What is Outdoor Panel Directional Antenna
Mar , 05 2022
Panel antenna belongs to directional antenna, Panel antenna is a kind of mobile communication system antenna, mainly used for outdoor signal coverage. Whether IT is GSM or CDMA, Panel antenna is the most widely used type of extremely important base station antenna. The advantages of this antenna are: high gain, good sector pattern, small back lobe, convenient vertical plane d...

The operating frequency range (bandwidth) of the antenna
Mar , 12 2022
Whether it is a transmitting antenna or a receiving antenna, they always work within a certain frequency range (frequency bandwidth). There are two different definitions for the frequency bandwidth of an antenna—— 1. The working frequency bandwidth of the antenna under the condition that the SWR ≤ 1.5; 2.The b...

Television Antennas
May , 30 2022
Television antennas are devices that allow you to catch waves at television frequencies and watch television programs. They need to be strong enough to catch up and amplify any kind of television signals, in order for you to get a good reception and be able to connect and watch a number of channels at the same time. So, a television antenna is used to amplify television signal, and it can also hav...

What is the difference between band-reject filter and bandpass filter?
Jul , 01 2022
A bandpass filter is an electronic device or circuit that allows signals between two specific frequencies to pass, but that discriminates against signals at other frequencies.In signal processing, a band-reject filter (also called a band-stop or notch filter) is a filter that passes most frequencies unaltered, but attenuates those in a specific range to very low levels. The main difference between...

What's low PIM?what's the Importance of Low-PIM?
Aug , 06 2022
Low PIM means stronger signal,which means higher revenue for happy customers and operators. From a hardware perspective, this means that every connection must be designed to minimize PIM and tested to ensure proper installation. In order to understand the importance of low PIM antennas, Low PIM Combiner and Low PIM Splitter/Coupler in 5G networks, it is critical to understand what PIM refers to. P...

radio frequency combiner
Sep , 12 2022
The circuit breaker is generally used at the transmitter. It combines two or more radio signals sent from different transmitters into an RF device transmitted by the antenna. At the same time, the interaction between signals at different ports is avoided. A circuit breaker typically has two or more input ports and only one output port.Port isolation is an important indicator that describes the cap...

DAS & Small Cells: What’s The Difference?
Oct , 28 2022
The radio heads of a distributed antenna system are essentially “dummy” radio heads: these access points don’t provide any signal processing like a small cell antenna system would. Instead, DAS radio heads relay the signal to a cellular base station located at a central hub. Once the signal is relayed to the hub, it’s processed at that central location. Base stations installed at a central hub are...
