Super lowcost extra WiFi gain for Router, AP and USB dongle. *
1. Open the template (WindSurfer-Template.jpg) in MS Paint or something like that and resize if desired.
Ensure that you keep the square on the diagram square.
2. Print image on business card stock or acetate (document protector).
3. Cut it out and open the six slots of the reflector with scissors or a hobby- or break-knife.
If the used paper is too thin, make a ‘copy’ of it on thicker cardboard.
4. Glue tin foil to the back side of the reflector surface. When using also a copy on thicker cardboard,
glue the tin foil on the copy of the reflector and than glue them together and glue also the copies
of the holder together. Use a good kind of glue like Bisonkit transparant.
5. Cut the crosses in the holder with a hobby- or break-knife.
6. Assemble by placing the six tabs of the holder in the six slots of the reflector. Fold the tabs after
placing and fix them with glue.
7. Place the assembly on the WiFi antenna and aim the reflector in the direction of the ‘target’
(to WiFi client, Router or AP) to get maximum performance.
Note: If printed at the download size you will see about 6-9 dBi of gain. If you double the size of the
image before you print it you will see about 9-12 dBi of gain. If you place two reflectors on an AP or router
with two antennas you will see an additional increase in performance. *) Types
without external antennas can’t be improved this way, but a USB WiFi dongle with an external antenna can!
