@HopelessDemigod I was definitely thinking of a smaller antenna :)
The #meshtastic #yagi is the size of a dinner plate, and connects to a few small boards.
Right now it's all on a desk pointing out a window. For a better view, the antenna needs to be outside on the patio. Maybe 3 meters of coax to connect my desk to the antenna.
#LMR600 would work, but it is also 0.6 inches diameter. The radio would almost fit inside the cable.
I should probably describe this as patch cable, given the short distances needed.

(reposting public, rather than quiet)
#HamRadio question: What types of #RF cable to buy and from where.
Low power < 1 watt
700 M to 5Ghz typical
DC to 6G sometimes.
Low loss is nice
50 ΩSpecific uses
1) making #antennas with matching or stubs.
Indoor and outdoor.
900 mhz #yagi
900 mhz folded #dipole
2) connecting antennas on patio to indoor radio.( 900 mhz, UV / weather resistant outdoor, fire resistant indoor. Possibly flat cable at door. Lightning arr.)
3) connecting boards together indoors (filters, amps, SDR, etc)
What I think that requires:
5 feet of moderately stiff cable for making antennas, #LMR 240/400 or equiv?10-20 feet of low-loss outdoor cable (not buried)
1-2 feet of thin / flat cable to pass around door.10-20 feet low-loss indoor cable. Fire resistant?
10 feet thinner flexible indoor cable to interconnect boards.
Tools for cutting & crimping. SMA, RPSma, but ideally also other types (TNC, N, maybe BNC, maybe ufl)

📡 Ah, yes, the granddaddy of all #antennas that no one asked for! Finn spent a decade constructing this colossal contraption in his backyard—because nothing screams midlife crisis like a 32x17 #Yagi monstrosity. 🤦♂️ Now he can talk to the moon while the rest of us are stuck debating if we should upgrade our Wi-Fi routers. 🌙📶

Reacquainted with #Buddipole 2 Element #Yagi setup for Six Meters and worked some #FT8 and tried some SSB. Just might try upcoming #AmateurRadio #HamRadio #ARRLVHFcontest. Might make it interesting and operate #QRP

I grew up listening to shortwave radio. I learned how to make antennas too. The proper length of antenna and electrically shortening or lengthening it with a capacitor or inductor. I would also learn how to take a #balun and make covert directional and #yagi antennas, something that might be very important if signals are jammed during a total fascist takeover. Cable, connectors, and makeshift insulators and RF iron cores, stocking up on these DIY antenna parts might be quite useful during the dark days ahead. Also, learning #MorseCode never goes out of style.

@finn #meshcore #diy #yagi #antenna
Danke. Ja, brauch nur noch einen neuen Stock ... <hüstel> ... Mast. Da werde ich das komplette Node mit Solarmodul und Tupperbox mit Akku und MPPT-Laderegler an den Stock ... äh ... Mast anbringen.
Aktuell teste ich auch die 6dB größere Sendeleistung des Heltec V4 aus. Heute im Überreichweitenwetter gingen tatsächlich mehr als 9 von 10 Nachrichten beim ersten Versuch raus und erreichten das Ziel. Der Rest dann beim 2ten oder 3ten Sendeversuch.
Soviel gechattet hab ich noch nie über Mesh. Ausserdem hilft es natürlich, dass Meshcore gerade regelrecht explodiert. Bei dir im Norden ist ja Kiel neben Hamburg vorne mit dabei.

#Meshcore #Meshtastic #lora #DIY #Antenna #Yagi
So. I was still not really nice with my last yagi antenna, which I have built lately.
I have chosen another build, which I found on printables.
This one:
https://www.printables.com/model/979820-10db-eu-and-us-lorameshtasticism-pe5i-yagi-antennaAfter several hours of printing, it's finally ready. It was hard to tune it properly. Best I got SWR 1,21 and impedance of 59+j3 Ohm. Not what I hoped to get. But I installed it.
I think that the link to my next meshcore repeater improved with more than 4 dB. But I have to check it over time.
