Product Description

Product Description

GL0809D-15 – High-Gain 15 dBi 915MHz Directional Panel Antenna

The GL0809D-15 is a high-performance directional panel antenna designed for the 915MHz ISM band (902-915MHz), delivering a high gain of 15 dBi with VSWR ≤1.8 for extended and focused coverage. It features right-hand circular polarization (RHCP), a 30° horizontal and 28° vertical beamwidth, a front-to-back ratio ≥25 dB, port isolation ≥28 dB, 50Ω impedance, and supports up to 50W input power with DC ground lightning protection. Housed in a durable ABS radome measuring 305×305mm and equipped with an SMA male connector and RG58 cable, it operates reliably from -40°C to +65°C. Ideal for long-range point-to-point links, wireless backhaul, remote monitoring systems, and outdoor-industrial networks requiring stable, high-gain directional performance in the 915MHz band.

FAQ

Q1: What is an ISM band antenna?
A: An ISM band antenna is designed to operate in the Industrial, Scientific, and Medical frequency bands, which are license-free and widely used for wireless communication technologies such as WiFi, Bluetooth, Zigbee, LoRa, and other IoT devices.

Q2: Are LoRa antennas and general ISM antennas interchangeable?
A: They can be used interchangeably if the frequency range matches. However, LoRa antennas are often tuned for specific LoRa frequency bands and may offer better performance in LoRa-specific applications compared to a general-purpose ISM antenna.

Q3: What frequency bands do LoRa antennas support?
A: Common LoRa frequency bands include 868 MHz (EU), 915 MHz (US), 433 MHz (Asia), and 490 MHz (Japan). It is important to select an antenna that matches the regional frequency plan of your LoRa network.

Q4: What type of connector is commonly used for LoRa and ISM antennas?
A: SMA and RP-SMA connectors are widely used, especially for gateway and device antennas. N-type connectors may also be found in higher-power or outdoor applications.

Q5: What regulations apply to LoRa and ISM antenna use?
A: ISM band usage is subject to regional regulations regarding frequency, transmit power, and duty cycle. Always comply with local radio communication laws when deploying LoRa or other ISM band devices.
