[TowerTalk] Pneumatic Mast

[Stan or Patricia Griffiths]

Hi Bob,

You might consider contacting your local TV Station with a portable video link
in a news truck.  They typically use a pneumatic mast for their link antenna and
I think the go about 30 feet or so.  You might find out where they get theirs
from.
