[Introduction]：The TX433-BLG-90P is a 433MHz band fiberglass antenna, approximately 900mm in size, with an N-K connector (N female). The antenna shell is made of fiberglass material and contains multiple antenna elements, offering advantages such as high gain, long communication range, waterproof, sunproof, windproof, and strong sealing. It can be widely used in harsh environments such as outdoor settings. Due to its high stability, reliability, and wide frequency band, this fiberglass antenna is suitable for applications requiring high performance, such as LoRa modules, wireless terminal equipment, base stations, gateways, wireless modules, access points (APs), and wireless data transmission radios.
