FAQ

Q1. Is the Frequency Adjustable?

A1. FM Radio Band Frequency is 87~108MHz, TV Band Frequency includes UHF/VHF band.

For FM Radio Transmitter; Power Below 2KW is all adjustable. Above 2KW would be narrow.

For TV Transmitter; all Frequency Band is very Narrow, only can contain around 3 Channels; so it’s not adjustable.

Q2. Is your Analog TV Transmitter can be upgraded to Digital?

A2. Yes, we can. But the Frequency Band should be the same.

The only difference between Analog & Digital TV Transmitter is its TV Modulator.

After upgrade to Digital, the Power from TV Transmitter reduced 5 times.

For example: 1KW analog TV Transmitter can be upgraded to 200W Digital TV Transmitter.

Q3. How to do installation of these equipments?

A3. For small power station, the equipments are very easy for installation.

For large power station, we can send our engineer to your country to help you do the installation, but you should pay the cost.

We also can do training for your engineer here in our company.

Q4. How to operate these broadcasting equipments?

A4. We provide All-English user manual; All-English operation software in our equipment.

We also can do training for your engineer here in our company.

Q5. What about after sales?

A5. The warranty time is one year after goods leaving factory.

We can provide technical support from internet or in our company.

We can send spare parts to you directly when the equipment damaged.
