Broadband switch during deicing/anti-icing

The 787 FCOM states:

If de-icing / anti-icing is needed: BROADBAND COMM switch ...................................... Off.

Why?

Not sure, not familiar with Boeing.
Whats your wavelength and what is the limit of your near-field radius where humans should not intrude into?

I'm guessing this is for a Panasonic eXConnect Ku band setup - here's the old FCC paperwork for their ground and flight tests:

Doesn't take much to exceed safe (legal) exposure limits, especially when you're potentially above the antenna in a deicing vehicle... Same reason you're not supposed to have the weather radar on or transmit on HF with personnel nearby.
