[QUOTE="Channel Hopper, post: 1005944, member: 175144"] In the same manner as upper Ku band, where the higher (Telecom) frequencies were better received once the dish manufacturers had made adjustments to their feedhorns and transfers (resulting in a slightly smaller diameter). The CPR229 specification is now commonplace but historically is derived from an earlier WG11 specification from the beginnings of GHz reception with dimensions of approximately 29 x 58mm. There is another port for this band however, mechanically smaller, WR187 which has dimensions of 22 x 47mm (again approx) and the centre frequency is better aligned with requirement of a super-duper wideband LNB. I would hazard a guess the latter might perform better at the upper 4.5-4.8GHz wavelengths. [/QUOTE]
