Perhaps the same "oil derricks" as were  used in 1958's "Touch of Evil", 
where the Venice district of Los Angeles (nominally, West L.A.) is 
substituting for Tijuana.

In those days, there were such structures in and around several parts of 
L.A.

Hell, Beverly Hills even had one, cleverly disguised, at the Fox Hills 
end of the city, on Olympic Blvd.

Self-supporters in W.L.A.:

1) 790 ... one, which is pretty short, in a DA with a tall guyed tower,

2) 930 ... two, 90 degrees each,

3) 1330 ... two, 200 degrees each.

If as early as 1953, then perhaps those structures were in South L.A.

The W.L.A. Division police station also had an MW police radio station, a 
roof-mounted self-supporter, near Purdue and Santa Monica.  It stood 
until the 1960s.
