[QUOTE="casser, post: 593593, member: 264731"] Polystyrene have 2.5-2.6, but the expanded polystyrene have 1.02-1.08, put a brick of styrofoam in front of a dish it wont affect the signal..it´s almost vacuum. I will get a bag of styrofoam (loose form) and try some mixes with sugar to see if the Focal Point is affected, if have the same signal and the FC get´s longer...so using styrofoam with materials lower the dielectric constant of the antenna. Do you know what´s the impact of the "Loss Tangent" in these types of antennas? It can affect the performance of the antenna using a high "Loss Tangent" material? [/QUOTE]
