Relay node/MOAN on Yerba Buena island?

Anyone interested in collaborating on a relay node on Yerba Buena island (San Francisco)? The measure tool on GMaps tells me it’s ~3km from the Embarcadero shore, and its elevated position could provide a good relay point.

Side-note: I don’t know about the legality of putting a MOAN there, which could put an end to this.

@zestuart Better to ask for forgiveness than permission.

IMO: Get coms up first, ask questions (or get asked questions) later. Oh and hide it well! :slight_smile:

Adding @JasonJava @dbfish who I believe are in the SF Bay Area as well!

Should also do Alcatraz and Angel Island!

Oh an island-to-island mesh would be a good time.

Into this! The islands can also interconnect the East Bay to the South Bay to San Francisco to Marin. :slight_smile:

Oh heck yeah! I LOVE this idea working on a smaller MOAN unit and will get it out ASAP!

Aye: a mesh across the Bay is where I wanted to go with this, but was a bit
stumped by the range from Yerba Buena to Oakland.

I’ll look up the range using a aero chart and get back to you with more details, that sound like a plan? Than I can give you some good ideas. Need to sleep now BUT tomorrow for sures…

I’m keen to learn how you calculate this

2 miles to SF, 3.5 to west Oakland. Rooftops line of sight should be easy (if you can find and get permission for the right roofs). If you go higher up the Berkeley hills could probably hit it. UCB stadium / tower about 7.5 miles.

I know of a good tree above Rockridge that would do very well. ~500m AMSL
too.

Holler at me! PM/DM with your location(s) and where is the island is and I’ll show how how to do the RLOS (radio line of sight) calculations. :sunny:

Can you do that publicly so we can all learn? :slight_smile:

It’s been a while but I think this is what I last used:

Island high point is about here

I made a Google Map with what I think optimum locations are, if we could put MOANs on them:

3 seems quite doable. You’d just want more of 'em in dense areas but not sure if you’re going for full-on coverage everywhere or just the cool-factor of being able to communicate across the Bay :slight_smile:

Paging @dbfish @gua742 for better feedback

Keep in mind the 4 point maximum hop distance for mesh with current firmware. That means you want to optimize star patterns around high points (maximum point to point over length toward populated areas). I think someone will probably develop a fix for long links like this using the API and store and forward hardware :wink:

You maybe? I think this would be great.
