Hi all. This is my first post here. I figured I'd try out these forums and see how the community is here.
I built a TriCopter using mostly David W's design and it is awesome. Have a multiWii pro3 black board on it and it works great. So the next logical step is FPV right? So I have my gear but want to build a cloverleaf antenna for my transmitter.
I see that the measurements using the calculator are down to the hundredths of mm? Really? I can cut it close and then solder it a little high on the center conductor of the coax and be way off according to these numbers.
My question is is there an antenna length that I can use when I build a cloverleaf antenna so I can use more than one frequency. Obviously it will work best for the frequency that I cut it to but being new to FPV I may need to jump around to the other channels.
From the chart I found I see that from the lowest freq ch4 @ 5.645Ghz to the highest freq @ 5.945 Ghz the measurement for each element would be from 57.44mm to 51.64mm. Can I split the difference and go 54mm? I looked at readymaderc site and he sells ibcrazy antennas but they are not for a specific channel or at least I did not see that in the description.
So is there a happy medium that I can use for my dimensions?
Thanks!
Mike
