OK guys,
thanks for all the replies.

My main reason for asking about this type of aerial is that in a month
or so I have a job for a few days in the Highlands of Scotland, miles
from the nearest road and even further from habitation. This location
should be nice and quiet for HF and has a very wet ground surface so
should provide a reasonable earth. Also, and this is the good part, I
will have a 100' trailer mast with me that only has a VHF collinear on
top, this mast is just asking to have an HF aerial attached to it !!.
Unfortunately once it is up in the air I don't think my customer would
appreciate me raising and lowering it to tweak the HF aerial, hence
looking for something broad band and pretty much "plug and play".

My original intention had been to make something similar but thanks to
Chris G4BOH's offer I shall be using his aerial on the day.

all made for interesting reading. Ranging from "rubbish" to "
brilliant" so we shall see. :-)

W4RNL's site managed to use up quite a few hours of my day yesterday,
certainly made a good read, it is now well and truly book marked on my
PC, thank you.
