Common Problems:
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 your Power and Frequency.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.Depends on 4
factors:1.Power from Transmitter;2.Height of Antenna;3.Gain from Antenna;4.Around Environment.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?A8:Small power station is easy for installation.Large power station:we send engineer to do the installation, but you pay the cost.We can do training for your engineer in our factory.Q8.What about after sales?A8.Warranty time: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.
