EBYTE TX470-BLG-12 Antenna Specification Sheet
Product Overview
The TX470-BLG-12 is a fiberglass antenna operating in the 470MHz frequency band. It features a length of approximately 120mm and an N-J connector (N Male). The antenna's housing is made of fiberglass material, containing multiple antenna elements that provide high gain and long communication distances. This antenna is waterproof, sun-proof, wind-proof, and offers strong sealing, making it widely applicable in harsh outdoor environments. Its high stability and reliability also make it suitable for demanding applications such as wireless terminal equipment, base stations, gateways, wireless modules, Access Points (APs), routers, and wireless data transmission stations.

Test Parameters
Voltage Standing Wave Ratio (VSWR) Graph: The graph illustrates the antenna's performance across the frequency range. At 460MHz, VSWR is 1.8325; at 470MHz, it is 1.9647; and at 480MHz, it is 2.2882. The graph indicates that the VSWR remains below 2.0 within the specified operating band, signifying good impedance matching.
Smith Chart: The Smith chart displays impedance characteristics. Data points at 460MHz, 470MHz, and 480MHz are plotted, showing complex impedance values. For example, at 470MHz, the impedance is approximately 42.74 + j30.94 Ohms (with a capacitive reactance of 10.946 pF).
Frequently Asked Questions (FAQ)
- Antenna frequency must match the wireless device frequency for optimal communication; otherwise, performance will be poor.
- Lower communication frequencies result in longer wavelengths, which improve diffraction performance.
- Direct line-of-sight obstructions will cause signal attenuation and reduce communication range.
- Ensure correct antenna orientation; incorrect installation can lead to reduced transmission distance.
- Ground absorption of radio waves can affect performance; testing near the ground may yield poorer results. Elevating the antenna is recommended.
- Seawater strongly absorbs radio waves, making testing near the sea less effective.
- Proximity to metal objects or placement within a metal casing will cause significant signal attenuation.
- Poor impedance matching between the antenna and communication equipment will result in degraded communication performance.
