Test Results
This page collects 5 independent VSWR tests of the Molex PCB ISM Dipole, measured firsthand by the Mesh community (NB2E, KG5HZC). Every nanoVNA sweep is charted below and downloadable as a Touchstone (.s1p) file. Best measured VSWR is 1.22:1.
Test #1
VSWR Measurements
902MHz
VSWR: 1.220:1
915MHz
VSWR: 1.551:1
928MHz
VSWR: 1.820:1
Notes from test
Antenna Flex PCB measures 100mm x 16mm and has a 50mm long micro coaxial cable terminated in a u.FL connector. Being a dipole the antenna exhibits a low VSWR and performs well regardless of orientation and without need for a ground plane. Three other part_numbers (206764-0100, 206764-0150 and 206764-0200) are available with longer attached coaxial cables (100mm, 150mm and 200mm).

Test #5
VSWR Measurements
902MHz
VSWR: 374.480:1
915MHz
VSWR: 235.536:1
928MHz
VSWR: 197.290:1
Resonant point: VSWR 74.243:1 at 946 MHz (101 points measured).
Notes from test
Adhesive-mounted flat against metal, which severely detunes the dipole and produces a very high VSWR across the band.
