On a recent visit to a Coast Guard station, I noticed a strange (to
me) member of their antenna farm.

It was mounted atop a 20-25ft un-guyed mast, and appeared to be
constructed of three half-loops, each approximately two feet in
diameter, and each in a vertical plane 120 degrees from its neighbors,
all joined together.

It sort of looked like an egg-beater on a broom handle.


If further clarification is required, imagine three letter 'C' shapes
of equal size, all joined at their open ends, and standing uniformly
spaced so as to appear from above as a 'Y' shape.



Well, it looks like my guess was correct, based upon this TCI antenna
data sheet:

(The one I saw was only about one meter or so for each loop.)


Good listening,
