Human Factors; Procedure
I was the SIC and Pilot Flying on this Part 91 repositioning leg from BLM.  The Captain (the Pilot Not Flying) acquired the ATC clearance while I was starting the aircraft.  We received a clearance to proceed direct to DIXIE and then the CYN 226 degree radial at 11 miles.  As PNF; the Captain pulled out charts and tried to determine whether or not the 226 degree radial at 11 miles was a named fix or not.  He determined it was not; so he set up raw data for me as I taxied out for departure.  After departure; we flew the clearance as issued (or so we thought); but it turns out the Captain mistakenly entered the reciprocal of the 226 degree radial.  In other words; we hit the 11 DME fix northeast of the CYN VOR instead of southwest.  McGuire approach questioned us and I immediately noticed the error in NAVAID setup.  After some back and forth and clarification; we received a new instruction to proceed direct to ACY VOR and the flight continued normally.  The Captain and PNF definitely made an error in entering the flight plan; and I should have caught this error myself.  However; it is not company SOP for me to double-check his flight plan entries; and I was task saturated and did not notice the error.  Looking back on our clearance; both the Captain and I felt that it was unnecessarily complicated.  It would have simplified matters if we were cleared DIXIE CYN CYN226011.  With the clearance as it was; it was up to us to try and navigate between DIXIE and CYN226011.  Both the Captain and I have significant experience operating into BLM airport; and we both remarked on how frequently the clearances are unnecessarily complicated.  It is very difficult for us in our aircraft to navigate to unspecified radial/DME fixes.  While it can be done; I feel it would be in the interest of safety for McGuire to simplify their departure clearances when at all possible and eliminate the use of radial/DME fixes.
Corporate aircraft First Officer reported a track deviation error; with the clearance to a radial/DME fix cited as contributory. Reporter stated complex clearances tend to be the norm when operating in BLM.
