Notes from test

Since there's no published datasheet for this antenna I can't say whether the abysmal SWR plot is within manufacturer specification or not. This antenna is offered by Seeed Studio as a higher gain antenna for the helium network, but at a 3.394:1 SWR would exhibit 5.275dB of return loss and 1.529 dB of mismatch loss (making their claimed 5dBi gain impossible.) If used in the 860-870MHz range where the VSWR is > 8:1 it would surely cause equipment damage.
