Narrative:
Our drop zone lies adjacent to a restr area. On the final jump run leg, we have to fly parallel to the restr area. Normally, we can see ground landmarks that provide a good indication of our ground track and proximity to the restr area's border. Today, however, there were clouds that, while clear over and upwind of the drop zone, lay below us for a few mi on the final leg. To help us remain clear of the restr area on days like this, we use a handheld GPS with an antenna that's attached to the window. Which navigating, unbeknownst to me, the antenna fell off the window. The GPS became inaccurate and I inadvertently drifted into the restr area. Once clear of the cloud layer, I realized my mistake and immediately corrected. I was in the restr area for about 3 mins. I later called cerap and explained my situation. The GPS antenna has since been attached more permanently to avoid similar problems.

Title: BEECH 100 KING AIR PLT INADVERTENTLY ENTERED RESTR AIRSPACE DUE TO LOSING THE HANDHELD GPS ANTENNA OFF THE COCKPIT WINDOW RESULTING IN NOT AN ACCURATE FIX OVER THE GND.
Narrative: OUR DROP ZONE LIES ADJACENT TO A RESTR AREA. ON THE FINAL JUMP RUN LEG, WE HAVE TO FLY PARALLEL TO THE RESTR AREA. NORMALLY, WE CAN SEE GND LANDMARKS THAT PROVIDE A GOOD INDICATION OF OUR GND TRACK AND PROX TO THE RESTR AREA'S BORDER. TODAY, HOWEVER, THERE WERE CLOUDS THAT, WHILE CLR OVER AND UPWIND OF THE DROP ZONE, LAY BELOW US FOR A FEW MI ON THE FINAL LEG. TO HELP US REMAIN CLR OF THE RESTR AREA ON DAYS LIKE THIS, WE USE A HANDHELD GPS WITH AN ANTENNA THAT'S ATTACHED TO THE WINDOW. WHICH NAVING, UNBEKNOWNST TO ME, THE ANTENNA FELL OFF THE WINDOW. THE GPS BECAME INACCURATE AND I INADVERTENTLY DRIFTED INTO THE RESTR AREA. ONCE CLR OF THE CLOUD LAYER, I REALIZED MY MISTAKE AND IMMEDIATELY CORRECTED. I WAS IN THE RESTR AREA FOR ABOUT 3 MINS. I LATER CALLED CERAP AND EXPLAINED MY SIT. THE GPS ANTENNA HAS SINCE BEEN ATTACHED MORE PERMANENTLY TO AVOID SIMILAR PROBS.
