TESTING INCLUDING READ RANGES
THESE ARE DESIGNED AS EXTENDERS NOT REPEATERS
However there are some noticeable range improvements
SMA Testing
Baseline ( Flipper vs. xLED )
Naked = 10mm
SMA extender = 20mm
Baseline ( Flipper vs. FLEX)
Naked = 30mm
SMA extender = 30mm
JST Testing
The large,\ antenna is not designed for an xSeries, therefore it should be expected to work for xSeries, however it does work well for Flex implants
Baseline ( Flipper vs. xLED)
small antenna ~50% range increase
Naked = 10mm
Small antenna = 15mm
Baseline ( Flipper vs. FLEX)
20mm for flex on small antenna
30mm on large antenna
IPEX Testing
No testing carried out
TEARDOWN
N/A
JST, are keyed, Make sure you plug them in correctly and fully, when unpluging, do so carefully without applying pressure to the solder joints
SMA , ensure they are not loose, finger tight should be enough, or tighten lightly with a small spanner
