They are generally vertically oriented, therefore the 'inverted vee'

I think characterising the Inverted V as an ''inferior'' choice is
wrong.

Damn, you finally got something right.

Huh? Please describe what you mean by a "horizontal inverted-vee" v.s. a
"vertical oriented inverted-vee" Dr. Arnaud clearly described an
inverted-vee where the house forms the center feedpoint and the ends are
lower at opposite ends of his property. This is like every other
inverted-vee I ever heard of, whether center point was a tower or any other
kind of support. Just because the ends slope downward (giving some vertical
component to the antenna) does not make it a vertical-oriented antenna. It
is not. It does have less directionality because of it's vertical component,
and slightly wider bandwidth than a pure horizontal half wave dipole. It is
also less efficient.

No, actually it has less bandwidth. Look it up!

also less efficient.

You get back to me after you go to 'antenna school'! And, after you finally
figure out the difference between 'horizontal' and 'vertical'.

I don't think I ever really mentioned a 'horizontal inverted vee'...

You really need to pick up an antenna book or two and actually go out and build
some stuff.

Please, go back and read the original posters comments and actually try to
envision what he was proposing, which would seem to be a 'horizontal vee'.

At any rate, using an 'inverted vee', or a 'horizontal vee' dipole antenna for
general shortwave listening is simply a bad idea.

Your inexperience is certainly showing this morning, Jack.

Steve,

Here are your exact words to Dr. Artaud:

"An inverted 'V' itself would be vertical... a horizontal 'V' I think is
what you
envision."

Now as I tried to kindly point out before, you are mistaken in calling that
horizontal as compared to some imaginary and "normally vertical
inverted-vee". Of course it's horizontal, and my question to you was "what
other kind is there"? Which you have failed to answer. I'm still waiting to
hear about this vertical-inverted-vee you're touting. I've been to some
antenna schools, and I guess I missed the day they covered your
vertical-inverted-vee.

Jack

nouthing!

Dr, Artaud,
.
You are interested in installing a 'shallow' Inverted
"V" Antenna that would be center over your House; and
you want to improve your Lightning Protection at the
same time.
(Snip)

RHF - I don't recall Dr. Artaud's particular circumstance, but here is mine:
My radio table faces an inside wall. The widow is across the room. Under
the window is a long concrete patio. So I can't have an earth ground
nearby. I can put up an antenna as you describe. My question: Is it safe
to disconnect the antenna input (center of coax) from the radio and switch
it to the household AC ground for lightning protection?

Greg

I told y'all before Greg doesn't know ****.There are such things as
drill bits made for drilling through concrete.(I own several different
sizes of them) Drill a hole through the concrete patio and then hammer a
six foot long ground rod down into the ground.

Lightning doesn't start at the top and travel down.Lightning starts at
the bottom and travels up.
