Effect Of Antenna Distribution Layout

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.

How To Pick Powerful Wireless Microphone Equipment

Are you looking for Channel Wireless Microphone Systems online?  Our company-Enping Raxikol Electronic Manufacture Factory will be your best choice,we can supply high quality and special wireless microphone system for you.

The UHF PLL Dual Channel Wireless Microphone System is specifically designed for multi-system of KTV and campus.The system adopts same-band design and the two transmitters working can be easy used interchangeably. The system includes Dual Channel Receiver, Handheld Transmitter and Bodypack Transmitter.

The main features of a wireless microphone system

A wireless system contains just two parts:

Transmitter – connects to the microphone and transmits the signal wirelessly

Receiver – connects to the mixer or recorder and receives the wireless signal transmitted

Sometimes the transmitter and receiver is the same instrument, and is called a tranceiver. You still need two of them, though.

When choosing wireless systems, here are the important ‘technical’ considerations (in addition to audio quality) one must keep in mind:

Transmitting power, measured in mW or milli Watts (sometimes written as ‘mw’) – this decides how much range/distance it can transmit over. Usually 10-125 mW.

Frequency band/group – it is expensive to have one system efficiently transmit all frequencies of the spectrum. Moreover, if a certain range is illegal, it is pointless to waste resources on it. For this reason, you’ll find systems divided into different ‘frequency blocks’. Choose the one important to you.

Resistance to interference – needs to be tested in the real world, every other way is too complicated and unnecessary. Low frequencies are better generally because they ‘bend around’ walls better. If you’re in an area with a lot of ‘chatter’ things will quickly get complicated.

Reliability – how strong is the signal from end to end? The number and type of antennas tells us how reliable it is. More than one is always good.
