gilUriel 0 Posted October 8, 2008 Report Share Posted October 8, 2008 Hi, I have started experimenting with live video from my Trex 450. I placed a cheap 1.2Ghz pinhole ebay camera on it, build the patch antenna from this site (unbelievable change in reception) and I'm receiving it on my laptop. Not too bad ... But .. At some point the little wire attached to the camera's TX PCB went lost ! I looked at the web and found all the wave length calculators. one more BUT ... Should I use half length ? quarter length ? What kind of wire ? Also, anything that may make transmitting better will be appreciated. Thanks - Gil Quote Link to post Share on other sites
Terry 5 Posted October 8, 2008 Report Share Posted October 8, 2008 Some of those cameras use very odd lengths but 1/4 would be a good choice. Terry Quote Link to post Share on other sites
Vrflyer 0 Posted October 8, 2008 Report Share Posted October 8, 2008 the size of the wire is not important, but lenght is critical. I would use 1/4 waves Quote Link to post Share on other sites

Do I have a way to meture the exect frequancy that my tx uses ? (I know it is basicly a 1.2Ghz but its probebly not precise) - I don't have an RF equipment but I do have a scope. Ideas ?
