Vector Network Analyzer 10KHz-1.5GHz
The Thinkstar NanoVNA-H REV3.4 is a portable vector network analyzer covering 10KHz to 1.5GHz. It targets radio amateurs and RF engineers who need a compact instrument for antenna and filter characterisation in the field or on the bench.
Battery Management and Direct USB-C Link
A redesigned PCB adds battery circuit management for safer operation and enables a direct Type-C to Type-C connection to a smartphone, removing the need for an OTG adapter. PC control software allows touchstone SNP file export for use with radio design and simulation tools.
Shielded Enclosure with SMA Port
The unit ships in a protective, dust-proof shell case with a metal shield that reduces external interference and improves measurement accuracy. A single SMA connector provides the RF interface, while the 54mm by 85.5mm by 11mm enclosure weighs 63 grams for easy transport.

Questions about this item
Will the SMA connector on the NanoVNA-H REV3.4 need periodic replacement after repeated antenna measurements?
The SMA adapter is a standard connector; treat it like any RF SMA port — inspect the threads and centre pin for wear, and replace only if mating cycles degrade the return loss beyond the <1.1 port SWR spec.
What measurement dynamic range limit appears first when sweeping continuously from 10 kHz to 1.5 GHz?
Dynamic range drops from 70 dB (50 kHz–300 MHz) to 60 dB (300–900 MHz) and 40 dB (900 MHz–1.5 GHz), so the 40 dB ceiling at the top of the band is the first hard limit under sustained wideband use.
How much does the 2.8 inch TFT and RF front-end heat the enclosure during an all-day field session?
The 63 g unit draws modest power from its internal battery management circuit; the metal shield and compact 54 × 85.5 × 11 mm case dissipate heat passively, so the enclosure stays near ambient temperature during continuous operation.
