Installations of
Multi Unit Dwelling Systems (MUDS) for flats or
Hospitals |
These Installations are quite complex and require
a lot of skill and knowledge to be sorted out properly.
Therefore we want to mention a few pitfalls and
explain how to overcome it.
Location
The head end of an installation is where all the
wires decoders, video machine and DVD come together,
being processed for distribution.
It is normally located near the reception area for
easy access. Try to locate the best area for the
head end. Please discuss location with installer
during building stage and plan before hand for correct
layout of ducting, grids and wiring Moving a head
end at a later stage is costly and time consuming.
Head end can look like this: |
 |
| Broadband Amplifiers,
Tab’s and Modulators for decoders. (Hotel
installation) |
 |
| Decoder cabinet |
Modulators |
|
| These systems require a lot of cable,
which means that an enormous amount of wire aerea
is expose to magnetic fields. Power cables in roof
and building generates strong magnetic fields and
the TV cable or coaxial cable absorbs this energy.
This absorption of magnetic field is called magnetic
induction and cause interference on TV screens or
can stall DSTV decoders.
To solve this problem we use coaxial cable with
a screening factor of more than 49%.
Secondly we lay the antenna cable in the middle
of the DSTV cables and thus use the other cables
as an extra screen if possible.
Then we also lay our wires just beneath the rooftiles
– away from power cords and well protected. |
 |
| Here you can see that the wires are
laid away from power cables to avoid magnetic induction.
Secondly no one can stand on it which means no kinks
in the cable. Kinks in the cable cause percentage
blockage of signal and redirect part of the signal
in the opposite direction, which causes interference
on TV screens. |
 |
| |
| These problems can not be rectified
through amplification because this will amplified
the interference or the distorted signal as well. |

machines and decoders |
|
 |
| Launch Amp with broadband Tabs |
TV’s do have a tendency of sending
noise back into the antenna cable. This signal in
the opposite direction will cause interference on
TV screens.
With multiple distribution points this can become
a big problem. Therefore we use tabs and not splitters
because they block this noise and prevent it from
going through to the rest of the system.
This method of wire installation is prescribed by
SATRA (South African Television and Radio Association)
as well as Stellenbosch University. As far as we
know Mr. Dish is the only company that follows these
rules to the end.
|
People sometimes
ask, what is the difference between a Mr Dish
installation and the guy next door.
- Our installations are technically correct
and obey the laws of physics and science.
- We spend a lot of time laying our wires
away from power cords.
- Our cables are laid in the roof in
such a way that no one can stand on it,
preventing it from getting kinks that
causes reflection signal in the cable
which lead to poor reception over a period
of time.
- We use genuine copper cable and not
copper clad which disintegrate with DC
over a period of time (+ - 14 months)
- We refuse to install parts that have
caused us trouble in the past. We give
a 1 year guarantee on installation and
cant afford comebacks due to sub-standard
parts

The Alcad broadband system is presently
Europe’s nr. 1 choice for hotels and apartment
blocks.
We have found that certain TV’s respond much
better than others. We therefore recommend the Panasonic
and Sansui TV’s. Sansui TV’s are manufactured
in the Western Cape and the electronic functions
can be modified during manufacturing to suit Hotel
and Hospital conditions. Special remote controls
are optionally available that restrict public access
to the set-up menus. This means that the TV’s
can be tuned in with a normal Sansui remote, and
will then be substitute with a remote of which only
the Volume, Channel, and On Off buttons work. This
means that nobody can wipeout or retune the TV.
The same alterations will be made to the buttons
on the TV itself. Sansui uses a cheaper Toshiba
integrated chipset than other TV’s but react
much better to the system than some more expensive
TV’s. According to Brain Coode of Sansui the
reason for this phenomenon is unknown. Older TV’s
like the Goldstar also react good. |
