This sort of thing makes me dig out the manual. :-)
The STABS HH90 manual says to set the rotor elevation to latitude , and the Sadoun site installation calculator says the same thing. Are different brand motors configured differently ? I'm thinking of getting an SG2100 and I'd hate to walk into a trap. |
It is not a trap. I have a Sg2100 and it has dual scales. One is elevation and one is latitude. As Bill has stated when you are in the 40-50 range for both it can get a little rough if you are not paying attention. My elevation is something around 51 and my lat is 39. If I set using lat on the scale for elevation I will be way off. If I set lat on the lat scale and check the other side of the motor I will find it reads roughly 51.
I think you might be getting a bit confused with the terminology used. It could probably be worded as "Set the motor as so the indicator aligns on the scale equal to your latitude". Thus eliminating the word elevation from the statement.
Another issue you have here is Bill like myself and others have big dishes also. The terms elevation and declination are used when talking about a big dish. While the concept is the same I think we see it a bit differently than someone who is only accustom to a small dish and even more differently than someone with no dish experience and this being their first install.
