| Description: Inside the ENVI is a piece of insulated wire that acts as a receiving antenna, connected at one point to the circuit board it wraps around the casing in a U shape. The goal of this hack is to see if we can improve the range and reliability of the receiver by passing the antenna through a small hole at the top of the casing to the outside of the case. I would not recommend cutting or extending the length of this wire as they are normally cut to a length suitable for the frequency and any changes in length may result in less reliability.
Steps: Separation of the case: Care must be taken to separate the two halves of the LCD casing, they are snapped together at six evenly spaced points along the left and right sides of the LCD housing. Using a sharp blade you can start the casing joins in a position that is less visible when assembled, some marks may result at the point in which you start to separate the casings. Once you have inserted the blade into the casing seams you can use a small blade screw driver to run along one side of the case to separate one side and then the other. Once the casing is separated, I would not recommend removing the circuit board from the front half of the casing, this may result in problems to the connections to the LCD display. Locate the antenna and guide it up vertically to the top of the case and mark a position on the case where a small hole can be drilled to guide the wire through. Drill a small hole, just large enough for the wire to pass through and clear any plastic shavings. I suggest that the hole is best suited in the black part of casing. Pass the wire through the hole to the outside of the case and try to make it as vertical as possible. Snap the two halves of the cases together ensuring that you have not left any plastic shavings behind that may rattle around the case. Results: This modification has resulted in improvements receiving distance by about 7 meters (in doors) and more noticeably less problems with the occasional signal dropout. |
