The cable alone from the pigtail acts as an antenna.
Since no test was done before the mod, a test after wouldn't give enough info.
I can give signal noise levels with and without an ant attached if you like.

You could even make a 2.4 GHz field strength meter to better measure your antennas:

this hack is very very useful for the wardriving with n810 !

The cable is shielded, the shielding is soldered to another point.
Someone have someplace they can host the High Res pics??
I can email them.

I don't think that is real, it could be some kind of artifact.
Try to do some measurement of signal quality, like transfer speed at a given distance, signal/noise levels, rx/tx errors, ...
At least you should have a 1/4 wave antenna, otherwise there are no impedance match, and that means reduced signal transmision and power reflection back to the transmitter (which could overheat).
