Yep - I'm converting a Sky Q wideband LNB - which was installed for Sky Q at 28.2E (and is still used for that) to also add Unicable I/II compatibility so I can feed SAT>IP tuners and a FTA Zapper. I'm using a Durasat DPC-32K multiswitch (the H and V wideband is passed though to the Sky Q box). Annoyingly the Sky Q LNB is 10.41 not 10.40GHz local oscillator so I have to reconfigure the LNB settings in the tuners - but it's working OK now.
Interested in your experiences of the T90 - I've been very tempted by them as I'd like to get a number of satellites between 28.2 E and 5W - though I may not be able to with a single dish due to nearby trees outside my property, and regional restrictions on dish positions...
Do you need any more assistance in config of networks?
A Network in TV Headend is usually used to configure the transponders (DVB-S/S2) or multiplexes (DVB-T/T2 and DVB-C) that you want to be able to receive. Normally you'd have a network per satellite position. You can either use pre-stored satellite lists - which will then autopopulate the muxes (aka transponders) used for that network in the TVHeadned muxes list, or you can manually add muxes (it will prompt you to select which network the mux is for)
You then associate the network with tuner or tuners (and in some cases Diseqc or Unicable I/II position locations for that tuner)
Example 1:
2 x LNBs with single outputs - one pointed at 19.2E, the other at 28.2E - each directly connected to a tuner input.
Tuner 1 would be associated with an 'Astra 19.2E' network, and all the transponders for Astra 19.2 would be associated with that network.
Tuner 2 would be associated with an 'Astra 28.2E' network, and all the transponders for Astra 28.2 would be associated with that network.
Example 2:
4 tuners, all connected to separate outputs of a Quad LNB pointed at Astra 28.2.
Tuners 1 to 4 would all be associated with an Astra 28.2E network, with the transponders for Astra 28.2 associated with that network.
Example 3:
2 x single output LNBs (one at 28.2, one at 19.2) connected via an A/B Diseqc switch to a single tuner.
Tuner 1 would then be configured with 2 networks - 'Astra 28.2' for position A, 'Astra 19.2' for position B etc.
Example 4:
2 x Wideband LNBs pointed at 28.2 and 19.2 via a Unicable II multiswitch, connected to a 4 input tuner.
The 4 tuners will each be allocated an SCR user band and PIN at a given frequency. The 4 tuners can all be allocated an Astra 28.2 network for position A, and a 19.2 network for position B. The tuners will then tell the multiswitch which LNB/position to switch to each user band when they request to tune a given user band to a given transponder.
e.g.
Tuner 1 will send the signal via Unicable II to the multiswitch 'Please tune SCR Channel 1 - which is allocated to me and is at 1210MHz with PIN 37 - to Satellite Position A (selecting 28.2E LNB is to be tuned) and the transponder at 10.847GHz with Vertical polarisation' - that will then send that Astra 28.2E transponder shifted to 1210MHz down the cable
Tuner 2 might then send a signal via Unicable II to the multiswich 'Please tune SCR Channel 2 - which is allocated to me and is at 1420MHz with PIN 18 - to Satellite Position B (sleeting 19.2E LNB is to be tuned) and the transponder at 11.361GHz with Horizontal polarisation' - that will then send that Astra 19.2E transponder shifted to 1420MHz down the same cable.
(NB TV Headend seems to use an N-1 numbering scheme - so SCR Channel 1 is ID 0, SCR Channel 2 is ID 1 etc.)
