Throught The Roof Satellite
Systems 
The "through the roof"
system is quite different from the "crank up". Although they
both require a hole to be drilled in the roof of the Caravan,
the "through the roof" system has an additional pole. This pole
drops down from the bottom of the dish and is ideal for
location in a cupboard.
This may not seem much
of a difference, but it means that this unit can only be
fitted "to something".
By that we mean the poll has to be secured
to a wall or inside a cupboard.
This type of satellite
system is considered to be the best suited for caravan use as
it puts very little stress on the roof.
Alden "Through The Roof" system.
Also known as the Alden Gosat Confort.
This unit can have
either a 65 or 85 cm offset
dish fitted and is classed as
a semi-automatic system
as the elevation is done by pressing a button, rather
that using a crank.
 |
The Alden Gosat Confort
features a LCD display
in the base of the unit with a digital
readout of the elevation of the dish. The
dish also remembers the last
elevation.
The unit comes with an
elevation guide
that gives you the rough elevation for the
country you are in.
You will
also require a sat-finder with this unit to
locate the satellite once the elevation has
been set.
The unit
folds down to 19cm and has a weight of only 4.5
kg's.
The 65
cm dish requires 140 cm's of roof space when
folded down and the 85 cm dish requires 180
cm's.

Globesat
Not to be confused
with the above system, this unit is not Alden. We
couldn't establish the manufacturer of the unit. The main UK
retailer for this unit is RoadPro Limited. However several
other sites did advertise it.
This is also a "through
the roof" system but does not have power elevation. The unit
uses a crude slider to elevate the dish. It is quite hard
to get the hang of an is very sensitive.
The dish is
57cm but claims to perform like an 80cm dish. We
have confirmed that this seems to be correct due to the
technology it uses. This unit has a
Cassegraine dish or
reflector.

This is not
manufactured by Alden.
The Globesat has a un-screw
and slide type mechanism to raise and lower the
dish. This in turn pivots the dish on its base.
see photo The unit has a scale
on the handle to set the elevation.
This
dish also requires a sat-finder to
acquire
the satellite.
The unit folds down to 28cm's which is
quite high is hight is an issue.
However
the dish only requires 57 cm's of space on the
roof and the pole can be pushed
high to avoid any obstructions on the roof.

Omnisat Semitronic Satellite System
This unit has an 80cm WIDE elliptical offset dish. This is simular to
the dish that SKY uses on your house.
  |
The Maxview Semitronic is
another semi-automatic
satellite system with last
elevation memory.
The unit features a seperate LCD display with elevation
readout.
This
unit requires a sat-finder to locate the
satellite.
The unit
folds down flat for travelling to 21 cm's. The
requires roof space is not given on the Maxview
website.
This
init weighs 11.6 Kg's.
Maxview have a link to the
fitting instructions.

Well that would seem to be the lot.
However if you know of any other fitted manual caravan
satellite system then please put a comment on our blog pages.
WWW.satsig.net This is a great
website for calculation the elevation and azimuth for setting up your
dish. (Azimuth is direction.)
Fitted to something refers to the
fact that the unit has a nolder for the pole that drops down
from the base of the system. This must be securely anchored to
a surface.
