I'm proposing to build a new multi-band HF antenna. Previously I used simple
relatively low (8mtr) dipole (28mtr total length) feed with ladder line and
matched with a Z-Match tuner. Worked ok, but was useless for DX.
My proposed antenna is to be vertical (7mtr radiator) to be used on bands
from 10mtr to 30mtr.
I have heard that vertical antennas are more susceptible to noise!

I'm keen to hear this groups view on the noise issue and generally how
verticals are regarded as a DX antenna. Also keen to hear of personal
experiences with vertical antennas on HF.

I'm thinking of getting one of these for the roof:

That's my plan as the garage has a large surface area galvanized steel roof.

The Titan DX doesn't require a ground screen of any kind. It has a
built-in counterpoise, and is center-fed.

Are we talking counterpoise or are we talking load?

If you are talking, wipe off the screen. I trimmed Dave's post to
reduce confusion - your alternative word, load, never appears.

In fact, we never conjoin the term garage and load, nor roof and load,
nor power lines and load. No, counterpoise has a well known and long
established meaning that has been found in a lot of texts and none of
the authors have ever felt the necessity to join that term with
garage, roof, or power line either.

Perhaps Newton kept his counterpoise in his garage - the historical
record is rather vague on this matter.

History informs us he would have called it a condenser, your word came
into the language later from Le Compte a'Citor, Gauss's French Pen-Pal
from junior high.
