How can a TR165 coaxial cable be used with a saddle and clamp connecting device?
A TR165 coaxial cable can be used in this way by employing an adapter lead as indicated below:
Splitband amplifiers have a maximum output level that is similar to broadband amplifiers, so:
What are their advantages?
-->Splitband amplifiers feature two separate amplification stages (as their name indicates).
Each one is tuned for the UHF and the VHF bands.
Because of this, when applying a reduction of the maximum output level, the UHF and VHF channels have to be considered independently as if they were two broadband amplifiers.
Therefore, for a particular number of VHF and UHF channels, we can achieve higher output levels using splitband amplification rather than using broadband amplifiers.
What is the bending radius of a coaxial cable?
In a satellite TV installation, most of the satellite channels are not received correctly except those that I know are received with a high power level.
The LNBs have to be installed with a certain skew to obtain the correct polarity discrimination.
Usually, when a dish is orientated towards a satellite positioned to the east, its cable comes out from the left-hand side (when looking at the dish from the front)
When the dish is oriented towards a satellite positioned to the west, its cable comes out from the right-hand side.
The internal sensors of the new LNB, ref. 7475, are inverted.
Because of this, to receive satellites positioned to the east, the cable comes out slightly sloped to the right.
As well as this, it is always necessary to carry out a polarity discrimination adjustment, using a Field Strength Meter.
In a domestic analogue and digital satellite TV reception system:
What should I do?
There are digital receivers that are continuously sending a 22 KHz tone to the LNB.
This way, the LNB is always receiving the high band of the satellite.
To disable this tone, you must:
I have a SAT92 installation and I think its power supply unit could be damaged.
What are the voltages and what is their location in the connector?
I have refs. 5054 and 5078 installed but I can see horizontal lines moving vertically across the TV screen.
What should I do?
The effect of the horizontal lines moving vertically up or down the TV screen could be because you have installed a T05 headend unit without taking into account that the mounting must have the same grounding reference point.
To avoid this, you must install the equipment:
Can the CDC control module (Headend Management System) be connected to a LAN and be controlled from it?
The Headend Management System software does not have the protocol to be able to work within a LAN network. So the answer is no.
How can I arrange the channel amplifiers units in the headend to combine adjacent channels?
