Сведения о товаре

Характеристики продукта

A compact, high-gain directional antenna designed based on Yagi-Uda principles, adopting a unique fishbone-style array with densely spaced directors. It is constructed with a lightweight aluminum or FRP main beam, folded dipole and reflector. Optimized director spacing enables precise signal focusing. The antenna covers the frequency range of 300–3000 MHz, features an IP65 weatherproof rating and withstands wind speeds up to 60 m/s.

Key features: High gain (>18 dBi), excellent interference rejection, compatible with pole and wall mounting.

Limitations: Narrow bandwidth; precise alignment is required.

It is offered in cost-effective consumer-grade and heavy-duty professional versions. OEM customization is available for frequency, polarization, SMA or N-type connectors.

Часто задаваемые вопросы

Q1: How does this fishbone design manage such a wide frequency range (300-3000MHz) compared to a traditional narrow-band Yagi?: A1: Traditional Yagi antennas are highly resonant and limited to narrow bandwidths. This fishbone configuration utilizes optimized director spacing and a tapered element arrangement similar to log-periodic principles, enabling a remarkably broad frequency response across the 300-3000MHz spectrum while suppressing unwanted impedance mismatches.
Q2: The specification sheet lists a 5-8dBi gain, but the text mentions high-gain Yagi principles. How should an engineer interpret this?: A2: When an antenna is engineered to cover an ultra-wideband spectrum (up to 3GHz), RF energy is distributed across a broader footprint. This results in a stable, consistent directional gain of 5-8dBi paired with a wide beamwidth (110° H / 95° V), which offers excellent sector coverage. For specialized, narrow-band OEM requirements, the element configuration can be adjusted to maximize peak gain.
Q3: What are the primary structural differences between the consumer-grade and rugged professional versions?: A3: The consumer-grade version focuses on cost-efficiency for indoor or shielded deployments. The professional version is built using heavy-duty aluminum or a fiber-reinforced plastic (FRP) radome to withstand harsh outdoor marine or industrial environments, guaranteeing long-term mechanical survival against high wind loads up to 60m/s.
Q4: Can this antenna handle high-power industrial RF transmitters or cellular base station equipment?: A4: Yes, the antenna is fully rated for high-power B2B industrial transmission systems, supporting a maximum input power of up to 200W. It features a ruggedized folded dipole feed mechanism and can be ordered with professional-grade, low-loss N-type or SMA female RF connectors to match your existing feeder cable infrastructure.
Q5: What are the installation best practices for deploying this antenna on outdoor towers or walls?: A5: The antenna supports both pole and wall mounting configurations. Due to its directional nature, the main boom must be aligned toward the target sector or signal source. For optimal performance, ensure the polarization (vertical or horizontal) matches the transmitting system, and ensure the RF connector interfaces are properly weatherproofed with coaxial sealing tape to preserve the IP65 rating under extreme temperatures (-40°C to 60°C).
