3 Questions about the Wally:
1) If the Wally is a second receiver, it is only a $7 monthly fee, or is this more expensive?
2) Right now I currently have two 211k's and the entire house is RG59 cable through the walls. I know the hopper system doesn't work with RG59, but would the Wally? Could it just replace the 211k's with the Wally or would I need to pull RG6 cable?
3) How large is the Wally compared to the 211k?
After spending another day interacting with the Wally in our RV, I can now confirm it works just fine with the Winegard Pathway X1 ODU we have roof mounted on it's primary port. I have not tried it as a slave yet on the second port. I can not get my 211K to work on the secondary port either, but that could be some cabling issue that I need to resolve. I'll be mucking with that more today.
I also can not get the EHD from the 211K working with the Wally. It doesn't see it plugged in, message on the screen when I go to the DVR function says "To enable this feature, please plug in an External Hard Drive". I'm not giving up that easy, it could just be it does not like this particular EHD. I'll try another but it probably won't be until our next trip out in April at this point, and I always have our 211K to fall back on. I also noted when logged into my account, it clearly says this receiver is not enabled for EHD, so I may also have to check in with them later today before I go after another EHD.
To answer your questions zippyfrog:
1) It's no different from any other add-on receiver type, I can't see the exact fee on my statement because I haven't had it a full month and it's not showing on there. I assume this is the correct price because that is what I was told my bill would increase by as a new monthly total amount, compared to the old.
2) I can not advocate for using RG-59 on any installed satellite system. It is improperly gauged, mostly likely not properly frequency swept, and can lead to injector burn out within the receivers. The 211K is built for the rigors of probable portable service, so it is over-built. If I were in your shoes, I'd probably be more comfortable 'cheating' it with 211K's than anything else. The 211K is also in a metal chassis for that reason. The Wally is in a 100%, light weight, fancy-smanshy plastic chassis. My hunches tell me it is not quite as rugged, and probably not as stoutly built internally. It has no coax output, so if you do any sort of coax back-feed sorcery, that's a no-go.
3) My best guess, if I were to set the Wally on top of the 211k, total surface space taken is maybe about 60% of the size of the 211k. If I have time later, I'll take some physical measurements of each and post them if they are not available online somewhere (I haven't looked yet - maybe in manuals?).
