Does this look like an IRS Aerial/Satellite

No, Fremont remains HP after DSO. However it can't be pointing towards
Fremont, can it ? look at the relative direction compared to the sat dish,
against the other pictures.

If it's in St Helier, then there's a VP relay strapped to the power
station chimney, my money is on that ? If not then it's on St Brelades.

All three masts are in St Helier. Mast 1 and 2 are not pointing towards the
power station that is in the other direction and these are the horizontally
polarized ones aren`t they.

Mast 3 could be pointing towards the Power Station and it is also vertically
polarized.

Probably installed by cowboys, no doubt the cheapest quote.

I have no confirmation either verbal or otherwise that these masts are part
of the Digital TV upgrade contract tendered by the States of Jersey but it
is looking almost 100% certain that they are.

They have all the components of an IRS mast(s): Aerial, FM Aerial and
Satellite dish and they have only been erected in the last few weeks (why
else would someone suddenly erect three of these things) the only conclusion
is that this is phase one of the upgrade and I cannot really find any other
explanation as to their presence, after all they look for all intent and
purposes like communal aerials.

Do you think these are likely to be the ones used to provide freeview and
freesat/sky to the residents of the estate? All the other ones scattered
around are only satellite dishes and appear to be attached to particular
flats.

The FM aerial is crap, it doesn't look to me like a very professional job.

I was going to post about those myself actually - many new developments in and
around Manchester have been appearing with the very same aerial stack as that
photographed by the OP, so it appears to be some sort of building standard
(formal or otherwise).

I experimented with one of these "round" FM aerials about 10 years ago, and
found that reception was actually better when it wasn't even connected, and the
coax was left as the only thing picking up the signal. They're utterly useless.

jamie.

Just went to the Supermarket and noticed there is a 3rd Aerial/Satellite
installation on the building across the road similar the the ones
photographed above, these have all recently appeared as they weren`t
there a couple of weeks ago otherwise I would have noticed.

This is the 3rd Mast http://user.itl.net/~nlel/3rdaerial.JPG and this is
the 2nd Mast from a different angle

I've just noticed that the VP installation isn't on T&K or tripod brackets,
but is on a single wall mount. Simply ridiculous, the leverage will be
incredible.

Not totally, here is a Google street view of our communal aerial
system.

http://goo.gl/Zh4W

The top TV aerial is aimed at Sandy Heath, the lower one points at
Waltham.
Next down is a horrid halo for FM, followed by a vertical DAB dipole
then the ubiquitous wok. This is a standard installation at all the
sheltered complexes round here.

Here's a Google map of what the halo pulls in.

Not too bad. But it gets this performance by huge amplification, the
local relay of BBC Northampton stamps all over everything for 0.70Mhz
either side of its frequency of 103.6.

I can get comparable performance for local transmitters on DAB and FM
with a couple of internal half wave dipoles made from stripped coax,
shown in 3rd pic down on here. http://unsteadyken.posterous.com/
Luckily that windows faces towards the main Peterborough FM transmitter
which is 16 miles away over open country.

The installer has to take into consideration that he is feeding radio
to 40 flats who may want to listen to radio stations from any direction
of the compass. A better solution would probably be a vertical dipole
for FM.

I've also seen 3 of these identical installations on flats recently in
Evesham including the Infinito aerials, but with the addition of a DAB
aerial.
On other installations, the halo FM aerials seem to be giving way to an
almost Z shaped FM aerial which presumably is better with a VP transmission.

What a dreadful job, looks like at least a 60cm dish which will have quite
tight beamwidth, with all that above it flapping around in a strong wind
pushing the pole back and forth the signal from that dish is going to be
all over place.

Very much so.

A Discone with wide bandwidth distribution would do for DAB too

It's quite neatly done (see the way the cable have been taped up), but
it doesn't seem a very good idea to me for the dish and aerial to share
one mast. The tube looks a bit thin for that.

Nowhere near as bad as this:-

No doubt that was a so called 'professional job' too. Still, if people
go for the cheapest possible quote they're liable to be ripped off.
