Common Problems:

In order to be more comprehensive understanding of the knowledge about our products,we collect all the analyses of problems for every order,hope it will help you. 

Q1. What these equipments used for?
A1. We are original manufacturer in FM Radio & TV Broadcasting equipments; they are professional used for FM Radio & TV Broadcasting Station (Transmitting equipment.)

Q2. What equipment & solution your company can provide?
A2. We can do complete solution for FM Radio Station System. It includes:Studio--Link--Transmitter--Cables--Antenna.
We also can provide complete Transmitting part of TV Station. It includes:Link-Transmitter-Cables-Antenna.

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. How to do installation of these equipments?
