An antenna feed angular alignment tool for an antenna feed and method of use. The tool having a body with a bore between a first end and a second end; a capsule, retained within the bore, having a first material and a second material enclosed within a cavity of the capsule. Coupling feature(s) integral with the body, proximate the first end are configured to rotationally couple with the antenna feed. The first material and the second material having different densities are movable within the capsule, indicating when the capsule and thereby the tool are aligned with a horizontal plane.

The invention claimed is: 1. An antenna feed angular alignment tool for an antenna feed end, comprising: a body having a bore between a first end and a second end; a capsule, retained within the bore, having a first material and a second material enclosed within a cavity of the capsule; and coupling feature(s) integral with the body, proximate the first end, configured to rotationally couple with the antenna feed end; the first material and the second material having different densities; the second end also provided with coupling features; the coupling feature(s) of the first end and the coupling feature(s) of the second end are configured for coupling with a first antenna feed and a second antenna feed, the first antenna feed and the second antenna feed having different antenna feed diameters. 2. The tool of claim 1, wherein the first material is a liquid and the second material is a gas. 3. The tool of claim 2, wherein the liquid is luminous. 4. The tool of claim 1, wherein the capsule is positioned with a capsule longitudinal axis normal to a bore longitudinal axis. 5. The tool of claim 1, wherein the coupling feature(s) are protrusions projecting inward from the inner diameter of the bore. 6. The tool of claim 1, wherein the coupling feature is a flat provided in the circumference of the body. 7. The tool of claim 1, wherein the second end is provided with coupling feature(s). 8. The tool of claim 7, wherein the coupling feature(s) of the first end and the coupling feature(s) of the second end are configured for coupling to the antenna feed at an angular orientation 90 degrees apart. 9. The tool of claim 1, further including indicia on the capsule arranged to indicate when the first and second material within the capsule are oriented such that the capsule is parallel with a horizontal plane. 10. The tool of claim 9, wherein the indicia is arranged on either side of a midpoint of the capsule. 11. An antenna feed angular alignment tool for an antenna feed end, comprising: a body having a bore between a first end and a second end; a capsule, retained within the bore, is positioned with a capsule longitudinal axis normal to a bore longitudinal axis, having a liquid and a gas enclosed within a cavity of the capsule; and coupling feature(s) integral with the body, proximate the first end and the second end, configured to rotationally couple with the antenna feed end; the coupling feature(s) of the first end and the coupling feature(s) of the second end are configured for coupling with a first antenna feed and a second antenna feed, the first antenna feed end and the second antenna feed end having different antenna feed end diameters. 12. A method for angular alignment of an antenna feed end, comprising the steps of: rotationally coupling a tool provided with a capsule filed with a first material and a second material to the antenna feed, via at least one coupling feature of the tool; the first material and the second material having different densities; and rotating the tool and thereby the antenna feed end until the first material and the second material within the capsule are oriented within the capsule to indicate the capsule is parallel to a horizontal plane. 13. The method of claim 12, wherein the indication that the capsule is parallel to the horizontal plane occurs when the one of the first material and the second material having the lowest density is situated at a midpoint of the capsule.
