Make sure you balance the station receive performance with that of the 1 
KW amp.   Power is easy to generate.   Low noise receive performance is 
a challenge.   Start with a mast mounted low noise preamp, then low loss 
feedline such as 7/8" hard-line, and such. Remember, loss in the 
feedline adds to receiver noise.

I encounter many stations that have great signals but seemingly can't 
hear other stations calling them.  I call them alligators.......all 
mouth, no ears.
