Need help setting KTI elevation and zenith adjustments

[Alan Rovner]

Hi guys, I have an old KTI dish I'm trying to restore and get back on the air. The documentation is very limited and has really tiny diagrams of where to adjust elevation and declination offset/zenith. Please look at the attached photos and let me know if this is where to measure angles. The elevation picture shows my angle meter on top of the mount, and I believe the other picture is showing the zenith adjustment down at the bottom of the dish. Thanks so much for any suggestions.

Alan, K7AR

Put it on the flat part of the elevation pivot. In between the pivot and the center plate of the dish.

Id say where you are measuring on the bottom photo wouls be incorrect unless that spar is not curved at all from the center of the dish. I usually use my digital inclinometer in the center portion of the dish on the back side. But its small enough to fit in there. Fatair always said take a 2x4 and lay it across the front edges of the dish and measure that way. I actually made a 2x4 that had a scarp piece nailed on the end so i could hang it on the front of my dish but figured out my inclionmeter fit on the back of the dish and never used it. However where you are measuring in the top photo is where i measure my dish. Wherever you do measure make sure you write it down and always measure from those spots when you tune up your dish.

Actually i just looked at my measurements and i measured and recorded both places on the outside like you have yours in the top pic and 90* over between the dish and the mount.

I recall a pretty good thread that might help you understand where to measure and how to calculate your angles.
