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's included in the price?
A1. Price is FOB Shanghai price.
Q2. What's the coverage?
A2. Coverage depends on many factors. Power of transmitter is only one of them.
So we can only say the coverage of 1000 watts FM transmitter is around 20-40km in radius depending on the other factors especially the height of antenna.
Q3. What's the suitable antenna for the transmitter?
A3. The antenna should be 50Ohm impedance which can bear 1KW power. Most suitable is our FM-DV1 dipole antenna.
Q4. Is the frequency and power adjustable?
A4. Yes, it is.
Q5. How does the purchase process work?
A5. Visit the website choose your like model contact seller Provide product information Quotation
Discussion Deposit Arrange production Balance payment loading
