When I'm walking my dog sometimes I'm watching the landscape and the houses. I noticed that several new antennas from Sky were with a different LNB, with a red tip. Researching the subject I found out that the Sky has been using this new LNB in new installations and also comes by replacing the old clients LNB in technical visits. Now they're putting this Broadband Dual Lnb, the Telesystem or WNC.
As a subscriber of Sky for more than 15 years, I still remember that the first was a Universal single LNB, with a single output. Was replaced by a Universal double when passed to a plan with two points. At the time I asked the technician what it would be like if I had more points and he explained that there were up to LNBs 4 outputs, but the Sky wore only the doubles and were more than two points using dividers.
I noticed that the Sky has also been using an LNB STO Red. This has the advantage of sending both channels polarizations (horizontal and vertical) using the same cable (all frequencies together). It's good for HDTV facilities Plus where you cannot pass a second cable, because simply put a splitter by the decoder to feed both tuners with the same cable. Furthermore, the signal can be divided easily to various points with simple high-frequency dividers, dispensing Switch 3×4 I showed in the previous article.
But now I hear the Sky also stopped with the LNB STO and is making the new facility only with the Broadband Dual Lnb. On the one hand, is a disadvantage, for he is like the Universal, having two outputs that polarized, and send the signal of vertical or horizontal channels, but not both at the same time, so the Sky Plus HDTV back need two cables. Furthermore, in installations with 3 or more points (or 2 points being at least one HDTV Plus) You must use the Switch 3×4.
The reason for the change, It is speculated to be the new satellite that Sky should throw even in 2016. The Intelsat 32e (Is-32e) should be called Sky Brazil-1 and will be used exclusively by Sky. Would 81 transponders in the KA and Ku bands. In Ku-band Sky could use up to 60 transponders, sufficient capacity to bring 3D channels or with 4 k resolution, for example. The Broadband Dual Lnb It covers a larger quantity of frequencies and, therefore, I'd be ready for the new satellite.
On my installation, the technician replaced the old universal Dual LNB for the Broadband Dual Lnb to install HDTV Plus point, What also made necessary the passage of new cables and the installation of Switch 3×4.
It is clear that Sky should not use additional frequencies until you change the LNB of the entire installed base. Possibly will leave these frequencies for new channels and go doing the Exchange as package changes occur.
Remember that a change of such proportions has already occurred in the past, not with relation to the LNB, but with respect to the access cards. On the occasion, the Sky needed to change the encryption used, that had been broken. The solution found was to update the base gradually, first for those who had the Premiere football packages, After Telecine, and so on until all cards change the installed base and put all channels with new encryption.
It is worth noting that when there are only two points (or a single HDTV Plus point), the Broadband Dual Lnb works without need Switch 3×4, because both outputs can polarize vertically or horizontally regardless. I've read reports that a Switch 3×4 is required with the new LNB, what might be a result of some installers be putting the key even when the Subscriber is only two points.
With respect to the signal, There is also a considerable improvement when installing the Broadband Dual Lnb, that seems to have a greater sensitivity to the ancient Universal LNB from Sharp and other brands.
