FAQ

pātai: He aha te mea ka wera rawa te anga ma te hiko i runga i te tuku?

Whakautu: Tuatahi, i whakamatauria e matou tenei poari ara iahiko i nga pāmahana iti 40 tohu me 85 nekehanga. Ka tino wera te ringa, karekau e pa ki te whakamahi noa o te kaiwhakawhiti.
Tuarua: E rua nga take he ahua teitei te pāmahana o te keehi:

1. To be waterproof, karekau he kohao tohanga wera me nga kohao powhiriwhiri i a maatau casing.
2. To support 50 kiromita, kei a matou he whakakaha toru-watt kua hangaia. Ko te whakakaha hiko e hiahia ana he powhiriwhiri whakamatao. Ko te maramara me te poari o te whakakaha kaha e tata ana ki te pouaka whakarewa hei whakawhiti i te wera.

pātai: He taumaha te ahua o te anga o tenei kaiwhakawhiti, a kaore e pai mo te whakaurunga ki runga i te haruru me mama, matau?

pātai: He aha te mana o te kaikawe kaore he taapiri taapiri? 100-200MW?

pātai: He aha i nui ake ai to utu whakawhiti ataata FPV i te kaiwhakawhiti ataata tairitenga UHF?

Whakautu:

1. Ko tenei kaiwhakawhiti ataata FPV ehara i te tuku ataata tairitenga FM-modulated noa.

pātai: Can we assemble the repeater by ourselves using two sets of receivers and transmitters?

Whakautu: Pono, 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, tuku, 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. Tena koa tirohia te pikitia i raro nei. We have put the receiver and transmitter in one box.

There are two frequencies, hei tauira, 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 karamu, 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.

pātai: What is the idea of using two of the same antennas on the receiver?

Whakautu: 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.

pātai: What is the bandwidth of the channel?

Whakautu: The default is 6Mb. You also can change it from 2MB, 4MP, 6MP, 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.

pātai: Can I combine a directional antenna with a circular?

pātai: Is it possible to set the input and output video type manually (PAL / NTSC)?

Whakautu: PAL / NTSC both support, auto-detect, and switch according to your input camera.

pātai: We need a configured board for the transmitter. How much it costs?

Whakautu: 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, penei i te auau, hōkaiipurangi, AES password, etc.

pātai: Does the receiver have analog and HDMI output?

Whakautu: Ae, 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.

pātai: Extra wave filters for drones – we need this (how much does it cost?)

Whakautu: 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.

pātai: We need a direct RF antenna input in the FPV video transmitter metal case. Can you make it?

pātai: Is the power of the transmitter and receiver 12 volts? What amperes?

pātai: What are the default settings for this FPV camera transmitter and receiver? (How to reset to factory settings)

FAQ

1. Does your FPV video transmitter work well in the jammer at the below frequency?

Whakautu:

The default frequency is 595Mhz, (the center working frequency of the power amplifier and antenna is 595Mhz, ) I checked that this is not the range of your table mentioned. A muri ake nei, the anti-drone jammer may cover 595Mhz, we also can preset different frequencies chosen from 170-860Mhz.

2. How can I transmit telemetry of the flight controller with overlay on the video channel?

MinimOSD is the function to transmit telemetry of the flight controller with overlay on the video channel.

3. Does your FPV camera transmitter support transmitting 1-way data as telemetry to the ground?

Tautoko.
