stations, a low-gain antenna with vertically stacked elements might be the best choice.For example, in my area, which is about 30 miles away from several stations, I have found that a low-gain UHF antenna with four vertically stacked 'bow tie' elements works best. Such an antenna can pick up the stations I want to watch without the need for a rotator. Since there are no active VHF stations, a UHF-only antenna is sufficient. The low gain ensures a clear signal even at this distance.
High Gain vs. Low Gain Antennas
The choice between a high-gain and low-gain antenna also depends on your specific situation. If you are far from any TV stations, a high-gain antenna with a very narrow horizontal aperture could be necessary. These antennas need to be pointed directly at the station, making rotation necessary when changing channels. However, if you are closer to your stations, a low-gain antenna can provide sufficient signal quality without the need for constant adjustment.For instance, if you live out on the prairie and are 150 miles from a major city, a high-gain antenna would be ideal for picking up the signals from that city. However, if most of these stations are essentially in the same direction, a single high-gain antenna can suffice.
Facing RF Noise and Considerations
Another important consideration is the amount of RF noise in your location. In areas with a lot of RF noise, such as near industrial areas or densely populated areas with many sources of electronic interference, it is beneficial to use a mast-mounted amplifier. This amplifier reduces the noise picked up by the transmission line between the antenna and the receiver, providing cleaner signals.For example, someone living in an apartment complex with numerous computers and other electronic devices might benefit greatly from an amplifier at the antenna. However, in my case, the signals are strong and local noise is minimal, so an amplifier doesn't make much difference.
Installation and Considerations
Finally, the location where you can install the antenna is also critical. If you can install it on your roof, you are likely to get better reception than an indoor antenna. Installers often recommend outdoor antennas for obtaining a wide coverage of channels. However, if you live in a smaller space, such as an apartment, an indoor antenna might be your best option.For instance, I have a 8-bay flat antenna on my roof, and it gives me 60 channels from 40 miles north of Detroit. If I were in an apartment, I would likely receive nearly zero channels without an outdoor antenna.
