Yuri, you don't have to disconnect the shields. All you need is to shorten 
the inner and outer conductor if the phaseline is about 80°-100° (electrically) 
long or have an open feed line for 170°-190°.

You do if you want the triangular array perform the way it is supposed to 
work with WX0B stackmatch. It can work as two driven elements fed in phase with 
third as reflector (frequency shifted by open coax stub/feedline) or as one 
driven element with two similar reflectors, giving 6 directions. In theory. In 
practice, it sucks, no pattern, dummiest three element omnidirectional "array". 
If you isolate the reflecotrs coax shields from the phasing unit, then it 
works. That is, with Stackmatch. Other phasing system will work differently.
