UHF Terrestrial Wave Digital TV Antenna Indoor And Outdoor DTMB HD Signal Receiver

There are several different types of antennas for you to choose from. They are indoor antennas, outdoor antennas and array antennas used in remote areas. You need to choose according to your own needs.

The indoor antenna has two freely adjustable telescopic rods. They are optimized for receiving VHF signals. Although indoor antennas are better than none, they are not the best choice for receiving TV signals.

Outdoor antenna is the most common antenna, they can provide a good signal. You can often see outdoor antennas on the roof or on the mast. Outdoor antennas are usually composed of several basic antennas arranged from short to long. This structure can concentrate the signal and effectively reduce the multi-channel propagation, you can think of it as a magnifying glass for electronic signals. Outdoor antennas can come in a variety of sizes.

If you live in a remote area, a large antenna is your best choice. For example, if you live in a valley, a mountain or a large obstacle, you need a large antenna to get the maximum range of signal, but don't buy an antenna beyond your normal needs. Those giant TV antennas are only available in remote areas. If you live in an ordinary area, large antennas may receive too many signals, resulting in distortion or channel interference, as well as crosstalk due to receiving weak signals in the distance, resulting in signal overlap.

Electrical Characteristics:

Use a revolving stand. If one channel is to the north of your location and the other is to the west of your location, you may need to use an antenna turret to turn the mast toward the tower.
If the angle of each channel is not different, or if the TV station is near your location, then you don't have to worry about the revolving frame. But if the angle between different TV stations is 30 degrees, depending on the distance between the signal transmitting tower, you may need to rotate the stand. If you don't have a revolving stand and have to climb up to the roof to adjust the antenna every time you change the channel, you'd better buy a revolving stand as soon as possible!
