Hi,
I know almost nothing about RF stuff, but I want to increase the consistency of my RF trigger and receiver units that trigger my camera flash remotely. My Trigger and receiver operate on 433mhz, and are supposed to have a range of 30m, but I can't even get them to operate consistently within 20ft. I am looking for possible (cheap) solutions.
Here is what I know about them:
The receiver (green circuit board in pics) runs off of 2AAA batteries. What appears to be the antenna is a wire that sticks up from the circuit board, runs parallel to it for about 3/4", and then reconnects to the circuit board. (bottom left side of pic)
The Transmitter (blue circuit board in pics) runs off of a small 12v battery (shorter than AAA). What appears to be the antenna is a wire connected to one corner of the circuit board, running parallel to it for approx 2" and unconnected at the other end. (top of circuit board in pic)
1. Would increasing the antenna length help?
2. If so, is it better to buy an antenna, or can I use wire to extend the antenna?
3. Would it be better to extend the trigger or the receiver antenna?
Thanks for your help
