FAQ

1.How can i get a sample ?

You need place sample order to us.We will arrange the sample production for you.

2.OEM,ODM Service is available?

Yes,AGBE have strong ability to offer customers ODM&OEM products of highest quality.

And it will require the MOQ.

3.Coverage of FM transmitter and TV transmitter.

The main parameter which decides the coverage is height of tower, so people install the antenna on very tall tower or build the tower on top of mountain. The signal has attenuation in air transmission, so people use large power of transmitter to supply the power loss. In a word, the main reason of coverage is relative height of tower to ground, secondly is power of transmitter, thirdly is antenna gain.

4.How can I know my coverage.

You can tell us the power of transmitter you have and height of tower plus coordinates if possible, then we can calculate the coverage for you.

5.How can we place order

After we made agreement on the product' parameters, we will make proforma invoice for your confirmation.when we got your advance payment (deposit) we will arrange the production and delivery.

If you have your own ship forwarder, we will use your ship forwarder to delivery goods. if you don't have ship forwarder, then when the goods arrived at Destination port, you must find a ship forwarder help you clear the custom.

6.How about the shipping?

For small orders, we will send the goods by International Express like HK Fedex, DHL, TNT or UPS. usually it takes about 7work days to arrive.If big quantity we will ship by Ocean transportation, it takes one month to arrive. if urgnet, you can select shipping by Air, but freight charge will be more expensive.

7.How about the Warranty?

There are 12 months for the warranty.

While the warranty is not responsible for those broken by violence or updated with other brands.
