I should make a good wire antenna, have an antenna tuner,
but so many other projects.

From the photograph you linked to, showing your garden, it looks as
though you are hemmed-in on all sides by houses.  A long wire might
work, but it also could act as a conduit for noise picked up from your
neighbour at the distant end.  You need to keep it as high as you can
without attracting the attention of the local authorities.

Long lightweight alloy poles are sold for television aerials and one of
those can be fixed to the shed or a fence post without needing guy
ropes. as long as the wire isn't too tight.  You can buy the plastic
equivalent of 'egg' insulators or just use a length of monofilament
nylon fishing line.  With an ATU, the length isn't so critical.

The biggest problem is usually the lead-in.  I managed to bring mine
into the loft in the gap between two tiles and then used co-ax to
connect it to the receiver.  There is a mis-match at the aerial end, but
the downlead matches the receiver input impedance, so the downlead
doesn't form part of the aerial and doesn't pick up interference inside
the house.


There is a project on the web that subtracts local RF noise from the
antenna signal

There were plans published for some of these in The Netherlands during
WWII under the name "Moffenzeef".
