    I bought a house that has a 3lnb dish with multiple lines coming in. In converting to SWM, can I use one of those lines or do new lines need to be strung?

    If you convert to SWM by replacing the LNB at the dish, you only need one line and you can use one of the lines you have.

    He can only replace the LNB if it is a Slimline 3 LNB. Isn't there a 101/110/119 round dish 3 LNB?

    Either way whether you need to replace just the LNB or the entire dish, you can use any of those cables. If there are four of them you may want to leave the other three be rather than removing them, just in case someday you expand your system beyond the capability of a SWM LNB.

    Though since the official installation guideline ("SPIG") which many installers follow calls for four lines connected to a P. III triple sat. oval to a four barrel ground block even if not all are used. The four lines can therefore nevertheless be a tell-tale sign of a possible P. III dish the TS has.
