Yeah, but it would have been worthless for calling for help from the M4, M8 
or M16 you could see off to your left.

Nope.  The WW-II US tactical FM equipment topped out at 38.0 MC.

You'd do the same thing you would do if you were carrying a BC-1000 or any 
of the four late Korean War sets, do without.  They weren't issued with 
spare antennas.  Although admittedly, the short range ribbon antenna would be 
less prone to breakage.  But again, if you got into trouble, there wouldn't 
have been anyone to talk to anyway.  

As I said earlier, the sets in use in 1940 when the specs were set were all 
low HF.  20-20 hindsight is never fair.
