• Scale Indication: 10° ~ 90° (wider scale range for more precise pointing)

Q: How much larger is the 90cm antenna compared to the 60cm/75cm antennas?

A: The 90cm antenna has a major axis of 900mm and minor axis of 990mm. Effective area increases by approximately 125% compared to the 60cm antenna and approximately 44% compared to the 75cm antenna. This means significantly higher gain and stronger weak signal reception capability.

Q: What does 40.32dBi gain mean in practice?

A: Gain is a core performance indicator of an antenna. 40.32dBi is an excellent level for a 90cm Ku-band antenna, meaning the antenna can highly concentrate signal energy for stable reception even in weak signal environments – ensuring clear picture quality.

Q: Is this antenna suitable for balcony installation?

A: Yes. Despite its larger aperture, the 90cm antenna's compact design with L-wall mount still allows installation on balcony walls or railings. We recommend confirming sufficient installation space before proceeding.

Q: Does installation require professional expertise?

A: No. The product features an optimized structural design for rapid assembly. Both elevation and azimuth have clear scale indications (10~90°, wider range). Regular users can complete installation and pointing by following the manual.

Q: What are the advantages of fully galvanized steel construction?

A: Fully galvanized steel offers excellent corrosion resistance. Combined with professional coating treatment and passed Neutral Salt Spray, Damp Heat, UV, and Accelerated Aging testing, it is especially suitable for long-term outdoor use in coastal high-salt environments.

Q: Operating temperature -50℃~+70℃ – does it also resist UV?

A: Yes. Core components have passed rigorous High/Low Temperature, UV, and Accelerated Aging testing, ensuring long-term stable operation in extreme climates (severe northern winters, scorching southern summers, intense UV radiation).

Q: How strong is the wind resistance?

A: Engineered wind resistance design:

• Scale 8 wind – normal operation, stable signal

• Scale 10 wind – slight decrease in precision

• Scale 12 wind – dish remains intact when pointed skyward

Q: Do you support color and logo customization?

A: Yes. Default color is light gray. We support custom colors and printed logos based on client requirements – ideal for operator bulk procurement and corporate brand consistency.

Q: Is the packaging suitable for international shipping?

A: Yes. Packaging is designed for air, ocean, and land transport with professional protective structure to minimize transit damage.
