[QUOTE="steffo78, post: 179015, member: 196557"] A sphere has its focus on 1/2 radius but it is not really focused there so you lose some gain. I dont know how much worse it is compared to a parabola. I have seen antennas with sphere-design horizontal and parabolic vertikal, I think it is called Torus and were made by SMW, but it is not effecient compared to size. [/QUOTE]
