Either he's wanting to verify the true omni staus of the vertical by
experimentation or (more likely) he's installed a quickie vertical in place
of a busted beam, while he rebuilds the beam. Do you know the fellow well
enough to ask, so we can know for sure which it is?

I would guess the latter.

Back in the 70's I saw a CB beam mounted with the boom in the rotor pointing
straight up. I guess he didn't want the mast to the rotor interfering with
the vertical yagi.

A few options here...

- NVIS.or short skip distance use only. A 3 element yagi has what, a 120
degree lobe? I did some experiments a long time ago with a quad on 27MHz
with it pointed up at about 60 degrees. Stations about 300km away were
real good but almost no locals. Have to be a very good ionospheric day
of course.

- Speaking to ET's (of course)

- The whole thing was fed as a phased array or the lengths of the Di/Re
were varied to give a broadside pattern. (Or an experiment with same)

- There were some low flying but stupid Galas in the area (pink & grey
parrots) that along with chewing coax also had a very set flight plan
that the operator was trying to dodge..

One of the funniest things I saw was the expectation that a yagi mounted
real close to the ground or roof was actually going to perform well..
A good example of this is one mounted 6-12" above a rotary clothes line.

Might not be what it looks like.
