Hello I came up on this two sites with the same pictures of feeding a cross yagi, but one says RHCP and the other one says LHCP: http://www.qsl.net/sv1bsx/antenna-pol/polarization.html : on the end off the page there are to pictures from a cross yagi, the last one LHCP and the previous one above it RHCP. The center conductor (+) is connected to the upperside at the rear dipole and on the left side at the front dipole. it is CCW when you look from behind, and the autor says RHCP. Now look at this one: http://www.dg7ybn.de/Building/xpol.htm : look at picture (2) by left hand circ pol. Assume you turn the antenna 45° clockwise and you will get the same picture as the one mentioned above(SV1BSX). This one also looks CCW from behind and the autor says LHCP. It is confusing when building home made antennas. I think both are LHCP... Best 73's Jerry,ON4CJQ
