go with what jeff has said .. your radious will increase 10 fold if you get in a plane . do what jeff said as far as the antena and coax tape the antenta to a wing strut and .. If your receiver has a place for a head set . use it .. it will drown out the engine noises from the plane..and you can hear the beep better.. you can also have your husband on the ground and call him and direct him.
when I was flying falcons and lost my bird .. I almost always had a signal when i got up in the plane ..
good luck...
You might also call the police in the area in case they get a call .. they can call you.
