[Repeater-Builder] Dielectric diplexer

[bil.isom]

I have just been told I am about to receive a dielectric brand diplexer rated 
at 25000 watts on 191 Mhz from a analog TV station.  I feel a little bit like 
the dog that catches the car he is chasing.  Now that I have it, what can I do 
with it?  Any ideas?  Can it go to 220? Does anyone have any experience with 
these? 
Thanks
