I got a remote video camera (a toy realy) which got a very limited range
(They clain 45m, but it is less).
It has a small antenna that looks like a dipole printed on a PCB (can't
see more than that through a few holes).

I would like to get at least a 100m out of it. Now, I had a brush with
radio signals in my studies fifteen years ago and I remember something
that a dipole size is a calculation of wavelengths. Can I make a bigger
dipole? Oh yes, it must be somewhat omni directional. What else can I
do?

I dont see any antenna on the receiver (haven't opened it up yet). Can I
do something here?

This is for hobby, me and my friend want to stick it in a R/C plane. So
we would like to keep the cost down.
