The "RV" option available in Australia and NZ at this time is indeed the residential option without the cell lock. It's intended for stationary use and assumes that you have a mains (AC) power source. We've tried it here with the much taunted Yaosheng adapter, which however isn't 12V (it needs 42V) and which gave us a lot more outages than the Starlink router with Ethernet adapter.

There is also a "mobility" option available here (or at least they offer sales consultations for it) that's shown mounted flat on the roof of a speeding 4WD and seems to be quite different from a residential class Dishy. Presumably that will run off 12V. Cost is significantly more than

At least two articles I've read tonight confirm they are still AC powered

The RV option is AC powered, yes.

The significant cost is for the mobility "pro" version, one article indicated 599 for the standard (I assume that's USD but can't confirm)

I think, as on this mailing list, that a lot of people confuse the RV (mobile in the sense that you can take it to other places) and the truly mobile version (usable *while* you move), so the "standard" is probably the standard residential unit on an RV subscription.

So looks like we *still* have to void warranties and hack it for 12v.

We use it with a portable power station.

meaning that most satellites Dishy talks to are more like 800 - 1000 km away. Near the Equator, Dishy will remain in "coffee table" position but avoid the geostationary arc, which also means that the sats it talks to are quite a bit off to the side all of the time.

Still a lot closer than 22km's up in the troposphere where Aus's NBN sats are, hrmm, actually 22k's might even be the stratosphere, I'm sure someone will correct me :)

Yes, that needs correction. Aus's NBN sats are geostationary, that's 35,756 km above the Equator, anything at 22 km would need to be a HAPS (under development in various places but not operational at this time) or face early demise because it's still very much in the atmosphere - some military jets fly as high as that, as did Concorde I think. Space starts at about 100 km.

We've observed that our Dishy consumes more power during large downloads than during uploads, which suggests that transmit power isn't

Something to be mindful of then if that's the cases with all units, my use cases are jitsi, VoIP, Weather, twatter, and odd youtube, I dont have netflix or such, and for FTA TV, there's VAST and foxtel uses the same satellite as VAST so ...yeah, there's that ;)

Which might just blow your cigarette lighter fuse - in some vehicles, these allow for as little as 8 amps (and most plugs get hot at that current, so there's an immediate voltage drop there).

the main factor here. It appears that it's the signal processing that is needed to receive and demodulate the incoming signal with the high bit rate data stream that really eats the watts.

That doesn't sound well designed if thats the case, I mean we're only talking a few hundred mbps on a consumer unit if you're lucky.

Incidentally, with more birds in the sky, Dishy seems to be willing to put up with a bit more obstruction nowadays:


If you have this level of obstruction at a permanent location, why not put it up high in clear(er) view of the sky :)

1) Because my wife put it there while I was at APNIC56 ;-) She had visitors and needed the use of the outdoor table on which it lived until then (which had a much clearer view of the sky but has since moved from that hibernation location to a summer position where it hasn't).

2) Can do, but by the looks of it I don't need to.
