@@вечная_мерзлота check my other videos for the full build. I used station g2s for it instead

@@vinceparker2888 So here is the issue with that. The Station G2 uses an esp32 module and on that module is where the Bluetooth antenna is. There is unfortunately no way to make the Bluetooth external because of this.

So there is actually a way but you have to mess with the esp32 module to do it. I’ll post a photo of this in my posts here on youtube so you can see. @vinceparker2888

I split it at POE becuase I do not intend for this to be the last permanent version of this super node. I will be powering other devices that will take the usbc power handoffs and the station g2s will have a direct power feed via the side connectors instead of the usbc port. This will allow me to remote manage the station g2 units via their usbc ports from the mini computers (whether they be raspberry pi or otherwise, I haven’t chosen yet) I also wanted to isolate the two power feeds as much as possible and using a usbc Y adaptor doesn’t really do that as there’s no active electronics there to prevent crosstalk. In the POE adaptors there is some level of isolation granted on the Poe side.

@@TechAirSpace This tower site gets us great range. For 915mhz ISM band Meshtastic, we’re seeing Los Angeles and Santa Barbara from Mexico. On 5ghz we have links up to 72km using the parabolic dishes.

Wow 955 of them? That is alot of work.

@@ke6vdwit sure was…I installed 12V LED pixels along the roof line on the front of my house. Lights are spaced every 2 inches. They stick out just enough under the facia that you can’t really tell they are there, until you turn them on. No more stringing Christmas lights and I can change colors or patterns for more than just one holiday. I am digging your project though. I may do something similar here. If you ever make another node box save yourself the headache and use that step bit. I would have had the bulkhead holes done in less than 1 minute and it’s way safer!

@ You are right! You inspired me to order some step bits. I wish I had them for this project but had to wing it. I suppose it’s better that I drilled it in stages otherwise I can imagine the whole box spinning wildly as the drill catches plastic spurs. Are your led strips weatherproof?

Snarky there. It must feel good to be a legend in your own mind. First of all, the g2 sideplates are not connected together. The double sided tape mounting method was temporary for the test as I said in the video and the spacing prevents any metal to metal contact. Once the final version is decided, everything will be mounted with nylon risers and nylon screws through the plate. I needed to determine if I was going with two airframe filters or two of the other filters. I chose airframe. Now I can layout the setup and permanently mount things. There is nothing compromised in this build whatsoever. Losses from connectors? The station G2 provides an AMPLE 4W to easily compensate for connector loss and still meet legal requirements for Effective Isotropic Radiated Power. The cables are LMR400 variant and were selected as short lengths to mitigate as much insertion loss as possible. Past that, the connectors, well, they are connectors. I'm not about to open the filters and solder things to avoid the connectors, it would be a mute point. The POE converters do not emit RF harmonically or directly in the frequency ranges of the ISM band. They were selected for this reason. It always surprises me when comments come in from those who think they know it all and didn't even watch the whole video. Congratulations to you as well, Sad Ham. So, please, 3d print yourself into a box.

@@ke6vdw You *JUST* posted a video replacing the nylon standoffs and screws with metal screws, then proceeding with your "test", so I have no idea what you are saying when you claim the plates are "not connected". Bottom line is you cannot determine if it "works well" when you've fundamentally changed the RF behavior. If it *DOES* work well, you state you'll be changing it entirely again by going back to isolated side plates and different mounting ? Then what's the point at all ? This test offers no real value other than the qualitative comparison between the filters… literally nothing else (and zero baseline comparison to see if no filter is better). The low power levels at work here for the receive side are what really matters, which was my point about the connectors, cables, and filters. Nothing comes for free. Extra transmission power means literally nothing if you don't see the node transmissions in the first place because you've "lowered the noise" by inadvertently also lowering the signal. This is especially true with Meshtastic networks since the very nature of chirp spread spectrum signaling makes it more power sensitive than noise sensitive compared to standard signaling methods (where RF notch filters are more beneficial). The only way to know is to test, rather than just assume a filter will improve the final SNR. While doing similar tests for my Helium node deployments, I found the cabling and connector loss amounted to essentially throwing the baby out with the bath water, and so I re-engineered my node enclosure to remove as many connectors and cable length as possible, even at the expense of having to build a custom-sized weatherproof enclosure. The results were quantifiable only because of rigor in testing rather than just tossing "best practices" at it and hoping for the best. Your knee-jerk reaction to ridicule rather than affirm the concerns makes me question if your desire is to do something cool and useful here or just be praised for doing "something". "Legend in your own mind" ? Hrmmm 🤔

