The difference in the number of router antennas? For a single-band router, the number of 2.4G/ 5.8G Router Antenna corresponds to a different number of radio frequency parts, which is related to the radiation area and bandwidth allocation. The penetration power and Transmission rate of the wireless transmission of the dual-band 2.4G+5.8G frequency bands are different. For dual-band routers, the 5G Router for each band need to be separated. The number of Router Antenna Extender for single-band can be odd or even, but the number of Rubber Router Antenna for dual-band must be even. For the four Router Antenna commonly used in ordinary homes, the increase in the number of antennas increases the number of radio frequency transmitting parts, which increases the speed of data transmission and radiation range for connected devices. However, there are many routers on the market that do not have so many radio frequency parts, and the antennas are only furnishings. Therefore, when choosing a wireless router, it is not that the number of antennas is better, but the selection needs to be comprehensively considered according to the actual use environment.
