Hi Filipe,

That's the best solution, assuming that you have a tuner in the shack 
(or an amplifier with a tuned output that can handle a modest mismatch), 
and that you are using big coax (RG8, RG213).  The loss in coax is so 
small on 160M that it doesn't matter unless it's a VERY long run. Yes, 
there will be standing waves on the antenna, but with the dimensions 
you've listed, they should not be high enough to cause overheating or 
voltage breakdown.
