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 w= ith the much taunted Yaosheng adapter, which however isn't 12V (it needs 42= V) and which gave us a lot more outages than the Starlink router with Ether= net 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 spe= eding 4WD and seems to be quite different from a residential class Dishy. P= resumably that will run off 12V. Cost is significantly more than

At least two articles I've read tonight confirm they are still AC powere= d

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

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

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 av= oid the geostationary arc, which also means that the sats it talks to are q= uite 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 sat= s are, hrmm, actually 22k's might even be the stratosphere, I'm sure someon= e will correct me :)

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 u= se cases are jitsi, VoIP, Weather, twatter, and odd youtube, I dont have ne= tflix or such, and for FTA TV, there's VAST and foxtel uses the same satell= ite as VAST so ...yeah, there's that ;)

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 rat= e data stream that really eats the watts.

That doesn't sound well designed if thats the case, I mean we're only ta= lking 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 p= ut 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 :)
