I have an experimental setup like so:
And if one looks closer at the lens, there are metal poles near the bottom of the lens (the extensions of the stands beyond the clamps) that are obstructing the path of the wave. Does their presence influence experimental results in any way at all? Since the transmitter is conical, the waves radiate like a cone. Also, (since this is a question related to the same experiment, I will ask this here) there is a dipole receiver. Does the axial or transverse orientation of the dipole receiver affect the readings taken?
