# Why shouldn't you use HF radio while refueling?

FCOM limitations for many aircraft state:

DO NOT USE HF RADIO WHILE REFUELING

Why is this? I have heard from people that it's because most of the big airliners have a 'notch' antenna for HF; it's a small notch cut at the base of the vertical stabiliser. HF transmission power is fed to this notch and the whole fuselage acts as an antenna, radiating the power.

Can someone explain in detail and in simple terms?
