Hello Elecrafters,

It is off-topic and you can press 'DEL' now.

Hong Kong is quite a hilly place in the rural areas. Local ham societies are 
often providing radio communication support services to charity organisations 
having fun raising sports activities in these areas.  We have to set up UHF 
repeaters at the hill tops.  Purely from the radio text books, a 3 element quad 
gives better performance than a 3 element yagi.  However, I seldom see using 
directional Quad in the UHF repeaters.

Apart from performance, are there any disdvantages (or advantages) of using 
directional quad instead of yagi in UHF repeaters?  Could you share with me 
your experience in US?

Thanks for your help in advance and please reply off-the-list to reduce the 
traffic in the mail listing (oh, yes, not forum!!)
