Antenna Installations
We spend quite some time finding the "hot spots"
on the roof where the signal is the strongest, especially
in bad reception areas.
Antennae are installed with 38mm poles and 3 leg
brackets for solid mounting.
Brackets are galvanized the hot dip method and not
electroplated
All mounting is done on walls and not on wood.
Antenna cable is directed through holes in walls
and not through tiles (if possible). |
 |
The place for the best installation
point is determined by a field strength meter. The
best place isn’t always available due to the
shape of the roof. We try to avoid reflection signals
from nearby roof sheets. Any signal lost through
cabling and in poor reception areas is measured
and rectified through amplification.
The pole is mounted a correct distance from the
wall, so canceling out any knocking sounds in windy
weather. We don’t install antennas inside
the roof because it creates comeback situations.
We also feel that a normal installer can do the
job. Only galvanized antennae are used. Antennae
with flat reception characteristics are used to
make amplification possible if necessary.
When a signal is amplified for distributing, the
noise gets amplified as well, and gets closer to
the signal level. That’s why we strongly recommend
the Skywave antenna followed by the Marlin. These
antennas have a good signal to noise ratio which
makes them excellent choices for distributing points.

The normal signal strength for a good
antenna is approximately 70 db. If the signal drops
below 55 db we move into a bad reception area. To
rectify this problem we us a master head amplifier
to lift the signal strength back to normal. Unfortunaely
amplification has certain drawbacks. It amplifies
the ground noise and other magnetic waves as well.
This noise causes interference on DSTV, M-Net decoders
and video machines. Therefore we install noise filters
to clean up this noise. To avoid most hazels, engineers
believe that amplification in these cases must not
exceed 15 db. |

Distributing points to other viewing locations |
Signal is divided in such a way that
M-Net, DSTV, DVD, video, TV1, TV2, TV3 and ETV are
available on every set. Signal loss is measured
at every point and amplified accordingly, to keep
the picture standard for good viewing quality. Installation
of extra points requires signal splitters. Due to
loss of signal through bad splitters we only use
the best product. |
 |
Head end With Setback amp
Head end in 2nd picture is more labour intencive
and cost R300 excl. more
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.
Then we also lay our wires just beneath the roof
tiles – away from power cords and well protected.
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. |

Calibration of decoders and video machines for best
reception |
Because of the number of senders and
TV stations in our region, they cause interference
with video and decoder output channels. This causes
poor picture quality; therefore we measure all 57
UHF signals and choose the cleanest space for your
DSTV decoder and/or video machine. If required,
notch or low pass filters are used to accomplish
the task. |

Installation of Plasma screen R400.

Best products
We only install Space, Alcad and Skywave products
to ensure best reception and quality service.
This means that our prices are higher but the
product we deliver to the client is above standard.
All our antennae are aluminum and galvanized to
combat rust. Every component in the amplifiers
is screened separately to seal off magnetic interference
for best viewing quality.
F- Connector tabs are used for minimum signal
loss. RGU 6 satellite cable is used for all installations
for maximum signal strength. Cables are laid and
glued very neatly thus eliminating interference
with power supply cables.
Outside cable is laid under ground and through
PVC pipe if possible to external buildings. We
recommend new builders to first consult us, beforehand,
to ensure correct layout of pipes and to avoid
interference with AC power lines and lay out of
cables. Wires are laid neatly through plug covers
and glued neatly against wall. |
Terms and conditions
There are cheaper options but the installer will run the risk of loosing his accreditation certificate.
These quotations are only valid if all the piping is open and in order.
A key must be available for each apartment at all times so that installation is not affected, and if not adhered to, extra time and labour fees will be charged.
Enough space in conduit is required for the installation of at least two cables per apartment.
It might be necessary to install extra equipment for example brackets, amps or ducting which is not included in the quote and the customer can only be informed of these during/after installation.
Quotation is subjective to terms and conditions as stipulated on website www.mrdish.co.za
Mr Dish will not be held liable for any damage done to the client’s property due to the normal installation procedure.
The client will be held responsible for any injuries to workers on site caused by structural deficiencies of the building.
Payment to be made after completion of work.
All parts remain the property of Mr Dish until settled in full.
Hiring fee will be charged on all parts not paid within 30 days after completion of installation.
