Yes, adding shielding foil to cable right up to the connector would help, be sure to use the insulating tape to cover it as you do not want the possibility of the bare metal foil coming in contact with any other electronic circuits. I do not see any benifit in adding shielding down the arms. The GPS is in the center of the top shell and the factory shield is all that is needed. it's the GPS cable that seems to be the issue. those of us that simply routed the cable under this shielding instead of over it have seen significant improvement in GPS reception. Also a Biggie in GPS reception, knowing what satellite's are visible and the K-Index as mentioned in other posts. I have GPS Plan on my iPhone, this tells me how many satellite's are overhead based on my location any time of the day. Doesn't matter what you do to your Phantom, it will only see satellite's that are above your location wether it's 4 or 12. for me right now, peak satellite coverage is 10;30am-12;00am with 11, the low is at 4:00pm-6:00pm with 5-6. Fliers think poor satellite lock is bad GPS reception, Yes and No. it is dependent on what is available overhead and your GPS receiver. i found that when my app was saying i had 10 satellite's overhead, my PV2+ was only seeing 6-7. after moving GPS cable under factory shielding i was consistently getting full lock on all visible satellites overhead. Get the APP and know your skies. The number of available satellites varies throughout the day for any given location. All we can and are trying to do is make the GPS receiver be the best it can be so we can lock in all available satellites. Like I said above, I don't believe there is any benefit in shielding the arms, there is nothing there GPS wise and the factory shielding over the GPS is sufficient. A co worker and i have identical PV2+ machines and he did the full foil treatment and i only moved the wire to under the factory shielding and we consistently get the same satellite lock so I don't see any bennifit to adding the additional foil shielding. I am going to work on grounding and shielding the cable better. One thing i did find when I opened up my machine was that the factory shielding was not stuck down very well, it was stuck to the GPS but loos around most of the edges, after I routed the cable under, I made sure it was firmly stuck down all around with no gaps.
Hope this helps.
