...and if so what can I do about it?


yes it seems so...I have seen the same thing with those devices.

it is very difficult to solve, you would need better antennas...

in your case it may be more practical to use a coax wired connection

For electrical saftey around water...be VERY careful that all
equipment is properly grounded, that the outlet grounds are wired
properly and I would also use GFI circuits.
