[TowerTalk] Dumbing down?

[Bill Aycock]

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.
