    1.Cover range 

    Regarding the cover range, it related to the height of hanging location of antenna to cover area, for example, if antenna hanging height is 100m, the cover radius of 1kw fm transmitter is 30-40km. If the antenna hanging height is 50m, the cover radius of 1kw fm transmitter is 20km. That is, if the hanging height is lower, the signal gain attenuation is much more. Different power, different hanging height, the cover range is different. If you want to get larger coverage range, you can make up synchronous transmitting network to enlarge the coverage range. Usually, in the fm, vhf and uhf band, a transmitter can cover a city/town. Because the earth is round, it has curvature. 

    The reference cover range is showed as follow:

    Take the 100m hanging height as example,

    Power   cover range 

    1kw     30-40km

    3kw     40-60km

    5kw     50-70km

    The power is more than 5kw, the tower height is suggested to be more than 140m.

    2.We can produce

    We can produce the transmitter according to the customer’s requirement. Regarding the input power, it is can be adjusted according to the customer’s local condition, as well as equipping monitoring system and timing switch system.  

    3.Terms of payment

    L/C and T/T

    4.Delivery period

    It is according to the customer’s quantity requirement. For example, 1kw, it will take about 7 working days after the contract effective.

    For 3-5kw, it will take about 15 days.

    5.The products we can produce

    FM 30w, 100w, 300w, 500w, 1kw, 3kw, 5kw, 10kw, 15kw
