SteppIR is not what you want for contesting with multiple radios and 
quick band changes. If you don't care then it is fine.  As I get older, 
I am only 54, and young I have less and less desire to climb or do 
antenna stuff.  The SteppIR's can require more service.

What I would do is copy what W2RE is doing with the Remote Ham Radio stuff.
