FAQ

Q: I want to buy the product shown below: COFDM-908T Full Set Wireless Video Transmitter and Receiver Yagi Antenna 20-Watt or 50-Watt.

A: Thanks. What frequency do you need? The default is 595Mhz, We can make the frequency range from 200Mhz to 860Mhz. If you confirm the frequency, then our power amplifier and antenna are customized according to the center’s working frequency.

COFDM-908T Full Set Wireless Video Transmitter and Receiver Yagi Antenna 20W or 50W

Q: Can you make the working frequency at 1400Mhz?

A: COFDM-908T is a one-way transmission, the COFDM wireless video transmitter supports a frequency range from 170-3500Mhz, but the COFDM wireless video receiver frequency only accepts 170-860Mhz. You need to install the frequency down converter at the receiver. If your clients tell you that he needs COFDM-908t, maybe he already knows our products. So you can use the default frequency at 595 МГц.

If you still need 1400Mhz, we also have the two-way transmission model support. it can download video and control the plane. https://ivcan.com/t/two-ways/

Q: Can I use the 50-watt PA COFDM Wireless Video Transmitter on the plane?

A: The 50-watt transmitter needs to be packed in a big iron 2U standard box. 50-watt PA is too big, and it needs a lot of heat dissipation. The 50-watt transmitter is almost 7.5kgs.
How far do you want to transmit? Why do you need such a large transmitter amplifier? Well, the engineer said that the iron shell should be very big, otherwise the heat dissipation is not good and it is easy to burn. So I want to know your real needs, I don’t want you to waste money and time.
Our 10-watt can transmit 150 kilometers, на 50 watts, you need a bigger power supply and battery. It’s not that the bigger the amplifier, the better, because the earth is round, and there will eventually be an obstacle.

Q: My client confirmed that it will be installed on the moving car.

A: Thanks. Then it is no problem. We recommended that you use one 180cm fiberglass omnidirectional antenna on the car.
There are two antennas at the COFDM Wireless video receiver, we will prepare one 180 cm fiberglass omnidirectional antenna (8.5dBi)and one 167 cm Yagi directional antenna (14.5dBi).

I will show you a 50-watt HDMI transmitter and receiver in this video. Open the metal shell, you will see the frequency filter, 50watts power amplifier, cofdm transmitter board, power transfer converter from 220-28V, and power converter from 28V to 5V for the parameter configuration panel. These are all assembled in a standard chassis. A 50-watt power amplifier requires good heat dissipation space.

Let’s take a look at the transmitter’s parameter configuration panel.

The default frequency is 595Mhz, 6M bandwidth, Let’s check the transmit power, 50 watts need 47dBm. In the video, we used a 40dBm attenuator. After attenuation, the current measured power is 6.61dBm on our testing tool. Before shipment, we will take a video of the power test. The attenuator is 40dBm, plus the current test result is 6.61dBm, and there is a small amount of loss in the current RF line.

We can also customize filters with different transmission powers according to your needs. The 50-watt power amplifier COFDM video transmitter has two power supply modes, 220V or 28V. 28V has 5.7 Amps.

The parameter control board installed on the shell can adjust the transmission frequency, and bandwidth, increase attenuation, тощо. You can also enter a password on the transmitter, and you need to enter the same password on the receiver to ensure that the video you transmit is encrypted. To prevent others from receiving your video on the same frequency. Encryption does not increase video latency.

Let’s take a look at the video clarity. It supports 1080p full HD video. We waved our fingers before the camera and saw no visible video lag or freeze. If necessary, we can also place a millisecond stopwatch on the camera to calculate the exact delay. Please see it in other videos. low-latency delay test of COFDM transmitter-receiver for 4-video PTZ camera 2-way audio data link

This 50-watt PA COFDM HDMI transmitter is an absolute game-changer for long-range, high-interference environments! The massive power amplification delivers incredibly stable HD video links up to 30km, effortlessly punching through urban clutter and rough terrain where our old systems failed. The built-in filter is genius – it completely eliminates harmonic noise that used to plague nearby equipment. I love the dual voltage input (28V/220V); it seamlessly integrates with both our drone batteries and field generator setups. Despite its raw power, the heat management is superb – it ran cool during a 6-hour live broadcast in 35°C heat. For remote news teams, industrial inspectors, or anyone needing rock-solid, cinematic-quality video transmission where others can’t, this beast is worth every penny. Zero dropouts, zero regrets!
