T-90 Wiring Layout

[SVHD]

I just ordered two Toroidal T-90 dishes and they should be here sometime next week. I'm in the process of trying to lay out my wiring diagram. I will have a total of 9 LNBF's-- 5 on one dish and 4 on the other. Can anybody tell me how to hook up this layout to four receivers, using multi switches, discq switches, 22kiHZ switches, etc. Please explain in detail. Thank You.

If you only have 9 LNB's why the heck do you need 2 dishes?

I have 13 LNB's on mine (72,74,79,83,85,89,93,97,101,103,107,110,119)

what satellites are you going to aim at??

The reason that I got two T-90's is because of the 40 degree arc and the fact that I have to go from 74west to 129west. I want to get some of the free to air sats but I also have a dish and I have to take into consideration 110,119 and 129. Therefore, I will have 4 LNBF's on one dish and four on the other to overcome the 40 degree arc limitation of the T-90 and I need to hook up three and possibly four receivers. Please help me with some kind of wiring diagram to accomplish this. In advance, thank you for your time, patience, and help.

When you want to have multiple receivers to be able to use the same LNB's, the thing to use is a multi-switch.

But before you can use a multi-switch, note there is a problem with the "polarity" (H/V) when using a SINGLE coax connection LNB.

You need to use a DUAL coax connection LNB. This is because the receiver applies 13 volts to the coax cable to get one polarity and 18 volts on the coax to get the other polarity.

You CAN'T have one receiver applying 13 volts to a single coax connection and the other receiver applying 18 volts at the same time!

The trick is to use a DUAL coax connection LNB. Then the multi-switch has two connections to the LNB. One connection is always 13 volts and one polarity, the other connection is always 18 volts and the other polarity (for use by the multi-switch). Then the multi-switch determines what polarity each receiver is wanting and connects the receiver to the appropriate connection on the LNB.
