How to Buy a TV Antenna

Posted on 2020-10-19  in Devices

It is one thing to own a TV set, but it is different altogether to receive the channels you want to watch. You need to install a TV antenna to receive the channels available in your area.  Besides, you get to save on paying for Pay-TV stations because you can access so many of over the air free channels with an antenna.

With so many types of antennas in the market, choosing the best one can be difficult. If you want less hassle, you can select an omnidirectional outdoor TV antenna. You can check out John temple article on a review of the top omnidirectional antenna to pick the best one for your needs.

Here are some of the considerations when buying a TV antenna:

Whether Indoor or Outdoor

This is due to the blocking of signals by the buildings’ walls and signal interference by reflections resulting from the building’s objects.

Some things that increase signal interference are fluorescent lights, electrical gadgets, and other things. Conversely, external antennas perform better in picking signals but cost more to install. People in high signal areas can rely on indoor TV antennas, but those in poor signal areas need outdoor antennas.

Whether for Terrestrial or Satellite Broadcasts

Various antennas are applicable for terrestrial transmission, which could be internal or external antenna in several forms. The terrestrial transmissions mostly operate on the UHF portion of the radio spectrum, but some are still running on the VHF spectrum portion in some countries. The vital thing is to have a specific satellite antenna for satellite transmissions and have a terrestrial antenna for terrestrial TV transmissions.

Antenna Type or Style

For satellite transmission, the parabolic reflector style of the antenna is used. Another design is the log periodic antenna used where the TV stations are widely spaced in frequency, requiring a wide bandwidth.

The size and the gain should dictate the choice of the antenna style. Antenna styles that are physically too large may be complex to install and will be susceptible to damage by the wind; hence need more robust installation, which means more costs.
