Why must every perceived problem be resolved by buying something? All 
Elecraft rigs, including the KX2, have an indicator for SWR that the rig 
sees. Resonance can be clearly seen by moving up and down the band to 
find it.

SWR is NOT an indicator of how well an antenna works, and antennas don't 
necessarily have to be resonant to work well! That depends on how we use 
the fundamentals of how antennas work. Especially when using improvised 
wire antennas with little or no feedline, the only thing that matters 
beyond the fundamental properties of the antenna is whether the rig can 
match it.

I'd be far more likely to drag along more "stuff" with which to rig 
improvised antennas in whatever surroundings I find myself, and to study 
the ARRL Handbook and Antenna Book to understand those fundamentals.
