Meshtastic radio FAQ Questions, answered

The Nephilim NPH-1 is a rugged, CNC-machined Meshtastic radio designed for long-range, off-grid communication. It uses LoRa mesh networking to send and relay encrypted messages without cell service or Wi-Fi.

The NPH-1 is a persistent node: a CNC-machined aluminum enclosure, 22 dBm output, dual external antennas for LoRa and Bluetooth, and a built-in battery that runs for weeks. The EDICT-HP is a high-power radio: a 30 dBm (1 W) RF platform in an MJF nylon shell with aluminum top and bottom plates, fully silicone potted, powered by standard Baofeng UV-5R battery packs you can hot-swap in the field.

Our devices are engineered for real-world field use. The NPH-1 is machined from solid aluminum with dual external antennas, long battery life and weather-resistant sealing; the EDICT-HP pairs a purpose-built 1 W RF platform with a potted, reinforced chassis. Both are built for durability, reliability and consistent performance in harsh environments.

The NPH-1 is water- and dust-resistant, internally tested to IP67: the Nephilim series uses sealed gaskets, O-ring interfaces and a robust enclosure design, and its housing is CNC-machined from 6061-T6 aluminum with thick walls. Neither radio has a published drop or impact rating yet. The EDICT-HP is fully silicone potted after assembly, which seals its electronics in silicone.

Our radios use standard SMA connectors and support a wide range of external antennas, from high-gain whips to compact options for tight installations. Choose antennas based on range, size or application.

Yes. Our radios run Meshtastic or MeshCore firmware (Reticulum on the NPH-1; the EDICT-HP Reticulum build is coming soon) and pair with both iOS and Android apps. We ship units ready to use, and you can update firmware at any time through the app or USB-C.

Range varies with terrain and antenna selection. In open environments users commonly reach several miles, while dense urban or forested areas reduce distance. The mesh extends coverage automatically as more nodes join.

The NPH-1 includes a high-capacity rechargeable Li-ion battery. Typical runtime is 2–4 weeks per charge, depending on reporting intervals, relay usage and power settings. The EDICT-HP runs on Baofeng UV-5R packs, so runtime depends on the pack and you can carry spares.

Not on the NPH-1: its 5200 mAh battery is built in and not user-removable, so email us if it ever needs service. The EDICT-HP uses standard UV-5R packs that swap by hand.

Yes. Messages are encrypted by the Meshtastic or MeshCore encryption layer. Each channel uses its own key, so only authorized users can read transmitted data.

Absolutely. Our devices include mounting points and work with multiple mounting systems, including our high-strength zip-tie mounts and other modular accessories.

Email Benjamin@deltaplusproto.com. Include which radio you have (NPH-1 or EDICT-HP), your order number if you have one, and the firmware you are running.

EDICT-HP firmware builds for Meshtastic and MeshCore, and the DeltaMeshFlasher desktop tool for Windows, macOS and Linux, are on the Downloads page. A Reticulum (RNode) build for the EDICT-HP is coming soon.

No. The EDICT-HP runs on standard Baofeng UV-5R battery packs and uses an SMA antenna; neither is included.
