antenna they will destructivly combine.

If it actually radiates and if that radiation destructively combines
at one receiving antenna, then radiation must constructively combine
at another (potential) receiving antenna, or else the conservation of
energy principle would be violated. Any far-field destructive interference
event must be exactly balanced by an equal magnitude constructive
interference event at some other location in the far-field. If there is
a receiving antenna there, it will experience gain over the first location.

And a coiled up antenna is likely to experience a lot of I^2*R losses.
