Starlink

Pay climber to install a Starlink @ top of healthy fir ?

JK (mostly).... but I hang-out here to see what inventive things people are doing, not just on Tractors.....

Rgds, D.

I know several folks who have done just that. Starlink says that they can handle up to 3' of tree sway.

I know a guy who did that: paid a climber to install antenna over 100' up a redwood tree. That was for WISP (Etheric, Surfnet, or Ridge Wireless).

Good to know the antenna for Starlink can tolerate some movement.

I got my fiber now (Frontier). 500M for $47/mo. Replaced my old DSL (28/2M for $90/mo). Funny thing: does not seem any faster, except for uploading a video to Utube.

For most things, 20Mb download is fine. Biggest speed limiter is the server you are accessing.

3 feet is impressive.... when I was joking about that, I figured you'd need a mobile version of Starlink, but apparently not.

If a giant tree is moving more than 3 feet in the wind, downloads are probably your least immediate worry !

3' of motion even 100' up isn't a lot, that's like a 5-10mph breeze...

If they can only handle 3' of motion (in how much time? I assume that's 3' over a few seconds) it's not going to be a good time during a decent storm.

I had a T1 line for about ten years, and then the company that was paying for it who I'd worked for during the first seven of those years finally cancelled the service... after that, we had a wi-fi-like connection to a local provider for a while with an antenna about 70' in a ponderosa pine. Not being at the top of the tree, there was a lot less sway at that level.

Depending on the service level, you can use it in motion. Plenty use it on boats & some use it while driving. A tree would be more stable than those.

3' of motion is nothing to the cone of radiation coming down. Uploading will most likely take a hit though. My head hurts when I try mathematics but 3' of motion on earth is probably many miles at the height of the satellites (~342 miles away).

Edit: Forgot to mention-The satellites are moving too. One revolution around earth ever 90 minutes. That's crazy fast. Far faster than a tree sway.

Orbital Fizx calculations..... we're not just a bunch of pretty faces around here !

The beams down and up aren't that tight, but the angular shift would absolutely need to be accounted for. Phased array antennas are accurate, but there are limits. I would remember that the base frequency is 5GHz, so there is ample sampling to update the array target angle compared to wind motion in a tree or an airplane (500+mph...). Since it works in aircraft, anything terrestrial is a piece of cake.

All the best,

Each Starlink satellite is only in view for 15 minutes or less. So the dish has to track it across the sky at a pretty good clip & then sync up with the next one before the first is out of view. Gen 2 dishes were motorized, but only to point towards clear sky. The antenna in all the dishes are phased array antennas that can be steered instantly electronically by a fair bit. Probably at least 30 degrees. Compare that with orbital velocities & driving or even flying speeds become easy to adjust for.

I assume they dropped the motors on the Gen 3 dishes for cost. And the fact that they now have enough satellites it's even easier to have one in view as long as your pointing vaguely towards clear sky.

On a recent camping trip my gen 2 dish kept pointing itself into the trees instead of open sky. Still had 99.9% connection though so I just left it there.
