Prior to the adoption of blogging, you should be on our company’s products have a certain understanding, today, we are going to introduce a new product–Antenna Distribution Systems,which are one of the hottest products.
Mistakes in antenna selection, placement, or cabling can cause short range, dead spots in the performance area or low signal strength at the receiver that leads to frequent dropouts.
Before we cover placement, let’s review the types of antennas you’re likely to encounter in a wireless system.
Omnidirectional Antenna Types
The size of an antenna is directly related to the wavelength of the frequency to be received. The most common types used in wireless audio systems are 1/4-wave and 1/2-wave omni-directional antennas, and unidirectional antennas.
¼-Wave. This antenna is one-quarter the size of the desired frequency’s wavelength. (Example: A 200 MHz wave has a wavelength of about 6′, so a ¼-wave antenna length would need to be approximately 18″.) For VHF Applications, an antenna anywhere from 14–18 inches is perfectly appropriate as a 1/4-wave antenna. Since the UHF band covers a much larger range of frequencies than VHF, 1/4-wave antennas can range anywhere from 3 to 6 inches in length, so using the proper length antenna is important.
½ Wave. This antenna is one-half the size of the desired frequency’s wavelength. (A 1/2-wave receiver antenna would be about 3 feet long for the 200 MHz wavelength in the example above.)
Our antenna distribution systems having a stable signal receiving performance and good sound transmission. Specific performance is as follows:
Antenna Distribute Implement
>Low noise and amplifying circuit design
>8-channel low loss antenna dividers circuit design,four Single-channel automatic selective receiver can be used in a couple antennas.
>BNC pin ensure the reliable connection.
Wide Band Directional Antenna
>Directional antenna,decrease the interference to other closed equipment.
>High sensitivity,increase the signal receiving range.
>Wide frequency range,cover all of the UHF wireless frequency point.
