thank you all for your prompt replies! in answer to a couple of you the
electric circuits are completely seperate making homeplug inoperable. I
would like if possible to keep a physical data link as ive had bad
experiences with wireless reliability, plus using cat5 i can go up to
gigabit if needs be.

As with the comments above everyone seems to have conflicting views on
whether its a good idea to link buildings. Im not interested in using
fibre as its WAY too expensive for this project. A cheapo £20 switch
will be at either end of the line so im not too bothered if the risk of
it blowing is there, as long as it isnt a common occurance!

I'm torn as i would like to try it but dont want to do anything
dangerous in any way. The building is being done up and will have an
office in the end of it that requires internet access as well as
reasonable transfer speed for backup purposes.

thank you for your comments

Have you looked at including one (or two) of these?

They would need to be installed with a serious earth spike each to be any
use, but that's basically only a metal rod into the ground. That would
make it absolutely safe.

When I did the same thing (from a stable block office to a farmhouse) I
just ran outdoor spec Cat-5 in a buried PVC pipe then had a cheap switch
each end, away from anything flammable... sound familiar?

would plugging each end into a surge protector with an ethernet port
have a similar effect? or a UPS? also both buildings run off the same
transformer and are about 10m away from each other - surely it
shouldnt be this hard to link them

I find this statement difficult to reconcile with your earlier one
that, "The route i would like to take requires digging a trench and
the total cable distance comes to about 70m inluding going around
walls etc."

Is there really no way of doing a shorter run, even if it means
digging up some concrete or going under a wall? A lot of the
problems people have mentioned become less as the distance between
buildings reduces.

the majority of the distance is inside - the two switches are at the
furthest end away from each other of each building (does that make
sense?!).

I see. In that case it may make sense to adopt a mixed solution,
with internal cables going to the walls nearest to the other
building and something else to bridge the gap.

What does the gap consist of? How easy would it be to dig something
under the ground? Are there any obstructions to a radio link using
directional aerials?

How easy would it be to run a data cable through each building,
perhaps in a loft?

It isn't hard. Four ways of doing so have been offered; radio,
fibre, internal grade twisted pair protected by a duct and outdoor
grade twisted pair. There are others but one of those four should be
suitable and all should work. All have their particular strengths
and weaknesses, which the sensible have put forward arguments for
and against.

It is up to you to consider all this information/opinion and decide
for yourself. Only you know the two buildings.

I know how I have linked two buildings 10m apart (and it is not the
way some of the usual suspects may imagine), but I may have come to
a different solution if looking at your two buildings.

At the moment, it's swallows here. They seem to love garages and hate

At least the local 'super-territorial' male blue-tit seeoms to be

For a couple of months he was hanging onto the car doors and headbutting
the rear-view mirrors - and, judging by the evidence he left behind,
getting very, very upset !
