Hi Simon (Mag)
Congratulations on new house. Not in any way wanting to put
dampener on, but just a plea to think about wildlife. Stringing
low wires across fields in open countryside, deer will get tangled
up at night. Slightly higher wires, birds will hit it, especially
owls when scanning field for rodents. If you think it does not
happen I have it on my own security cams, owl hitting my low slung
(and luckily very slack) wire. He (she?) was OK. If it had been
pulled tight I reckon high chance they would not have flown off so
happily. Even so, may have been injured of course. Not proud of
it. That wire has now gone. Now got much higher EFHW well above
usual "hunting owl height" but kept slack for the same reason.
I've got space to put out any number of wires on my own land but
as a wildlife lover I don't for exactly that reason, though of
course I know many do. Usual response is "I've never seen it
happen", but that doesn't mean it does not.
Sorry, still fuming from idiot walker crossing field this
afternoon with two stupid dogs off lead (sorry, that's perfectly
OK dogs with stupid owner) totally out of control, off footpath
and all over field chasing after previously peaceful grazing deer
who then get panicked to jump fence in awkward place. Now,
"where's me gun Rosemary......." (one for those in the UK old
enough to recognise the reference from classic TV series!).

Consider the probability of an owl connecting with a wire. What
is the intersection area for the likely owl orientations vs all
the other paths it could have taken. I suspect it is very small.
That suggests to me that there may be an owl overpopulation if the
owl/wire collision happens with any frequency. To me that suggests
this is something to see as lamentable but not something to get
worked up about.
With regards to the analysis I wonder if a tight copper-weld wire
would be better than a slack wire. The slack wire's curve would
make a collision more likely near the wire ends or mid-supports.
As for deer interactions - the deer ate your rosemary.
