Santa has delivered a wave frontier T90 dish.... I now have someimportant choices to make.....
I already have two dishes. A triax td 78 for all the sky and freesat stuff at Astra 2. This is fed into a triax multiswitch. The other dish is a triax td110 with multi LNB holder. This was used on Astra 1 and hot bird and fed into a emp centauri 17x16 multiswitch. This means I can have up to four sat positions.
I intend to reposition the triax td110 onto hispasat 30 west. With the multi LNB holder I can access sat positions over a 20 degree arc. This means I will then have two fixed dishes at the extreme ends of the arc.. The wave frontier can accommodate up to 16 LNBs over a 40 degree arc which I plant to position somewhere along the arc from 23.5 east to 27.5 west. I have acquired another 17x16 multiswitch. Given that I will have hispasat on the td110, hot bird and Astra 1 on the wave frontier t90, I now have to choose five more sat positions...... I am thinking Astra 3, Sirius 5.0e, Thor 1.0 west then either (A) 9/10 east and 16 east (B) 5 west and 8 west. I am also aware that hispasat and Sirius only use around half the ku band each so I could combine them into one diseqc position. This would give me a chance of adding a further LNB for either 12.5 west or 7 east. I am in the East Midlands. So what would yo go for choice wise and why? I know many of you will say get a motor as it cheaper and easier but I have several sat boxes around the house with dual tuners and several computers with dual sat tuner cards and I was after many channels as possible and total freedom for all tuners to tune in to anything without being affected by other receivers... On a related subject, the 60mm pole mount for the t90 does not look substantial. I am wondering what would be a better wall bracket give the dish and multiple LNB mass and the high wind loading.... I am using alps bullet nose Quattro LNBs so I can have them as close as 3 degrees on the wave frontier t90. |

Blimey...
Will you have any time left to actually watchTV or will it be channel hopping all night? sorry, Just wondered what the main aim of this was. If its just out of interest, then fine by me, but cannot think there is much worth watching on some of those unless you speak the lingo that is.

ah, yes, UPS. Definitely a good idea, but often such things tend to only
last very short times. I wonder if one could make a system which would automatically start a generator and bring that in before the batteries went down for all domestic entertainment systems. I was attempting to move a tape to a computer yesterday when a bad changeover completely ruined it and I had to start again.

My own computers have UPS as well with the sat tuner cards so I'm well prepared for catastrophes/terorism/power cuts etc so I can actually find out whats going on in the wider world..... :-)))) |

What a nice Santa - stopped of in the Czech Republic on his way to you - not sure why you need a X16 multi-switch unless you are feeding a block of flats. BTW a T90 and an EMP switch was the wish list spec' for our flats, however few wanted satellite and the ones that did went for freebies from $ky. I intend to reposition the triax td110 onto hispasat 30 west. With the multi LNB holder I can access sat positions over a 20 degree arc.

Not sure about this - would you not have been better with the Multiswitch MS33/12PIU-6 (33 in / 12 out) ? How are you going to combine the two multi-switches? Given that I will have hispasat on the td110, hot bird and Astra 1 on the wave frontier t90, I now have to choose five more sat positions......

In fact I would have the T90 pointing at 28E, 19E, 13E and ANO, and a steerable for anything else. On a related subject, the 60mm pole mount for the t90 does not look substantial. I am wondering what would be a better wall bracket give the dish and multiple LNB mass and the high wind loading.... You want a 50mm minimum - probably a proper scaffolding pole. You need to compensate for the weight of the dish and LNB's when aligning the pole (which MUST be vertical +/- 0). If you can find a sheltered corner with sufficient view to put yours then this will reduce the problem. I have a 1.2m Fibo steerable erected in a partly sheltered position ~1996. It was partially pulled out of its mounting in gales at this time of year in 1998, but has been sound since. It's view is from ~42E (partly obscured by my conservatory) to ~45W, although these days I only use ~30E to 30W I am using alps bullet nose Quattro LNBs so I can have them as close as 3 degrees on the wave frontier t90. This means you can have 19, 16 & 13E PS I gradually got bored of DX'ing for two reasons - 1. Lots of free stuff on 28E and 2. Most of the decent stuff on other birds became encrypted. |

If the reflector is slightly non-vertical it doesn't matter. Obviously physical fixings are easier if the thing is properly upright, but it can be made to work even if the reflector is on a bit of a tilt. Bill |

So how many LNBs have you got on you t90 and on what sat positions?
What type of LNBs are you using? |

There are five quad LNBs for 28.2e 19.2e 13e 9e and 5w MTI AK54-XT2 MTI AK54-XT2BL Lemon Lemp-40QDL Technomate TM-4 - old Technomate TM-4 - newer The MTI LNBs have never been any trouble I had a Smart Titanium LNB that died. It did not like switching polarity - needed lots of current There was one transponder that the older Technomate LNB would not receive. The new one did not have this problem. I also have a motorised dish with an Inverto Black Ultra LNB I have 4 EMP-Centauri Diseqc 1.1 switches connected to two twin tuner linux receivers. I note you have 5 Quad LNBs and 4 off 4 port diseqc switches.... Am I right that the 28.2E LNB is ponly used for sky & freesat boxes rather than fed into the Twin tuners? As you know, the T90 is capable of a 40 degree spread. As my extreme limits of sat choices are 28.2 East and 30 West, thats a difference of 58.2 degrees which is in excess of 40 degrees supported by the T90. I know there are examples on the net where people have extended the T90's rail. That would probably work if I was not using Quattro LNB's on a multiswitches. For Quattro & multiswitch use, its recommended to increase the dish size up to the next dish size. Thats why I am considering a 80 cm fixed dish for 28.2 E for all the freesat & sky boxes only. A 1m fixed dish at 30 West with a 20 degree Multi LNB holder. As I'm interested in Astra 3 at 23.5E, adding on the 40 degrees to Astra 3 takes me to 16.5 West which is conveniently just past Telstar at 15W which also is a fairly loud bird. The T90's dish gain is not constant across the 40 degree arc, it is more of a parabola, so the extreme sats need to be stronger than the middle sats so hopefully the sat signal strengths will be fairly uniform across the 40 degree arc. This works out quite well as Thor & Sirius, 9/10 E, 7.0E and 16.0E will be fairly near the middle portion of the T90's arc and these are weaker. Coming back to the fixed 1m dish on Hispasat, as mentioned earlier this has a multi LNB holder, I can then access sats across an arc of either (a) Intelsat 901 at 18.0 West to NSS 10 at 37.5W (which includes hispasat) (b) Hispasat 30 West to 45.0 West. I suspect the intervening local terrain, satellte signal strengths and low numbers of Ku band transponders will defeat me somewhat over this extreme west part of the sky will probably limit me to Intelsat 901 at 18.0 West, NSS 7 at 22.0W, Intelsat 905 at 24.5W and Hispasat at 30.0W. |
