K4ZXX MOBILE a Heltec V3 Nod
e (semi-monitored) in my service vehicle using a Bingfu Lora Antenna 915mhz 3dbi Helium Miner Magnetic Base HNT Omnidirectional Antenna
915mhz 3dbi Helium Miner Magnetic Base HNT Omnidirectional Antenna Features;
- 【Built-in Pure Copper】 – The main body of the antenna is made of pure copper material, which has more excellent gain performance
- 【Magnetic Base】 – 6 cm/ 2.36inch Strong magnetic Base, for better reception, please try a position with a better view, somewhere like near the window.
K4ZXX BENCH is a Lillygo T-Beam S3 Supreme (semi-monitored), a basic MQTT node on the workbench
I was a big fan of the S3 early on but recently had some bad luck with a few of the Lillygo nodes and have since moved over to the Heltec V3 which seems to be way more stable. I have put about 200+ nodes into the wild through online sales of solar nodes and drone nodes.
PowerNode (un-monitored) is a Heltec V3 at the QTH using a Bingfu Lora Antenna 915mhz 3dbi Helium Miner Magnetic Base HNT Omnidirectional Antenna on a 30′ mast and a LoraOffGrid 4 Watt Amplifier / Booster
The PowerNode has about a 40Mile Radius of LoRa Service (extensively tested and verified).
LORA Amplifier Features:
915MHz 36dBm Wireless Power Amplifier (RF OUT) / Reception Boosted Gain: 28dB±1 (RF IN)
Description
The Lora Off-Grid Amplifier / Booster was developed for 915MHz frequency band which have special requirements for signal transmission distance and connection stability.
For example, wireless data acquisition systems (LoRa) products and low-power wireless products within the 915MHz frequency band can legally use this Amplifier / Signal Booster to increase transmission distance.
Key Features
20X the power, improving the link quality and coverage of certified devices.
2dB ultra-low noise
12v operating input
Simply plug and play, no software is required
For use with all LoRa Devices
