This is something that Spike has recommended, so perhaps a
couple of loops at the bottom of the garden well away from
the noise-inducing consumer electronics in this row of houses.

When I, with the right moral fibre to get something that
I wanted, took the Morse test at Portishead (Highbridge)
Radio in 1983, and then had a guided tour of the station,
the operators had a 32-position rotary switch to select
one of many receiving aerials pointed to all corners
of the globe.

I wonder if these would have been Wullenwebers / Elephant Cages,
or somewhere a field of rhombics.

What's the recommendation for remote RX antennae, loops or a single whip?

I prefer 14 element yagi's.

We don't have the open prairie as in Yankland. Here in Britland all
land is owned by somebody and usually parcelled out in small lots,
about the size of a Yank double garage.

Actually in Brit, all land is owned by the cancer of the crown and
those who think that they are homeowners only hold the property
"in fee simple".

Not sure what all the babble about land in the UK is about since a 14
element yagi is 5 meters long.

Eh?

Even on Portishead Radio's highest frequency channels (around 25MHz), a 14 element Yagi would be about 30 metres long, assuming 0.2 lambda element spacing.

No entirely correct.
This applies under English law only so applies only to England (and
probably Wales) and not to the whole of 'Brit'; Scotland and NI have
their own legal systems.
Scotland abolished all feu duty and feudal tenure (Scottish equivalent
of fee). NI used to have a similar system called 'Udal' but that has
been abolished.

Probably a loop, but you've given us no clue as to what sort/size of
waves you are hoping to catch. So, wibble/flip.

Y'er welcome. However all is not lost. If you search for "Antennas
made from junk", there are a few that look like they might meet your
cost and construction requirements:
<https://www.google.com/search?q=antennas+made+from+junk>
Please note that it is not necessary to start with junk in order to
produce an antenna that might be declared to be junk. This is not
really a bad thing, as it is well known that ugly antennas work best,
and that nicely constructed antennas rarely work without the addition
of decorative junk.

You've considered Wellbrook or Cross Country Wireless loops then?
Probably 1/10th of the cost of DX Engineering. Otherwise home-brew take
a look at the G8JNJ design.

Never heard of either company, but what they're offering is what I had
in mind.

ISTR coming across such a published design at one time or another which
is what triggered my OP.

I had in mind two such antennae mounted orthogonally, powered via
the coax cable with a remote controlled goniometer, the PSU for
all to also be pulsed at 1 - 2 mSecs for the servo to drive
the goniometer.

A Jait of that vintage has neither experience of, or business on, HF.
Any Jait of the right moral fibre and worth his salt had plenty
of time to pass the 12WPM Morse test even if
never intending to use the mode.

This is something that Spike has recommended, so perhaps a
couple of loops at the bottom of the garden well away from
the noise-inducing consumer electronics in this row of houses.
When I, with the right moral fibre to get something that
I wanted, took the Morse test at Portishead (Highbridge)
Radio in 1983, and then had a guided tour of the station,
the operators had a 32-position rotary switch to select
one of many receiving aerials pointed to all corners
of the globe.
I wonder if these would have been Wullenwebers / Elephant Cages,
or somewhere a field of rhombics.
What's the recommendation for remote RX antennae, loops or a single whip?
Why a whip?
Why not something fully directional?
Since you are a pi fan like me have a look on google for a pi controlled
direction antenna. Many use old astronomy mounts and while these are
actually for telescopes they also work for a well-balanced yagi or
similar. My wife is an astronomer and has a number of steerable
telescopes I do the building of the computer interface for her.
You can pick up old rs232 controlled mounts cheaply on gumtree.

https://www.raspberrypi.org/blog/controlling-telescopes-with-raspberry-pi-and-mathematica/

https://www.mups.co.uk/project/software/astrocat/

There are a number of papers in the IEEE Antenna and Propagation Society
library on using a pi to control directional antennas, if you are member
of the IEEE or qualifying society then you will have free access.

Sadly as a coeliac I cannot have pies to my great regret, the 'glutard
friendly' pies they sell in the shops are a bit rubbish and worse than
no pies at all.
20 years on and I still dream of a proper Melton Mobray pork pie.

I think the implication of Gareth's post was that he was considering HF,
so a az-el mount is a bit academic.
