The different properties of the resin give different corrosion resistance to FRP, enabling it to be used for a long time under the corrosive environment of gas and liquid media with different acids, alkalis, salts and organic solvents.

Coaxial cable, also known as coaxial, is used to transmit radio frequency (RF) signals. It has low emission losses and provides protection against electromagnetic interference so that the low power consumption of the signal will be transferred over lon

The operating frequency range of a walkie-talkie is usually very low, ranging from several tens of megahertz to several hundred megahertz. This is because most intercom systems do not have repeater stations (or base stations) for low-cost and convenient d

The wireless APs built-in antenna usually uses MIMO technology. MIMO is only available after the 802.11n protocol. Previously, 802.11a, b, and g did not. Nowadays, wireless AP products basically all support 802.11n protocols, which means that most of the

The wireless signal received by the wireless terminal is transmitted through a built-in or external antenna in the wireless AP. Looking at the wireless AP in the market, you will find there is an important parameter indicator, that is, the antenna gain
