F/D ratio ?

Why are you trying to polarise signals on Ku band ?

Your best bet is to use a narrow band LNB with external reference (SMW or similar)

That is - probably the 'f'. If the true diameter is 3.8 then the f/ d of your the Patriot works out at about 0.39.

They are available, but I'm not sure why you require a four port unit


The type of dish does not determine the porting, but the feedhorn assembly flange, though some designs use the collar for clamping.
