Realizing that slots in a plane (ground, for example) are a bad idea, is it ever acceptable? Here's something some info from Henry Ott: http://www.hottconsultants.com/techtips/tips-slots.html He says "don't", but then says well, if you do so, don't allow any lines to cross them. OK, I'm good by that. But, don't slotted planes give rise to eddy currents around the aperture (even if nothing ever crosses the slots)? gene ------------------------------------------------------------------ To unsubscribe from si-list: si-list-request@xxxxxxxxxxxxx with 'unsubscribe' in the Subject field or to administer your membership from a web page, go to: //www.freelists.org/webpage/si-list For help: si-list-request@xxxxxxxxxxxxx with 'help' in the Subject field List technical documents are available at: http://www.si-list.net List archives are viewable at: //www.freelists.org/archives/si-list Old (prior to June 6, 2001) list archives are viewable at: http://www.qsl.net/wb6tpu
