[Introduction]：TX433-BLG-20L is a 433MHz band fiberglass antenna with an antenna length of about 200mm and an N male elbow interface. The antenna shell is made of glass fiber material and contains multiple sets of antenna elements, which has the advantages of high gain and long communication distance. The antenna is waterproof, sunproof, windproof and has strong sealing properties, and can be widely used in harsh environments such as the wild. Due to the high stability and reliability of fiberglass antennas, it can also be used in places with high requirements such as wireless terminal equipment, base stations, gateways, wireless modules, APs, routers, and wireless data transmission stations.
