Heltec WiFi LoRa 32 V3.2 (863-928 MHz HF): antenna connection reference

Start with the exact board and revision. A similar product name does not establish the connector, regional radio variant or antenna path.

Documented antenna ports

Use the port intended for LoRa. The presence of a Wi-Fi antenna or a visually similar miniature connector does not make it a supported LoRa path.

Frequency scope

863-928 MHz HF variant. MeshMatch evaluates the selected operating frequency separately from mechanical connector mating. A matching connector can still lead to an unsuitable antenna.

Before ordering an antenna

1. Confirm the label or revision marking on your board matches this reference.
2. Identify the LoRa antenna port and whether an adapter is needed.
3. Check both ends of every cable, including the centre contact and miniature connector series.
4. Check the intended channel against the documented radio and antenna coverage.
5. Review enclosure clearance, mechanical strain and local operating requirements separately.

For an I-PEX connection, an unspecified series remains unknown. This reference does not infer cross-brand compatibility from the word IPEX. It also does not establish cable loss, RF performance, range, firmware support or legal operation.
