Hi all

With a bit of luck I'm finally going to get my HF doublet up in the
air in the next week or so. I'm planing on about 150ft per top 'leg',
and will need a couple of hundred feet of open-wire feeder (going to
try heavy-duty 'slotted' ribbon for starters) .

Here's the question...
Due to the geography of the site, the shack is pretty well in line
with the antenna - which will be at about 20ft above ground on 3
poles. The site slopes, so that the eaves of the shack are about level
with the bottom of the nearest pole. In all the books, diagrams show
the feeder joining onto the 'aerial' at right angles - but I'm
wondering how best ot compromise on this in my situation.

Would it be better to take the ribbon feeder straight to the bottom
of the first pole & then run it underneath & in line with the aerial
(say a couple of feet off the ground) until it meets the centre pole -
then run it up to the feedpoint ......- or would it be any better to
run the feeder at low-level but parallel with the aerial (could be
about 20-30 ft apart) and then make a right-angled turn up to the
feedpoint...?

Possibly, in terms of the wavelengths involved it'll make little
difference - and I'm quite prepared to try it & see.. but I just
wondered what opinions / experiences group members could share.

I'm planning on the doublet to make the best use of the space
available, and to reduce the possibility of TVI (we're in a weak TV
signal area and effective earths for a long-wire aren't easy because
we have very dry, sandy soil).

Thanks in advance for any suggestions / comments
