I'm still trying to understand why my 5 x 8 muultiswitch did not work during my install last weekend and my options going forward.
I had a JVI Trunkline Model 35-TRDS8, 40 - 2150MHz, 5 x 8 multiswitch and a dual LNB dish going to 4 receivers, 2 of them directivos. Everything worked great from the time of my original install almost 5 years ago.
On Sunday we upgraded to HD which meant replacing my dish with a 3 LNB, and replacing the 2 DirecTivos with 2 HD DirecTivos (actually I got rid of the old receivers and replaced those with the DirecTivos). The installer used all my current cabling. We added an antenna, as I have great line of site to the Sutro tower in San Francisco.
Initially we could not get through Guided Setup. On the signal strength screen, it showed all 3 satellites and great signal strength for each transponder on each satellite. However, in the next step it would fail and say there was a problem with 2 of the satellites.
The only fix was to replace my 5 x 8 with a 4 x 8. Everything worked as soon as we made the switch, and we used a diplexor at each end to get my locals to one room.
However, I originally bought the 5 x 8 so I could send the antenna signal to all rooms. To do so now, without running additional cable, I guess I would have to add a splitter for the antenna, and then 4 antenna leads to 4 diplexors at the multiswitch.
So to avoid that I have the following questions. Please don't get too technical with the answers, put someone, please do help me get this figured out. Please try to answer my questions as directly as possible.
1. If the 5 x 8 had worked would I have needed any diplexors at the switch? Is the purpose of the antenna input to essentially act as a diplexor for each of the 8 outputs, so you only need a diplexor at the receiver end?
If so, that is clearly the cleaner solution.
2. Is there a way to get my old multiswitch to work?
The installer said that the 4 wires from the dish to the multiswitch were all equal; it didn't matter in which sequence they connected to the multiswitch.
3. Is that true?
4. Is the solution in the wiring at the multiswitch or at the dish or neither?
5. Is the problem that my multiswitch is just not compatible with the switch built into the dish and I need a different 5 x 8 multiswitch?
Thank you in advance to anyone taking the time to answer my questions.
