    What is(are) the specific difference(s) between the SL3K4NR1-01 and the SL3K4NR0-02 Slimline 3 (non-SWM) LNBs? I was shipped the former to replace the latter in an existing setup, and I do see an additional "knub" on the former that I'm concerned may be an issue in fully inserting the LNB into the arm (it's EXTREMELY cold up here in Maine, and I don't want to pull apart a well-weatherized connection only to not be able to complete the replacement). Thanks in advance for any experienced guidance here.

    maybe different manufacturer but the LNBs are the same. all Slimline LNBs have the "knob" at the bottom

    They appear to be very little difference in Google images searches I found.

    Those LNBs are interchangeable.

    DirecTV model numbers follow a pattern: Part Revision - Manufacturer

    Here the part is SL3K4N.
    The revision is designated by R#. This is not necessarily consistent between manufacturers.
    -01 is manufactured by WNC and -02 is manufactured by Probrand/Eagle Aspen. There can be differences between manufacturers. The differences are usually cosmetic. As long as the part is the same they are designed to be interchangeable.

    Thanks to all, but "extra credit" goes to dielray, for tying the model numbers to the manufacturers. The troublesome unit is much more temperature sensitive (i.e. stops working at 10 degrees F) than anything I've worked with in the past in this application (typically zero and below), and it appears from the posting that my replacement unit is a Winegard, for an existing Eagle Aspen. I do realize that temperature failures can be related to something other than the LNB, but it's comforting to know when I'm working sub-zero that my replacement is from a different manufacturer, so I can test my theory as well as the respective units. That information was exactly of the nature I was looking for, and I'm grateful that someone (and indeed everyone) took the time to pass it along.

    FWIW, if I had a choice, I will always choose Eagle_aspen among the other LNB manufacturers

    Proves what?? the wnc issue? All dealers in the area were sent wnc lnbs that were incompatible with h24-700 receivers. HSP had no issues what so ever because they were using h24-100 refurbs.
    All the dealers were to blaime for lously installations, it took 9 months for directv to admit there was a problem and sent out a tech bulletin.

    As soon as it went below zero my friend at HSP was swapping eagles left and right at service calls this year. He called and told me about it and thats all i had in inventory was about 90 eagle aspens and i started freaking out , thought we were gonna do this all over again.......aparently the ones i was using were different models, i have had any issues with mine.

    How can a LNB be incompatible with a certain model of receiver? Unless it was a legacy LNB and a SWM only receiver or vice versa I don't see how that's possible??

    IIRC 4 years ago D12-100s had a software issue that made them not play nice with Zinwell LNBs, so there is at least precedent.

    I'm not sure what Jordean is referring to about historical problems with the H24-700s. I don't remember seeing a blast facts on it. Though right now we are swapping out H24-700s non-stop on SWM systems for intermittent 771/775 and our SWM LNBS have mostly always been WNC. This has only been happening for us since 0x0740 was released in the area however.

    Interesting. The reason I specifically asked Jodean about that was because I have 7 H24-700s, so if there was a problem that might affect them I'd want to know. I don't use a SWM LNB, but mine seem to be working just fine off SWM16s...

    Perhaps because the highlighted part was true

    would love to know why a receiver would work with a EA SWM LNB and not a WNC? how can a receiver tell the difference?
