Q3. How large areas can One Station cover?
A3. One FM or TV Station can cover one city or one town.
The Maximum cover ranges of one station can not over 100KM Radius because the Earth is Curve.
You can use Multiple Stations & Different Frequency to cover larger area.


Q4. How do I choose suitable equipments for my station?
A4. The most import factors are Power and Frequency.
We need to know the Power and Frequency you need exactly.
How long the distances do you want to cover in Radius?
How height your Antenna can be installed?


Q5. How to calculate Broadcasting equipment Cover Range?
A5. The Cover Range depends on 4 factors:1. Power from Transmitter; 2. Height of Antenna; 3. Gain from Antenna; 4. Around Environment.
Then we can know the cover range of your station.


Q6. Is the Frequency Adjustable?
A6. 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.


Q7. Is your Analog TV Transmitter can be upgraded to Digital?
A7. 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.


Q8. How to do installation of these equipments?
A8. 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.


Q9. How to operate these broadcasting equipments?
A9. 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.


Q10. What about after sales?
