Station G2 - ~$109 (as of 2026-06-08) The Station G2 is the benchmark base station for MeshCore and Meshtastic networks. It delivers 36.5 dBm (approximately 4.46W) of TX power - substantially more than the 22 - 28 dBm typical of portable devices. A built-in LNA improves receive sensitivity, extending the effective range on both transmit and receive. Price is volatile; check the current listing on the official B&Q Consulting shop (shop.uniteng.com) or Tindie before buying. Station G2 Key Specs TX power: 36.5 dBm (4.46W) via integrated 35 dBm PA - note: this conducted level exceeds the FCC Part 15.247 1 W / 30 dBm conducted limit; lawful at full power in the US only under an amateur Part 97 license (with encryption off) - see FCC compliance note below LNA: Yes - improves receive sensitivity Power input: 15V USB-C Power Delivery (PD) - standard USB-A/5V chargers will not work MCU: ESP32-S3 (WROOM-1) Radio: SX1262 Display: 1.3" OLED Antenna: SMA connector; use a high-quality outdoor antenna Enclosure: Open board; requires weatherproof enclosure for outdoor deployment FCC Part 15 Note: In the US 902-928 MHz ISM band, FCC Part 15.247 limits conducted output to 1 W (30 dBm) referenced to an antenna of up to 6 dBi; with a 6 dBi antenna this works out to a derived 36 dBm (4 W) EIRP ceiling. The 36 dBm figure is a derived EIRP limit, not a flat standalone conducted limit. Antennas above 6 dBi require a dB-for-dB reduction in conducted power. The Station G2's 36.5 dBm conducted TX power already exceeds the 30 dBm conducted limit on its own, before any antenna gain - so it is not legal for unlicensed Part 15 operation at full power. Amateur radio operators using Part 97 authority may run higher power (up to 1500 W PEP under 47 CFR 97.313, subject to conditions), but Part 97 prohibits messages encoded to obscure their meaning - which conflicts with Meshtastic's default channel encryption - and requires a licensed control operator and station identification. Consult Part 15.247 and Part 97 rules and your antenna's gain specification before deploying. Deployment Considerations Mount at the highest practical point. Line-of-sight dominates range at 915 MHz - elevation matters far more than TX power. Use low-loss coax (LMR-400 or equivalent) for the feedline. At 36.5 dBm output, cable loss becomes significant. Every 3 dB of cable loss halves your effective radiated power. Pair with a 5 - 8 dBi omni antenna for broad coverage, or a Yagi for point-to-point backbone links. Remember that any antenna above 6 dBi requires reducing conducted power dB-for-dB under Part 15.247. The 15V PD requirement means you need a USB-C PD charger or power supply. Many laptop chargers work. For solar-powered base stations, you will need a 15V solar charge controller output, which is non-standard - most builders use a boost converter from a 12V battery. RAK WisBlock Base Station Approach An alternative base station can be built using a RAK4631 (nRF52840 + SX1262) on a RAK19007 base board, mounted in a weatherproof enclosure. This approach costs more upfront but offers modularity: you can add GPS modules, environmental sensors, or additional radios on the WisBlock connector system. The RAK4631 draws far less sleep power than the Station G2 (2.0 µA module sleep vs the ESP32-S3's milliamp-range sleep), making it more practical for solar-powered base stations without a boost converter. Note the RAK4631's bare SX1262 tops out at ~22 dBm, well below the Station G2's PA-boosted output. Siting a Base Station Consideration Guidance Height Greater height extends the radio horizon and clears terrain and Fresnel-zone obstructions, which is usually the dominant range factor - the benefit is not a fixed amount per height doubling. (Separately, in free space doubling the link distance costs ~6 dB of path loss.) Rooftop > hilltop > pole-mounted > ground level. Obstructions Buildings and trees absorb 915 MHz. Clear line of sight to the horizon is ideal. Antenna choice 5 - 8 dBi for omnidirectional coverage. Higher gain focuses the beam - avoid if terrain varies in elevation around the site. Antennas above 6 dBi also require a dB-for-dB conducted-power reduction under FCC Part 15.247. Lightning