Coles County, Illinois | I've had a centerline 220 for two years and was disappointed with it's accuracy. So I ordered a Gilsson replacement antenna to try to improve accuracy. After reading about "convergence" time I decided to remain still for 15 minutes after power up before moving the tractor. I then mapped an S type line with one wheel of the tractor along the side of the road for 1/2 mile. The system worked great. For an hour I went back and forth at 6 miles an hour and the unit showed me dead on for 55 minutes out of the hour. The other 5 minutes it was only off a max of 1.6 feet.Should I have been waiting before moving all along or was the new antenna the fix I needed?TeeJet's literature only says it takes awhile before maximum accuracy is achieved it does not say anything about remaining stationary. | |
