WARNING Adrian is useless (but I support his right to post).

Satellite "antenna".

A yagi design is not viable for sat Ku band, since at that frequency
the elements are too small, and anyway you won't get enough gain, and
it would need to be impractically long, and then in any case you
couldn't have a 1Ghz bandwidth!

The LX200 is a "dielectric antenna", as commonly used in microwave
system. From reports, it isn't as good as a standard lnb with a 43cm
minidish, but is usable for Sky.

Does anyone know if this is simply a sausage shaped lump of plastic that's
solid all the way through, or is there more to it? Why is it tapered into a
teardrop shape at the end that points to the satellite? What shape is the
dielectric inside the tube, could it be conical pointing at the satellite,
conical pointing into the LNB, or would there be more than one seperate
section of dielectric? What sort of material is the dielectric? Does anyone
know any links to information about dielectric antennas for microwave? Would
it be possible to make my own dielectric rod antenna out of a suitably large
chunk of plastic, and just tape it to the front of an LNB, or does it need a
very precise shape and special materials?

My neighbour uses a bent No.5 knitting needle with great results.
He gets umpteen satelites, not just Sky.

Thank you very much! Just what I wanted.

Interestingly, though, it now refers simply to "antennas" and not to
"dishes". It says two "antennas" can be erected without planning
permission. I already have a fairly large DAB radio antenna in place,
as well as one satellite dish. I wonder if that will now count as the
statutory "two antennas" under the new rules. I need to wait for the
guidance booklet to come out and study it carefully.

Ha ... there is one very important word in the document. It refers to
all types of MICROWAVE antennas. So in the strict technical sense,
that excludes DAB broadcast antennas which work at VHF.

Try explaining that to the Local Planning Department, though!

i.e. -it hasn't changed yet
-it only applies to England.
-you'll be allowed one big(ger than present) aerial (up to
1000mm/35l) and one small(er than present) aerial (up to
600mm/35l); the larger dish would be up to 1300mm/35l on a
building over 15m high.
-it applies to any type of aerial, not just dishes (as IMU do the
current regs to some extent).

Naughty, Donald! You omitted to point out that the position of the bend
is critical. It must result in a dipole that's exactly half a wavelength
long. I'll be charitable and assume it was an honest mistake and not a
deliberate attempt to mislead people.

PS: I thought a No. 6 gave better results?

Sometimes I'm so glad I live in Spain! Three dishes (60cm, 1m &
1,2m) on the roof together with two terrestrial aerials, and a 2,4m
giant in the garden. Nobody bats an eyelid.

There have recently been some changes to planning regs re "antennas"
which don't seem to have been be drafted all that well.

Not my comments, but those of a local planning officer!......

So if you want a four or six element FM aerial and you haven't got a
chimney stack to plant it on then tough shit by the look of it then!....


two antennas will be permitted;
the size of the antennas will be restricted
the larger having a maximum of 100 cm in any linear direction and 35
litres cubic capacity by volume;
the smaller having a maximum of 60 cm and 35 litres cubic capacity by
volume;
chimney-mounted antennas will also restricted to a maximum of 60 cm and
35 litres cubic capacity by volume.
the antennas will have certain siting restrictions:

no antenna should protrude above the roof if the premises does not have
a protruding chimney;

if the premises has a protruding chimney, antennas may protrude up to 60
cm above the roof, or up to height of the chimney, whichever is the
lower.

In an obscure part of the document, it says it is referring only to
