Title: Channel Master Offset? Post by bman040 on Dec 5th, 2007 at 3:01pm
Hi, was wondering if anyone knows the exact offset of a channel master 1.2m dish. I believe it to be similar to a 1.2m andrews class II as it has the 2 metal beams that support the dish on the back side. I couldn't find any part numbers or anything else to identify the dish other than its a channel master, and its 1.2m.
I'm trying to set my precise elevation in order to aim at W6, but my AZ/EL mount is in pretty bad shape (it has a slight warp to it) so I don't trust the elevation scale. Thanks, Brendan PS - anyone know a place that sells replacement AZ/EL mounts? |

Hi,
The offset angle should be 22.6 As you may know Channel Master antennas now produced under name of Andrew. Best regards, Huseyin |

22.6 is the angle for 1.8 meter. Possibly around 17 for 1.2.

Documentation Andrew-antenna-123-manual.pdf (1.5 Mbytes pdf file size) for Type Class I and II 960/123 0.96/1.2m says:
Type:123 Class I and II 1.2m 16.97 deg offset Type:960 Class I and IIĀ 96cm 15.4 deg offset The Class II Andrew antennas have short rear side struts. . These struts need to be adjusted to correct any dish distortion. Make sure the front rim of the dish is flat to 1.3 mm. Use tight fishing line up/down and across. Best regards, Eric. |
