Kinda funny. Antenna gain is beam width. Antennas with large effective apertures have narrow beam widths.

I can easily buy that it could be cheaper to launch a 50m spherical inflatable antenna than a rigid 25m parabolic antenna. But it's never going to be true that a spherical antenna with the same gain as a parabolic will have a wider beam width.



I assume some part of the "focal line" aspect changes that calculation.
