Oneweb is not using the same technology. They're both using phased array, but SpaceX couldn't solve the low price point like oneweb, so they have it mounted on a motor. That will surely increase cost and reduce longevity.

Oneweb is another story, and regardless of their antenna, it's not clear how they're going to monetize.

They're both using phased array. The motorized mount is only for pointing optimization during the installation process; it's not going to be constantly motoring around. (and personally, I wouldn't be surprised if SpaceX drops that eventually... they're trying to minimize installation costs to lower than current satellite dishes so the customer or unskilled worker can basically just plop it in the ground without adjustment while still optimizing the signal.)

Whether or not SpaceX "couldn't solve" the low price point is unknown. I'd be skeptical of anyone who claims they can't do it. Don't be too willing to buy OneWeb's PR. "Special sauce" is marketing speak. Execution is what matters. (This works both ways... OneWeb will eventually be using reusable rockets--i.e. from Blue Origin and others--like SpaceX.)

Please cite a source on that one. If they're putting a motor on just for installation to point to roughly the right spot, that's a ton of money spent on a motor for a single-use item. That will again point to it not being a consumer product. What's more likely is the motor is making up for the poor scan loss of the cheaper phased array.

But a one-time-use, non-precision motor is pretty inexpensive. A precision motor that has to run 24/7 outside in the elements is super expensive.

Musk is trying to get rid of the $100 cost of professional installation by substituting with a $10 motor. I'm not sure it'll be successful (I wouldn't be surprised if professional installation still ends up happening and they eventually delete the motors), but that is the plan. It's just to get a good view of the sky, not to scan. A reliable scanning motor would cost a lot more. (And they need to track multiple satellites at once... can't do that with a single array steered by a motor, has to be beam-steered.)

Instructions are simply: - Plug in socket - Point at sky These instructions work in either order. No training required." https://mobile.twitter.com/elonmusk/status/12145487640542167...

Trust me -- it's NOT inexpensive. Maybe your definition of inexpensive is different from mine, but adding $20-$30 onto the cost of every install is a massive expense, especially when you still have to send a trained installer out to do it. You can't rely on an end user to do it since there are all kinds of issues with placement/blockage/etc. If you choose to ignore that, you spend more money on customer support to help them install it. Notice Elon doesn't say that end users will do it. He just said no training required, just like you don't need training to install tiles in your house either.
