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. 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?
