Yes, these new bands are very much about TX and RX antennas and dealing 
with electronic noise. I haven't been on the new bands yet, but I've 
heard that K1JT's WSJT modes like JT65 and JT9 that allow copy deep into 
the noise are quite popular there (and why I would also expect to see 
FT8 activity). NO3M was one of the first experimental licensees, and has 
a VERY impressive RX antenna farm.  Follow the Antenna links on  
http://no3m.net/ There's also a lot of detail on TX and RX equipment.
