The dipole looks too small to be C band but the F type is not good for Ku. Is there an LNB in the back section?

Not really an antique, there are some nice examples around though nobody has an idea what dish they used for testing.

Yes, iv'e seen these advertised before about six or so months ago and was tempted to have a dabble with the top feed unit to satisfy the operational performance curiosity of the thing but had to 'resist' pushing the button.

Feedhorn or Horn antenna ?

Feedhorn or Horn antenna ?

Both really, see how it illuminates on my 2.2 as shown in the pics out of curiosity and then just experiment after that. Iv'e got a multi lnb changer 90% built to have a dabble with on my 2.2 PF reflector when the warmer weather gets here hopefully and that Chaparral unit could come in handy on the changer.

The aperture of the horn is unlikely to suit a PF reflector, I tried a while ago on the 3.4m as it is quite a shallow. No better than a mis-shaped scalar.

I like the fact that the horn is easily detachable lending itself to easier feed experimentation and the design of the intergrated servo polarity into the lnb itself is something iv'e never had any dealings with before so curiousity is setting in - i'm only at the stage of looking and pondering at the moment though
