Harry Huking, Regnar T. Freng, and J.H. Woodward are pictured at Oakland Airport in 1936, examining an antenna array being tested by United Air Lines (UAL) and Bendix Radio Corporation on a Boeing 247, as part of an experimental instrument landing system that was initially developed by the National Bureau of Standards (NBS). See: Innovation and the Development of Flight, by Roger D. Launius, Texas A&M University Press, 1999; Pages 91-92.

I think this is the center of a Kreco D-100 or D-150 discone antenna. Aluminum rods thread into the threaded holes to make a completed antenna. Your corrections are welcomed. example on eBay

Definitely the central mounting element of a discone antenna.

I tagged this as Chula Vista plant because that looks like San Diego Gas and Electric's South Bay Powerplant and it's bunker oil tanks in the background.

Could this be a feed for one of those jumbo Cassegrain antennas? Are the round things round wavegude couplers for different bands?
