Can conventional SMATV splitters be used to distribute signals to different TV transmitter modules?
This may be possible if the signal has a sufficiently high quality (a good C/N and an adequate input level).
The use of conventional splitters implies impedance mismatching which produces signal loss.
This is because the impedance of the splitters is 75 ohms and the impedance in professional systems (both in boards or in active equipment) is 50 ohms.
To solve this problem, you should use receiving systems of 50 ohms (professional antennas), as well as cable and splitters with the same impedance.
I have a mobile SAT TV installation consisting of a receiver and a positioner ref. 7320, but suddenly the channels just disappear. Why?
When something like this happens, it could be due to a power failure while the dish was rotating (and when the positioner was working).
To retrieve the lost channels, press the following combination of buttons:
“Full HD” and “HD Ready” televisions vs High Definition DTT
In an agile modem installation, some of the channels present saturation symptoms. Why?
Agile modems feature a little active stage in their input.
There is a possible risk of saturation as in any amplifier.
This depends not only on the channel level but also on the number of channels being amplified.
To avoid this saturation, the input signals should be equalised.
I have two dishes installed, using a single downlead via the pulse switch ref. 7431.
When I change the channel within one satellite using the "step through programmes" button , sometimes the dish being used switches over to the other one.
Is there any way to avoid this?
The change of dish is caused by the fast change between channels with different polarities within the same satellite.
A good solution is to programme channels with the same polarity and from the same satellite consecutively.
This way, you are avoiding the fast change of polarities that causes this switching of dishes.
To change satellites it is necessary to programme any two even channels with no content.
This programming will cause the necessary polarity change so that the switch, ref. 7431, changes input, going quickly from one channel to another:
I have a problem mounting a 1046 PRO75 antenna.
Using the two clips provided, the only way seems to be to clamp the pole to the bottom support that goes from the front plastic piece to the back reflectors and the middle of the three directors.
This means that the 50 mm pole goes up and half way through the three directors, with a metal clamp.
The illustration on your website under "other pictures" shows the antenna mounted to the bottom support only.
How am I supposed to mount it?
The way to mount the clamps of the antenna is as follows:
Ref. 5079 has been locked and I cannot remember the code to unlock it.
What should I do?
The tuning in the SAT100 unit for high frequency channels (like Sky News) is OK and there are no sparklies on the TV screen.
However, once these parameters are stored and the programmer is unplugged, some sparklies appear.
It seems that, when the AFC starts to work, the picture becomes worse instead of remaining the same.
This can happen if the discrimination between the vertical and horizontal polarities is not good, since there are interferences between adjacent transponders.
I have a satellite receiver TELEVES RSD 7254 [(SILVER LINE) (Motherboard inside EMTEch-EM200-Rev 1.20)].The customer,who brought me this receiver,has locked the installation menu and lost the code.How can I unlock the receiver?
Please follow these steps:
The T93 series or plug-in series of converters allow the conversion from UHF channels only to all the other bands.
What should I do to convert from VHF to VHF channels?
We recommend the use of agile processors.
An agile processor is a universal channel converter.
They can accept any input channel from any band while the output channel is limited by the reference being used:
Depending on your needs, there are other alternatives:
