Here's a general question about dishes for the consideration of the collective wisdom …

Apart from the obvious 'advantage' of being able to feed it from directly behind the dish, what are the advantages of cassegrain dishes? Any disadvantages?

Also, I'm getting conflicting info from Internet searches about what shape the main dish is - is it the same shape as a normal dish (ie parabolic)?
What I'm really asking, I suppose, is that if I have a cassegrain dish, can I remove the sub reflector and use it as a PF dish?

Hi John,

There's another thread running on a very similar topic - viewtopic.php?t=5356&p=14794#p14794

Might be worth reporting your question there...

Haha, OK, Noel... I had read that thread but started a new thread as I didn't want to be seen to be 'hijacking' the Graham's thread

I'll add my post to that one.
