[QUOTE="Channel Hopper, post: 1074034, member: 175144"] WR75 is a specification with dimensions of 3/4 inch and 3/8 inch. I can't recall the max/min pass but it is about 8-15.5GHz. The transmit port on a Ku band BUC/ODU is at the upper limit of the frequencies but still shares the same dimensions of the WR75 specification. For reception that covers the upper frequency it might be worth looking at a mechanical band pass filter (of which I have some), or sleeving down the internal throat of the feed using thin aluminium. Something akin to a Chinese takeaway carton works well. I would aim for around 0.7 of an inch (or a shade over 17.5mm in new currency) [/QUOTE]
