Hello! I'm trying to align an Andrew (Channel Master) antenna in Ku frequency, to Intelsat 805 satellite. It is a 1.2 m RxTx Class I Antenna System (Type 120TX), with a LNB model NJR2144HT. I'm connecting it to a satmodem Shiron irg40, which I've already used with another antenna and worked fine.

The first antenna had 2.4m, and a fine adjusment in azimuth and elevation. The 1.2m antenna doesn't have fine adjusment on azimuth, only on elevation, with a 10 to 90 degrees range.

I'm located in Bogota, Colombia with parameters: 4.6961 North and 74.0636 West. I aligned the first antenna with elevation: 67.6 (without the offset) and azimuth: 103.7

My question is that, the first antenna has an offset of 22 degrees, and it was very important in order to align it, but I don't know if the Andrew antenna has an offset too, so I don't know if that is the problem with its alignment (it doesn't lock to satellite).

Can anyone please help me with this problem?

Thank you....

As far as I remember, Andrew has two or even three 1.2m models, one of them has indeed offset of 22 degrees. Also, do you have any spectrum device or monitor? And last thing, when you point your antenna, don't forget that in Bogota you are 2000m closer to the stars Q tengas Suerte!
