Looks like a big Opera   set up

But  for  LF , may be  not , the  description   talks  of a  wide  band  Rx 
, so  there  making  a  comb  spectrum  to  feed  the  Rx over its  b/w

as  for the  phasing  / frequency  match , I guess , there  using  distance 
, ie , some  one will  be at peak  at  any   time  during the  slot , so the 
qrg/phase is not  important  as  the  received energy will  be  'constant' ?

G,
