Speaking of basics- the following paragraph is from an Extra class, on
another reflector:
>Not So! And RF signal consists of an electric field and a magnetic
>field. The magnetic field can be influenced by ferous materials
>outside of the coax and can induce current in them. The copper or
>aluminum shield cannot contain the magnetic field. This is why it
>is recommended to route coax AWAY from conduit and water pipes
>through the house. This is also why coiling coax is a no-no. You
>concentrate the magnetic field and the coil becomes a choke.
>Especially in VHF and up.
