If the antenna is *in* the intense gravitational field, then I suspect 
that the physical antenna will collapse long before there would be any 
notice-able effect on the EM. Or it will be "sucked" into the field source.

But, the fact that EM is distorted in a *very* high gravitational field 
(like light passing through the gravitational field of the sun and 
getting bent in its path) helped Einstein get his Nobel.

All The Best,
