Exactly. The antenna in the paddle is a patch. One way to do it, would be to mod the circuit in the receiver, and add attenuation, say 6-10dB, and try that. It will be more critical of aiming, but may take out the interference. There are loop yagi designs on the web that will help make it more directional. -- Dave's Engineering Page: http://www.dvanhorn.org I would have a link to http://www.findu.com/cgi-bin/find.cgi?KC6ETE-9 here in my signature line, but due to the inability of sysadmins at TELOCITY to differentiate a signature line from the text of an email, I am forbidden to have it. -- http://www.piclist.com#nomail Going offline?
