Did you bust, break or otherwise buck up your ipex cable?  No worries i got you.

I stock 3 main lengths.
 
30cm (11.8 inches)
60cm(23.6 Inches)
90cm(35.4 Inches)

These are specifically for the Flipper Range Extenders and the Generic Extenders.  The length shouldnt affect the range too much, however you will be limited by the power output of the reader you are attempting to extend the range from.  These all have been tested to work well with the Flipper Range Extender with Card Antenna or with the Small Antenna.
