No, General Electric.

When you lift an aerial (by pushing the mast up through the brackets)
to roof screening effects don't stop 'just like that'. Funny innit?

Rather than being a screening effect, could it actually be due to
destructive interference from signal bouncing off the roof?

that can happen, too. But remember that many roofs have a substantial
metal content (red concrete tiles are coated with iron oxide) which lifts
the local earth plane to roof top level.

I don`t care if its not the most perfect job that could ever be done.

That's what's wrong with this country.

There was a programme on a month or so back about Rolls Royce making
turbofan engines, one thing that came across was how *everyone*
interviewed was very proud of the job they do (or did) and was concerned
to do it right.

No that's wrong. If you are given a job to do you owe it to yourself
to do it to the best of your ability. Even if you are a student doing
a menial job during the holidays you should do it properly. If this
was drilled into kids at school things would be a lot better.

That's another way of conceptualising fresnel effects. There are
refractive as well as reflective effects involved. The simplest thing
is, don't have something near the signal path.

Yes, if the roof is near the aerial. Yagis don't like a ground plane
within a couple of wavelengths. This used to be an issue in the days
of VP 45MHz transmissions. You could get low gain problems when you
were doing an aerial on a backyard pole (for a prefab or caravan).

Another thing is that any internal wiring can be almost where the
aerial is looking, potentially bad when the roof is made of flimsy
stuff like shingles.

Slightly off the subject, you can get massive problems when the aerial
is just above a flat roof and looking over it, when the tx is
significantly high up. You get nulls and peaks as you move the aerial
up and down the mast. It's because of shallow angle reflections from
the roof. I had one of these once where standing water on the roof
caused almost complete loss of all channels.

I should imagine a lot depends on whether you like the job or not, I suppose
you love your job that`s why you put in the extra effort that others can`t
be bothered to.

The attitude of the installers maybe but I`m ok with it as long as it works
properly, if for some reason because of their cack handed installation the
system does not function as it should then I will be the first to complain.
I don`t care if the FM aerial is ****e or even if the freeview reception is
crap, all I`m really interested in is the satellite reception of Sky.
