FAQs
1. How much the consumption of that your transmitter with 2 Watts Power amplifier?
Almost 14 Watts consumption.
2. How much transmitting power “watts” do we need for 1km from ground to ground?
1W is enough for a 1km distance. But we will make 2W for you to ensure the best reception performance.
It also depends on your local environment, whether it is LOS or NLOS, please check our test video, there are many floors and buildings.
3. Is it possible to adjust the transmission power from 500mw to 10 watts? Through software or a button on the system cabinet?
For changing different power amplifiers about 500 MW, 1 Watt, 2 Watt, or 10 watts. It is not just adjusting the setting in the software, You also need to change the Power amplifier hardware inside the transmitter. It can not operate and change at the normal end-user, and the cost and transmitter metal box size are different.
4. Is it possible to change to 1.3 GHz band?
The default frequency setting is 503 Mhz, 509 Mhz, 521 Mhz, and 521 Mhz to choose, one button on the cabinet can change. If you really need a 1.3Ghz band only, you should choose another model (1.2G or 1.4G). Please tell us the details of your demand.
