Beerman Posted February 8, 2007 Report Share Posted February 8, 2007 ROFLMAO! Very good imagination and I prefer the BBQ Pringles. Routers won't last long I bet. I have a Linksys G Speedbooster and I'm using a hacked firmware that allows me to crank up the power a bit but I'm only about 30% as cranked as it will allow me because I don't need it more than that and, I don't want to be buying routers every 6 months. I also purchased some high gain antennaes because I'm in a 2 story home and I get very, very good reception all over. If I wasn't encrypted, my neighbors 2 doors down could use my wireless (of course, I don't broadcast my SSID). I know you're not serious about this but it does make one wonder. Might be something to try when you are ready to say goodbye to some of your older equipment. Link to comment Share on other sites More sharing options...
gi7omy Posted February 8, 2007 Report Share Posted February 8, 2007 Actually - that lashup is very similar to some diagrams I have in my well-worn VHF-UHF manual ( home brew parabolic reflector and all). Nothing new in it to be honest (and my manual is at the very least 10 years old ) Now if you REALLY want good gain - use a parabolic saucepan lid or a dustbin/trashcan (if you can find one of the old metal round ones around) Link to comment Share on other sites More sharing options...
REDWAGON Posted February 8, 2007 Report Share Posted February 8, 2007 Yeah---Just use this simple standard parabola formula: Ax^2 + bxy +Cy^2 + Dx +Ey +F = 0 To bend that old trash can lid into the parabolic shape of your choice Frank... Link to comment Share on other sites More sharing options...
gi7omy Posted February 8, 2007 Report Share Posted February 8, 2007 Try this - all you need work out is the focal point of the parabola D = Diameter, c = depth of the curved part at centre f=DxD/16c Link to comment Share on other sites More sharing options...
