Title: Inverted Dish Post by patmos on Mar 3rd, 2010 at 10:08am
I followed the good article on offset dish angle https://www.satsig.net/22-deg-offset-dish.htm
I understand that: Inclinometer angle = offset angle - calculated sat el angle. ( zero up for inclinometer). I used my iphone to check some already installed dish with clinonometer a free app. It proves good. But what is the inclinometer reading for an inverted dish, suppose I hold inclinometer the same way? I check a prodelin 3.8 m inverted ( sat el angle = 4.9). I get 25 deg ( zero up/down). I cannot figure out how it came to 25 (or 65 deg the other way). Thanks |
