 They claim it is just a touch better than LMR-400, although a random youtuber tested them and found the loss on the Hyperflex to be much more than specced, and the LMR-400 to be closer to its datasheet.
+Hyperflex 5: ~ 24dB / 100m insertion loss. So looks quite usable for a connection to a masthead radio.
 N connector loss: probably around 0.15dB. SMA similar. ~0.1 to ~0.2dB.

+Cable that came with small LoRa aerials, marked T240. About 0.5dB loss including adapters to N type. Diameter more like 0.230 in, but probably an LMR-240 copy.
