Wow what a day! Finally had time to really put this thing to the test and all I can say is WOW.
Here are some pics of us Meshing and temp data from the other day. I just put the temp logger inside the unit to see how hot it gets inside the case over a 48 hour period of hot weather here in the Northwest and of course I’ll get that out to y’all! Coming up with a more simple DASS-RS / MOAN AND coming with out with a itemized price list with links! Oh and of course instructions on how to make one
And as always: THANK YOU SO MUCH FOR YOUR SUPPORT! Y’all have been awesome and I look forward to getting this and more out! MESH ON!!!
Thanks. I’m learning as I go along so bear with me pls.
As someone mentioned above, the max EIRP allowable by the FCC is 36 dBm, do you know what’s the EIRP of the goTenna mesh out of the box? Your antenna is actually 5.15 dBi, if I’m not mistaken, so would it take that much higher gain to provide a worthwhile improvement?
I have found antennas like that but I was looking for something smaller, something like this but from a less sketchy source.
Don’t all these solar panels that they sell for charging phones come already with everything integrated? I think you can just plug it in, most if not all of them are solar panels/power banks, aren’t they?
I think the ERP of Gotenna Mesh is 1 watt. However I wired in straight up to the amplifier bypassing a capacitor. More output that way.
dBi (IMO) is great but I go with dBd (The idea of an isotropic antenna is great however: “An isotropic radiator is a theoretical point source of electromagnetic or sound waves”. I deal with dBd due to it having a real life reference point). The antenna I got eBay, I don’t find it sketchy. I ran it through my antenna analyzer and the SWR was great across what it was designed for (902-928 Mhz). It also has 3 dBd of gain, thus doubling the power output of what is coming out of the unit. It was also designed for that frequency range and the antenna you have listed is not. The cons of that is having a poor SWR at the GoTenna Mesh frequency range (902-928 Mhz) could damage the unit and/or degrade performance. Only use an external antenna that is propose built for the 902-928 Mhz frequency range! Or else risk making your Mesh unit into a paperweight!!!
So lets say the ERP of my unit is 1.25 + 3 dBd of gain = 2.5 watts ERP and that = 34 dBm and that is below the FCC max of dBm. And really I am just some guy playing with radios, so do the FCC Part 15 rules and regulations apply to me? Maybe, maybe not. Ignorance is bliss.
Now when I put this on the next MOAN I’ll have 7.6913 watts of output. IMO, get kick ass coms up first, ask questions later (or never). Not trying to get an attitude or anything I just like to max out the performance of cool coms gear. I doubt the FCC would care if I put a MOAN up with the listed yagi somewhere on the PCT (Pacific Crest Trail) for long haul coms back to a more populated area or made some for my friends who do SAR whom run into reliable coms issues all the time. Like I said before: Get kick ass coms up first, ask questions later (or never) and hide your units well
@andy_o I do like the idea of a smaller MOAN type node and am coming with something in the near future that’s small, solar and with a smaller omnidirectional antenna (hopefully one with a ton of gain!).
At the end of the day I am just trying to make GoTenna Mesh a real tool for people if the grid goes down for whatever reason. I’ve been deployed to real disasters and if you can’t communicate with your loved ones, well that’s a very scary thing something I saw first hand while deployed with the Red Cross in Joplin Missouri back in 2011. It was the deadliest tornado to strike the US since 1947. I was boots on the ground less than 30 hours of it happening and what I saw totally made me appreciate communications to a degree I find hard to put into words.
Why GoTenna Mesh to me is so amazing is that allows reliable communications from the ground up NOT relying on any of the top down infrastructure (cell phones, landlines, internet ETC). Hell even amateur radio to most people is hard to learn and understand! However with GoTenna Mesh all you need is a smart phone and a Gotenna Mesh unit and you have a device that has a TON of potential. Not just that, GoTenna Mesh/the GoTenna app are super easy to use, everyone has a smartphone and of course know how to use it! Being an extra class / VE ham is cool and all BUT GoTenna Mesh is a real tool anyone can use, IMO it’s a total game changer.
What my vision is that enough people come out with MOAN type units across the county so if and when something happens (god forbid) people can communicate with their loved ones, get help, and have piece of mind. A vision without action is only a dream, I am not a dreamer. I am an action guy. So lets do this!
“People powered communications baby, we are the network!”
