    parallel power inserters?

    I was wondering if it is at all possible to parallel the power inserters. Here is my situation. We have had direct tv with no swm8 installed for about 3-4 years. Just three cables from the dish to three receivers (H21)in the house. Since there is no swm8 installed the guide data does not get updated on certain channels. I was wanting to install the swm8,(to be able to get the guide updated) but since we are off-grid, we seldom have more than one tv on or powered up at a time. If I have only one power inserter, and that tv is not used/powered up, the switch would not have power. Therefore, my thought to get this accomplished was to get three power inserters (one at each tv) and put a splitter in the swm line of the power inserters to power the switch. What would happen if two of the power inserters were powered up in parallel?

    Just wondering if this is possible or would work.
    Any advice would be appreciated.

    Thanks

    That doesn't sound like a good idea, but I have to say that there is some other issue in your situation that is causing the guide data not to operate. A SWM8 requires FOUR lines from the dish, and if you have an HD-compatible dish,then each line to your H21 should provide ALL of the guide data and information in your area.

    All of that said, I think it would be a bad idea to have multiple PIs. Instead, you should just have the PI before your splitter and have it connected to an outlet that gets turned on before you watch TV). Also, keep in mind that SWM splitters have ONLY ONE PORT that passes power up the line to the SWM.

      It took some time and emails back and forth to directv tech support to figure out the guide update problem. It is definitely a lack of a swm8 being installed in alaska. Apparently the swm8 was new about the time of my install and therefore did not get installed.

      Back to the parallel pi's. I was thinking having a pi at each receiver location with the swm port of each pi connected to the output of a diode steered power passing splitter similar to Holland Electronics HFS-3D. The input of the splitter would then run out and connect to the swm8 at the dish. What do you think?

      I keep thinking the parallel pi route because receptacles in the house that have tv's, stereo's, ghost loads, etc. are switched off when not in use.

        Did not know you were in AK--that definitely makes a difference in the need for a SWM8.

        I would strongly advise against using any splitter that is not SWM-compatible, because SWM communication happens at a frequency that standard splitters do not support (2mhz).

          okay, I appreciate your help and advice. I have thought of another way to make it work with the inverter. I will install a new receptacle just for the power inserter and then set the "search wattage" on the inverter up so it does not see the load of the pi. This way i can go with the splitters in the ird line as the drawings suggest. This should work. Thanks again for getting me thinking in the right direction.
