Since you made 2 dipoles, are you sure you put the 10 meter dipole up at 20 feet and are measuring it and not the 6 meter dipole? BTW, what does the 6 meter dipole show for SWR?
1) If indeed the 10 meter dipole up there,disconnect the coax at the antenna and place your dummy load on the antenna end of the coax and see if your 920 sees a low SWR at the shack end of the coax. Nothing like a bad piece of coax to ruin antenna experimentation. Measure it at 80 meters all the way thru even 6 meters if you can, just to see. 2) f you have another SWR/power meter put it at the dummy load end and see what kind of losses you have. Compare the transmit end power to the dummy load end power. If you have lossy coax, the SWR at the radio should be much better than at the antenna...which is a BAD situation, as it looks good but it is not. 3) Bring the antenna down to close to the ground so yuou can reach it. Use a very short piece of coax to connect the antenna feed point to the radio or your antenna analyzer.....Good? Still bad??? If bad then the antenna is a reactive dummy load. Start over.
