At the 10 m level on my tower, It isn’t bothered by 1500 W on any HF band and

the lithium 123 cells used to keep it going at night after the supercapacitor has been
discharged.
Two reasons why wireless systems aren't usually susceptible to HF RF --
very wide frequency separation, and no wires to act as receiving antennas.
The problem with RFI FROM wireless stations for weak signal UHF suggests
a wired system -- IF you don't also run power on HF. :)
And if you're running a wired system around HF, use the best twisted
pair you can buy, like CAT5/6/7, and wind turns on both ends around #31
cores.
