Product Description:

Multi-Frequency Band Vehicle Antenna

EV288

Description

The EV288 is a full-frequency vehicle antenna that supports GPS, BDS, GLONASS, and GALILEO. It is suitable for use in a variety of contexts, including automated agricultural equipment, high-precision UAVs, and vehicles mounted with the antenna. It is particularly well-suited to applications involving high-precision automated agricultural machinery, such as high-precision tractors, plant protection machines, cultivators, and harvesters.

Technical Features

1. The passive antenna exhibits high gain, a wide beam width, and a low elevation angle signal reception effect, rendering it capable of receiving satellite signals in environments with significant obstructions.
2. The passive antenna with a wide working band is capable of supporting multiple systems and frequencies, including L5, B3, LBand, and other frequency points, thereby enhancing the stability of the system.

3. The device is characterised by a small size, light weight, reliable structure and protection level up to IP68, which significantly enhances the reliability of the machine. This includes waterproofing, vibration resistance and other such features.
4. The device exhibits a robust anti-interference performance, with high antenna out-of-band suppression, which effectively mitigates base station and other signal interference caused by system instability.

Application
• Unmanned delivery vehicle	• Self-driving truck
• Self-drive bus	• Self-driving cab
• Unmanned & unpiloted	• Plant protection drone

Note 1：

Hello! Thanks for your interest in our vibration test description. We're excited to share the details with you.
So, the external antenna should be able to maintain its structural integrity and work normally after undergoing a vibration test with a frequency of 1-30 Hz and a single amplitude of 0.75 mm for 50 minutes on three mutually perpendicular axes. It should also be able to maintain structural integrity and work normally after undergoing a vibration test with a frequency of 30-55 Hz and a single amplitude of 0.25 mm for 25 minutes on three mutually perpendicular axes.
We hope this information is helpful! Please don't hesitate to reach out if you have any questions.
Impact test description: We just need to make sure that the external antenna can keep its structural integrity and work normally after being subjected to the impact test with an acceleration of 50m/s² and a duration of 18 ms for 18 times.
Let's talk about the salt spray test! The salt solution has a mass percentage concentration of around 5%, with a pH value of 6.5-7.2. The spray lasts for 2 hours, with a 22-hour interval for storage. The antenna goes through 3 cycles, and it's great news that the surface doesn't corrode! The antenna is still working perfectly.
We also want to test how waterproof the antenna is. To do this, we'll randomly drop the antenna three times from a height. It'll be dropped in any direction, and we just want to see that the shell is still intact and that it still works normally.
