Yes, the frequency can be changed from 170Mhz to 860Mhz.
The frequency should be modified to the same on the transmitter and receiver. Of cause, the Power Amplifier and antenna frequency should modify the same frequency.
The default frequency is 590Mhz, With 30Mhz (+/-15Mhz), you can change it without modifying the Power Amplifier and antenna. For example, 578Mhz, 584Mhz, 590Mhz, 596Mhz, and 602Mhz.
Yes, it supports to send the video and UART data from the transmitter and receiver.
As it is one-way transmission, so it can not send the control command from the receiver to the transmitter.
The transmitter default Power Amplifier is 2 Watts, so it can support 30 KM at line-of-sight.
The below picture is our tested distance from the mountain to the seaside.
Yes, if you need, we can change 5W or 10W PA to support longer distance.
Step 1: Please press OK and the right button at the same time, a menu of whether to save appears on the screen.
Step 2: Please press OK to choose Yes to save.
The power supply of this transmitter and battery both are [email protected]. At the normal time, the battery we used for tested is 7AH, it can work for 2~4 hours. If you buy15AH chargeable battery, it can work continuously for about 4~8 hours.
Not only switch the frequency at the web UI parameter easily, after changing the frequency, it also needs to change the Power Amplifier inside and the same frequency transmitter and receiver antenna. So buyer should confirm which frequency you need before delivery. The antenna is customized according to this frequency.
Regarding the RF cable, our engineer doesn't recommend that you used so long. There will be a reduced 0.5dB for one meter RF cable. For 3 meter RF cable, the signal strength will be reduced by 1.5dB.
In order to support long-distance at the, Can you use the RF cable is less than 1 meter?
In fact, the transmitter is very smaller, it is better to keep a short distance from the transmitter to the transmitter antenna. The power supply cable for the transmitter and ethernet cable from the camera to the transmitter can be longer as there are no losses like RF cable.
