    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

    TV 100w, 300w, 500w, 1kw, 3kw, 5kw, 10kw

    Digital TV 100w, 300w, 500w, 1kw

    We also produce the rare power according to customer’s requirement, such as, 2kw, 4kw, 7kw

    The minimum power we can produce is 15w and maximum power we can produce is 20kw.

    6.Package and transportation

    We adopt international standard fumigation wooden case. It is also according to customer’s requirement. 

    As to the transportation, our products can be transported by sea, by air or by train.

    7.Warranty and after-sales service

    It is one year after delivery. For the non-personal fault, we offer free maintenance and spare parts. After the warranty, we only charge the cost.

    8.Installation and debugging

    We can offer the service of installation and debugging. The buyer should provide the salary, room and board of our staff, as well as arranging the translator. Our staff only takes in charge the installation on the ground. We don’t take the aerial work and heavy manual work. The infrastructure construction and signal source should be offered by the buyer and settled before our staffs arrive at the site.

    9.How about the shipping?

    For small orders, we will send the goods by International Express like HK Fedex, DHL, TNT or UPS. usually it takes about 7work days to arrive.If big quantity we will ship by Ocean transportation, it takes one month to arrive. if urgnet, you can select shipping by Air, but freight charge will be more expensive.
