When you snipped off the soldered end connection of the red wire....did you change the antenna length? Or is the length measured from the connection point onward? or does 1/4" inch not make a big difference?

What did he replace it with? The video is blurry. Was it just a piece of electrical wire?

Are you Mr Spoon , name Paul?

What mode are you operating from (client, router, etc.) I ask because my nodes don't show up on the Internet map.

Am I to understand that you are using Bluetooth and Wifi at the same time? I didn't think that was possible. What mode are you using? Client, router, etc.

Unfortunately you left out the most important piece of the Dipole antenna. The common mode choke, even with only 100 mw this is important for two reasons 1 you will end up with standing wave nodes on the coax shield. 2 These nodes will distort the expected donut shaped radiation pattern of the dipole antenna and reduce the quoted gain. The old guy that told you to make sure that you have the centre conductor element on top and the braid conductor element on the bottom is correct in advising you to do this, but only because you have no common mode or in this case shield choke at the feed point. This antenna you have made will perform just like a broken quarter wave antenna with two radials broken off, one bent down vertical and the coax radiating at mixed angles (depending on how you route it) at node pionts progressively less the further away from the antenna. If you are going to leave out the choke, you would be better to add two more radials all bent down at around 45° and route the coax vertically down. The dipole antenna is a ballaced antenna, your coax on its own is not.

Russia?

Definitely not Mr Spoon.

Hi. My two cents for the putting the center conductor to the top when vertical. This way it maybe coupling to the ground better. I could imagine that you get a boost from the signal that bounces off the ground that way. HF vertical were explained to me that way. Cheers for the video. 73 de M/DL1FAB/m Node: FABm and FABp

Dear god 😅 ehy not get a sma and solder the core wire there and the gnd to grn and use actual 2.4ghz antenna 😅

Thumbs up

Thanks for the video.

Very interesting. Thanks for the video.

Thanks for the video, I will definitely give this a go

Thanks for sharing. I did something similar for a few non-LoRa Heltec dev boards (WiFi 32kit) that I am using for OWM weather data. Was having trouble connecting to WiFi. The pcb antennas are poor at best. I am also using a wire length of about 31mm.

Did I miss the dimensions. Would be useful.

Guessing you put this up vertically? Have you tried horizontal to see what effect it has? Would have been good to see your final set up. Thanks for the vid

Great !! 👍👍 Best 73 from Normandy France. Jacky 14FRS119

Nice

Good sound!

Memories 😂

Thank you, I am considering a similar modification, because Bluetooth is not great either. What wire length did you choose?

So, 31mm with or without the soldered bit?

Thanks for this upload. Good info, well presented. Subscribed. Just one question: how long will a new, fully charged, 18650 battery last in a waterproofed box, outside in the cold?

That poor desk.

Nice video Paul well explained

I mounted a pigtail to attach a patch antenna (needed to get WiFi through the outer wall of my home) I also soldered a PCB edge SMA connector on instead of the flimsy IFL connector for the antenna. Plenty of ground plane under the white paint on both sides of the PCB to solder all 4 legs. An edge SMA with 1.7mm spacing fits nicely and the center conductor rests perfectly on top of the 0 OHM resistor on the signal line to solder on. would save you another 0.5 dB. I had to unscrew the display and flip it over to have room for the soldering iron, but it fits back on with the SMA connector. Now I also have a neat way to mount the Heltec in an enclosure, simply with the nuts on the SMA connector threads.

One idea, instead of screws, I have seen very small strong magnets used.

I’ve got a 15.2 FBI gain that I’m trying out on Meshtastic, 915 mhz in the USA.

Greetings From Aberystwyth , Wales You Have A New Subscriber ! I Hope To Get A LoRa Set Up Soon ❤

Newbie question. Why is the insulation left on the red and black cables? Would have thought it would insulate the copper from the incoming signal?

Nice and simple ( you should mention) that this is a Dipole build in the video title.. 👍 ..73s

Brilliant video all I am in Daventry Northants and 2metre, s is dead round hear I call on thar quite often

I don't have the "Edit Groups" only the "Add Groups" Any idea why this is?

what is this sorry total noob here

Those take out units simply scream for a solar panel. There's an electronics shop in Cricklewood that sells a solar panel with built in Li-ion charger board.

Isn't it the case, that because this is fed with coaxial cable which terminates at the radio end with a grounded shield, that this isn't really a dipole? This is a monopole in the vacinity of a grounded wire. The grounded wire is stuck at 0V because, well, it's grounded. This means that the grounded wire can't radiate as there is no change in voltage. To make this a dipole, with two radiating elements, a balun is needed. No?

Brilliant...💯💥👌

The first picture looks very much like Worksop Radio Club, Glad your well Paul!

My node is not on the list (ENOT), as there is a big hill in the way down here in the east/middle of Nottingham. Might have a go at making my own antenna. Never made one at all. Would having multiple up-pointing elements and multiple ground-pointing elements make it a 'better' antenna, so sort of multiple di-poles wired to the same bit of coax?

Nice!!!! - I'm i right thinking that the wavelength should be either 35 or 34cm, right?

Me too, NC2 Loft

Wow and wow my loft needs one of these. Im on that list. COA1 COA2

Yay KARL G1YPQ

👍🏻

I have no audio on my phone speaker it only comes through my earpiece on my phone… any idea?

When you need a good anchor to stop it blowing over never neglect the value of a big battery, even a lead acid battery. You could also take gaffer tape and use a local big rock.

Thanks for the interesting video.... How do you get the signal strength bar of other nodes visible?

Correct me if I'm wrong but if your node shows up on the mesh map that means you're connected to the Meshtastic MQTT server and when texting others on the public channel you're really communicating across the internet. That defeats the purpose of the radio device, doesn't it?

Just need a solar panel and you could sneak one of those into a tree up there. Any idea what sort of size panel you would need?
