I found this wire sculpture that I painted red and white to serve as a radio tower in my O gauge layout! 
Hey Eugene!
Put some Microwave antennaes on it! A automatic cell tower!
Also an option!
Oil well!
Or…atomic bomb test site!
Many possibilities!
Needs a flashing LED on top
Or a rotating beacon!
How about a rotating radar dish?
Hey Eugene!
The radar? You could use the 1/200 P.E. dish from the Missouri or any Iowa Class.
Or the one from the U.S.S. North Carolina!
Yes if I could find them!
Bill
That could work quite well!
