Which external antenna is best for you?

　　Main types of external antennas

　　External antennas are mainly divided into two categories: 4G omnidirectional antennas and directional antennas, with impedances of 50 ohms and 75 ohms respectively. For example, our best-selling home devices are equipped with Yagi antennas (a type of directional antenna), while popular business packages offer two options: Yagi antennas and omnidirectional antennas to meet the needs of different scenarios.

　　When choosing an antenna, it is key to understand the core differences between the two categories, which are explained in detail below.

　　Commonalities of the two types of antennas

　　Both 4G omnidirectional antennas and directional antennas (unidirectional antennas) can receive existing cellular signals (including 5G, 5G LTE, 4G LTE, 3G), and will enhance the signal strength after receiving the signal, but the enhancement will vary depending on the signal type.

　　Differences and characteristics of the two types of antennas

　　Omnidirectional antenna

　　Working principle: Omnidirectional antennas can achieve 360-degree all-round signal reception, do not have signal filtering function, and will capture all existing signals within the range. If there are multiple cellular base stations near you, this feature allows you to easily switch between different operators, which is very flexible to use. The appearance of 4G omnidirectional antennas is mostly bar-shaped, similar to the radio antenna on the car, and has a high degree of recognition.

　　Applicable scenarios and advantages and disadvantages:

　　Biggest advantage: easy installation

　　Just install it in a location with a strong signal to receive signals 360 degrees without dead angles. The operation is simple and no complicated wiring is required.

　　Pros:

　　The installation process is simple and can be completed without professional skills.

　　It can enhance all mobile phone signals in the area and cover signals of base stations of different operators and different locations.

　　When the main reason for poor indoor signals is building barriers (such as walls, metal structures, etc.), the enhancement effect on 5G, 4G LTE, and 3G signals is significant.

　　Disadvantages (Cons):

　　The coverage range is not as wide as that of directional antennas.

　　The signal enhancement amplitude (gain) is lower than that of directional antennas.

　　It is susceptible to "signal interference" and may cause the effect to decrease due to signal overload in busy urban areas with dense signals.

　　Not suitable for remote areas such as rural areas - the core problem of such areas is that they are too far away from signal towers, and omnidirectional antennas are not optimized for this.

　　Summary: With its simple installation, 4G omnidirectional antennas have become a common choice for most users, suitable for situations with basic signal enhancement needs and uncomplicated scenarios.
