If I buy and install the slimline-3 dish now, will it work with the DSR704s?
I have a pair of DRS704 DVRs (1980s vintage) that I have upgraded over the years so they now have 1 TB SSDs for recording. I own the DSR704s. They are currently connected to a 3 LNB oval dish (4 wires... two going to each of the 2 receivers built into each DVR. I have been told that sometime in 2019 this dish will stop working, and I'll have to go to a slimline-3 dish.
My question is..... If I buy and install the slimline-3 dish now, will it work with the DSR704s? I understand I'll have to use a signal splitter to feed the two DVRs. It's just that when I look at lists of receivers that are compatible with the slimline-3 dish, the DSR704 is not listed.... and I'm thinking that might just be because it is so old DirecTV might have forgotten it even exists. I plan on eventually upgrading to a Genie and Genie Mini to replace them..... but I cannot get an installation for several weeks (it's a nightmare where I live.... I waited three weeks for an installation today, and the guy finally showed up 6 hours late at dusk... too late for the installation.... and told me the soonest he could come back would be another two to three weeks, and during that time frame my wife is having major surgery, and his coming them just won't work) In other words, circumstances are such that if I don't get the installation in the next week, I won't be able-to for a couple of months. I'm thinking I can just upgrade the antenna now, and have them send me the Genie and Mini myself to hook up later (they already told me they'd do that). So the issue at the moment is if the Slimline-3 dish will work with the DSR704s.
My alternative is to call Dish. They said they can have their installation done tomorrow.
