Hey.... Maybe we can use it as a buffer amp in your planewave 
antenna to verify the low frequency performance (where the 
termination starts opening up below 150KHz).
My 50ohm HP33120A signal generator can do that into a 0.0015pF load 
too :o)))  Trust me Gerry, it is flat ;-)  You just take the output 
of the generator to a pop can right "near" the antenna and you can 
sweep around all you want.  At say 100MHz, things get messy, but 
200kHz is simple ;-)
