1. Introduction of drive away SNG antenna system

Normally drive away SNG antenna is equipped with high performance electronic compass, inclinometer, GPS, beacon receiver and other sensors, with design of one button starting, auto-pointing, which can acquire any satellite within 3 minutes of high positioning accuracy. We develop software and control mechanism (Servo-motor) for positioning to close the link with the Satellite that the customer programs in the controller unit. This segment provides antennas in C-band, Insat C band, Ku, Ka and X-Band with various diameters (from 1.2 meter–4.5 meters). Please let us take an example as Antesky 1.8m drive away SNG antenna, kindly check this antenna information on the website.

2. System Componentsof drive away SNG antenna system

Feed subsystem: one piece of carbon fiber reflector petal and offset feed.
Turntable subsystem: 3 axial turntable including Az, El, Pol.
Servo control subsystem: antenna control unit, antenna drive unit.
Position acquisition subsystem: digital compass, GPS , inclinometer .
Receive subsystem: beacon receiver with high sensitivity.

3. Product features of drive away SNG antenna system

Easy to install on top of commercial vehicles, off-road vehicles, SUVs, MPVs and military cabins without wearing a roof. please view this video that 1.8m vehicle- mounted antenna installed on bracket at our site for details.
High precision configured GPS and strong anti-interference electronic compass which ensures the environmental adaptability and the program accuracy to the satellite.
The antenna automatically point the satellite with no more than 3 minutes (RMS).
Automatic warning, mechanical limit, software limit of protecting devices makes the antenna safer to operate.

4. Application of drive away SNG antenna system

Antesky Drive away SNG antenna system is a compact, quick deployable and automatic pointing antenna system that suits for the most demanding applications like SNG (Broadcast) customers, mobile broadband Internet access, disaster relief, oil and gas data backhaul, and defense and homeland security around the world. This antenna is suitable for C-band satellite communication,and is widely used in defense security, government emergency communications departments, telecommunications, news media, public security, border defense, armed police, military, scientific expeditions and other fields.

Antesky 1.8m JZT180 Drive away SNG antenna system is one of our best-selling products, which is very popular in the market because of its excellent product performance and reasonable price. Customers from South America and Asia feedbacked to us that our antenna with low noise temperature and high gain can well meet their receiving and transmitting needs.

As we know that the 1.8m vehicle antenna is driven to the magnitude by the electric part, and can also be manually controlled when necessary. For mechanical products, it is very necessary to regularly maintain and maintain the motor transmission parts, connecting shafts and other components. This article will provide some maintenance methods for your reference.

5. Common problems and solutions of drive away SNG antenna system

Item	Description	Possible reason	Solution	Notes
1	After power on, the controller screen does not light up.	-Power cord not plugged in – Fuse burnt	-Check whether the power supply is normal. -Check if the fuse is burned out.
2	Sudden power outage while the antenna is running.	Power cut	Turn the azimuth and elevation with the hand crank to stow the antenna.
3	The signal value fluctuates greatly	Poor RF cable contact	Find bad spots and re-solder
4	When there is a large difference between the actual orientation of the antenna and the degree of the compass	The compass receives a lot of external interference	Move the antenna out of the interference area, and if it fails, increase the antenna search range.
5	There is abnormal noise when the antenna is running	Internal gear lubrication problem of turntable	Add lubricating oil
6	The antenna arm cannot land naturally	Gas spring problem	Replace the gas spring or add lubricating oil to the gas spring.

Under normal working conditions, the antenna should be regularly maintained. The main contents of drive away SNG antenna system maintenance are shown in the following table.

NO.	Repair and maintenance content	Maintenance cycle
1	Regularly check the damage of the PTFE film of the feed horn, and replace it in time if it is damaged.	Once a month

2	Regularly check the waterproof condition between the duplexer and each waveguide. If there is water seepage, dry it in time, and seal it with 704 glue or replace the damaged parts.	Once a month

3	Regularly check the looseness and corrosion of the screws, and if they are loose or corroded, fasten them or replace them with new ones in time.	Once a month
4	Regularly check whether there is any abnormal noise in the transmission of the antenna during use. If there is, clean up the foreign matter in the transmission part or lubricate the joint part.	Once a month

5	Regularly check the surface coating of each part of the antenna, if there are serious scratches, please deal with it in time	Once a month

6	Regularly clean the feed horn film to ensure the signal is not affected	Once a month

7	Clean gas springs regularly and replace every three years if necessary	Once a year

8	Regularly inspection of azimuth, elevation and polarization drive belt wear, and replace wear parts every three years	Once a year

9	Regularly calibrate the antenna compass to ensure that the antenna can quickly find the satellites.	Once a year

10	When the antenna is not in use, please stow the antenna in time; if it is not used for a long time, please place it indoors to avoid wind and sun.	Long term

11	It is recommended to maintain the drive mechanism part every year to ensure the lubrication between the gears	Once a year

12	It is recommended that the antenna surface be cleaned every three months	Long term
