Recently I have had an opportunity to test this video transmitter over the recent weeks to see how it performs
Specs:
- Switchable power output (25/200/600mw)
- 40 Channels
- 7-28V input power range
- Built in microphone
- Weight: 13g
At close look
Video transmitter comes in a small case with whip antenna and cable needed to connect it to a quad. There is two buttons instead of dip switches and 3 sets of LEDs indicating:
- Band
- Power
- Channel
Top button is for changing the output power. Bottom button is for changing bands (long press) and channels (short press).
Testing
I have installed VT241T on Lumenier QAV-ULX quad to test the transmitter in the air.
The most important thing for me was how does it perform on 25mw (crucial at racing events). I have found that generally on 25mw it was pretty clear. There was some noise in-between the trees but with others flying with me there wasn’t much bad interference .
At 200mw and 600mw video was also quite clear. I haven’t personally seen much difference between the two power settings in the forest location I was testing it. 600mw makes the most sense if an aircraft is much further away.
DVR Video at 25mw
DVR Video at 200mw
DVR Video at 600mw
Conclusion
Overall not a bad video transmitter. It offers switchable power for a relatively low price. Changing power, band and channels is very convenient with two buttons and LED indicators meaning no more dip switches. Supplied whip antenna performed very well. Didn’t notice much difference in performance between that and ImmersionRC Spironet.
