Paul,

Wilkinsons are not really the best way to go as you need high power 
floating 100 ohm resistors.

see: http://www.ham-radio.com/n6ca/microwave/rptr.html

These older 57762 power modules are combined with Sage "wireline" and 
they work great.  These are rated at 100 watts and they have a 200 
watt vesion available.  The good news is they have a gounded 50 ohm 
isolation resistor.

They ae very easy to work with and only cost $18 per foot.  I can 
ultimately furrnish the exact details on their use but there are some 
application notes on their web site.
