From the left is a Butternut 80/40 vertical then an Imax 2000 (CB antenna)
for 10, 12, 15 and also mounted on the back porch a Diamond V2000 for
6, 2, 440. then on the roof is a discone plus some UHF WX transponders.
In addition to Cox and Ma Bell were 4kv, 12kv distribution feeders,
and above that a 138kv tie line (not visible in pic). All of that wire either
radiated its own noise or parasitically re-radiated noise of the others
so it was often, but not always, difficult to get a precise source to use in the
phase noise canceler (ANC-4).
The TV antenna was useful to get OTA LA stations like KCAL9,
SoCal's premier car chase station. g
