Pitakonan: Can we assemble the repeater by ourselves using two sets of receivers and transmitters?
jawaban: Mesthi wae, you can do like that.
If you need a relay and also control the plane, we recommend that you choose TX900, which just uses three units that can be formed a complete networking, pemancar, repeater, and receiver.
If you just need a one-way transmission system to download the video from the UAV to the repeater or ground. We recommend using our FPV repeater devices. Mangga dipriksa ing ngisor iki Gambar. We have put the receiver and transmitter in one box.
There are two frequencies, Tuladhane, 800Mhz from the transmitter to the repeater, and 300Mhz from the repeater to the receiver
To avoid interference, you also add two filters, and PA in the repeater module to increase the signal strength.
The above picture is from our engineer, he has a real sample now. The two filters and repeater are not in one box, if you confirm the order, we will do another casing or do casing by yourself according to your uav.
Relay or named repeater, which is a Kit for video re-transmission to extend the range.
The repeater with two filters is almost 450 gram, not including the antenna.
If the relay has two filters, is it still necessary to add a filter for the transmitter and receiver?
It is better to add a narrowband bandpass filter so that the reception performance will be very good.
Pitakonan: What is the idea of using two of the same antennas on the receiver?
jawaban: There are two diversity antennae on the receiver. One is ok, two is better, to get more signal from the transmitter, and increase the reception performance.
Pitakonan: What is the bandwidth of the channel?
jawaban: The default is 6Mb. You also can change it from 2MB, 4MB, 6MB, or 8MB if you want and buy the extra parameter tool board for the transmitter. It is better that you test at our default setting.
Pitakonan: Can I combine a directional antenna with a circular?
Pitakonan: Is it possible to set the input and output video type manually (PAL / NTSC)?
jawaban: PAL / NTSC both support, auto-detect, and switch according to your input camera.
Pitakonan: We need a configured board for the transmitter. How much it costs?
jawaban: To reduce the transmitter’s gross weight, the configure tool of the transmitter is external. If you don’t have it, the system is also working well at our default setting. If you have it, you can change the parameters of the transmitter, such as frequency, bandwidth, AES password, etc.
Pitakonan: Does the receiver have analog and HDMI output?
jawaban: Ya, the receiver has both analog (CVBS, composite video output) and HDMI video output.
In order to lower the video latency, the default setting, HDMI is only a video signal, no audio signal.
Pitakonan: Extra wave filters for drones – we need this (how much does it cost?)
jawaban: The FPV transmitter inside already has a low pass filter inside for the drone. Please tell us what requirements do you need.
Frequency Filters have two types, one is a low-pass filter, such as the working frequency is 595Mhz, then over 610Mhz can not be passed. Another filter type is bandwidth pass filter, such 580~610Mhz can be passed, others can not be passed.
Pitakonan: We need a direct RF antenna input in the FPV video transmitter metal case. Can you make it?
Now We designed the 45-degree tilt angle to be convenient for the transmitter antenna facing the receiver to increase the reception performance.