protection Use a DC-grounded gas-discharge lightning arrestor on the feedline. Ground the mast. 915 MHz / sub-GHz arrestors are inexpensive (often under ~$30, as of 2026-06-08). Power Mains power is preferred. Solar requires careful sizing for winter minimums. Fixed Infrastructure Node Hardware Selection Fixed infrastructure nodes - backbone repeaters, room server hosts, and long-term outdoor installations - have different hardware requirements than portable client nodes. Reliability, power efficiency, and maintainability are the priorities. Primary Hardware Candidates RAK4631 (nRF52840 + SX1262) The RAK4631 WisBlock core is the most popular choice for fixed infrastructure in 2025-2026: Current draw: ~17 mA in continuous LoRa receive (RAK datasheet), ~125 mA transmit at 22 dBm (SX1262 ~118 mA per Semtech, plus MCU). Sleep is ~2.0 µA. A ~3 mA figure would be a duty-cycled/averaged idle value, not steady receive. Average power: ~8-15 mA in typical repeater operation (estimate; actual average depends on RX duty cycle and traffic - mostly RX at ~17 mA with brief TX bursts and low-power sleep between) Advantages: Modular WisBlock system allows easy sensor/GPS/display add-ons; nRF52840 has excellent power management; SX1262 supports all required frequencies Form factor: Small enough to fit in an IP67 enclosure with a 18650 battery pack Firmware: MeshCore (REPEATER or Companion), Meshtastic LILYGO T-Beam Supreme (ESP32-S3 + SX1262) Good choice when WiFi/MQTT gateway capability is needed at a fixed site: Current draw: ~80-120 mA approximate whole-board current with ESP32 WiFi active, ~30 mA (WiFi off, LoRa only; depends on GPS on/off and CPU activity). Both are board-level estimates, not single datasheet values. Advantages: Built-in GPS, WiFi for MQTT bridge, USB-C, relatively large community Disadvantages: Higher power draw than nRF52 makes solar budget larger; ESP32 requires periodic watchdog resets in some deployments Best for: Gateway nodes with internet connectivity, sites with reliable grid or large solar panels Heltec HT-n5262 / HT-n5262M (nRF52840 + SX1262) Ultra-compact option for space-constrained installations: Current draw: Comparable to the RAK4631 (both are nRF52840 + SX1262): expect ~17 mA continuous LoRa RX, ~125 mA TX at 22 dBm, microamp-range sleep. Verify against Heltec's datasheet for the specific variant. Advantages: Extremely small form factor (the HT-n5262M is a 1.27 mm stamp-hole solder-down module for integration onto your own PCB). Note: the bare module does not include a LiPo/JST connector; a built-in battery connector applies only to a dev-board variant - confirm the variant you are buying. Best for: Discreet indoor deployments, installations with severe space constraints Hardware Selection Matrix Use Case Recommended Hardware Reason Solar outdoor repeater RAK4631 Lowest power, weatherproof WisBlock ecosystem Indoor backbone with internet gateway T-Beam Supreme WiFi for MQTT bridge (GPS is largely unusable indoors without sky view, so position tracking applies only to an outdoor/rooftop gateway) High-altitude remote repeater RAK4631 Low power essential for limited solar; reliable firmware Room Server host: RAK4631 or Heltec V3 running MeshCore Room Server firmware RAK4631 via USB serial Pi handles room server; RAK handles LoRa radio. Verify the supported host hardware and architecture against docs.meshcore.io Room Server requirements before deploying. Antenna Considerations for Fixed Sites Infrastructure nodes should use external antennas rather than the stub antennas included with most development boards: Omnidirectional (5-8 dBi fiberglass): Best for covering 360 degrees; mount at highest practical point Yagi/directional (10-15 dBi): Best for point-to-point backbone links over long distances; requires careful alignment. Note for unlicensed US (Part 15.247) operation: antenna gain above 6 dBi requires a dB-for-dB reduction in conducted transmitter power, so high-gain Yagis above 6 dBi must be paired with a correspondingly lower TX power setting. Antenna cable: LMR-195 or LMR-400 (minimize cable length to reduce loss). LMR-400 has ~1.3 dB/10 m (12.8 dB/100 m, 3.9 dB/100 ft) loss at 900 MHz per the Times Microwave datasheet.