@@fiveangle First of all, ridicule is rude. Don't expect a kind reply to a rude opening. Ridicule is the act of using unkind words or actions to make someone or something look foolish. Synonyms of ridicule include deride, mock, and taunt. Ridicule implies a deliberate often malicious belittling. Why do I have to teach you how to be a kind human? Second, the screws are not touching the metal plate, period. Not sure why you do not get that.

I’m a rebel! Lol Really though that’s just an extra table not dining room. Plastic and nothing really scratchy to harm it. That table is soooo thick and hard and HEAVY. It took 4 people to put that table in there.

Plenty of folks have already done so. The filters have always provided a very noticeable and positive difference. Even the "cheap" filters are better than no filter.

Actually I did but I forgot to mention it. Without filter going straight to Yag, we only saw around 200 nodes detected. This was close to what we got using the lcom filter.

@@DirtyPlumbus do you mean the g2 units or the airframe filter?

@ke6vdw G2 unit.

@@DirtyPlumbus Station G2 is the best. I love them the most.

@ke6vdw I looked them up. A bit more expensive than most, but the specs look like they're worth it. 4 dbm increase in signal is nothing to scoff at. Definitely a bit more trouble to power though.

@@BrooksWB6EDK John is a close friend and we all love him.

Thank you. I’m glad you enjoyed it.

It’s in the attic. I don’t care how it looks. 😂. In this case it got the end results I needed. Not trying to engage in a plumbing project although yes I could have added a 45 with a clean out plug on the end and drilled into that but not personally desired by me in this case. It’s an open ended air pipe.

Yes they see eachother direct.

That’s great! I’m very happy to hear reports like this. My nodes are doing very well covering most of San Diego and surrounding regions. I’m getting great distance out of my Alien antennas too so it’s just been a great experience.

I know, right? So much stuff up there! It's a real jungle! I think we have about 80 dishes on there

@@KateHikes1933 A Yagi antenna, also known as a Yagi-Uda antenna, works by using wave amplification to direct radio waves in a specific direction. This allows the antenna to receive and transmit signals over longer distances and with greater clarity than an omnidirectional antenna. Here's how a Yagi antenna works: Elements A Yagi antenna is made up of a long boom, a dipole, directors, and a reflector: Boom: The long pole that points in the desired direction Dipole: The active feed line that absorbs and radiates the signal Directors: Branch off from the boom at right angles, helping to direct the signal and provide power and gain Reflector: Sits behind the dipole, reflecting the signal in the opposite direction Wave amplification The directors and reflector work together to amplify the signal in one direction and reduce it in other directions. This is achieved by using phase cancellation, where the radio waves are carefully sized and spaced to reinforce each other in a specific direction. Directionality The Yagi antenna's directionality comes from the reflector blocking waves coming from the rear of the antenna. Yagi antennas are often used for rooftop television antennas, amateur radio, CB radio, and cell phone reception. They are directional, so they must be pointed directly at a signal source for optimal performance.

Thank you! I’ve been working hard on it.

Dual Router Meshtastic Node

This is a Meshtastic LoRa Dual Router Node running on the 915Mhz Band.

What’s that mean?

It’s got 290 views. Not a lot but hey it’s handy info for those who want to learn

I see you study the vernacular of NotARubicon 😂

Same here. Solar node with 15 dB antenna up 40 feet. What are you putting up?

Working very well! My upcoming video will fill you in. (Still editing it but I’m slow)

How dare you say that! My car is made entirely out of paper mache. Really though, same test with antennas mounted outside on my TWO external vehicle mounts yielded the same exact results. 😊😂

@ke6vdw lol. I believe ya. I have an alfa 915 but it didn't fair any better than the included pcb antenna on the RAK wizblock. But I think I got something else going on

Found it! 👍

Good. I had made another short video about it too just in case.
