[Moon-net] 23cms question

[M0EME Paul Tomlinson]

Hi all, I've been toying with the idea of trying out 23cms, I will probably 
listen only for a while.
What I have is two questions, the first is what size yagi would I need to 
have a worth while shot at this? and the second is, would I be able to put 
the yagi in the centre of my array of four FO19?? or would this totally ruin 
the pattern?
If the answer to the second question is yes it would ruin the pattern then I 
would make a bracket and only add the yagi when I want to listen in on 
23cms.
Has anyone any ideas on this???
Thankyou all Paul M0EME
