| 1. | One benefit was the high elevation angle of the DT machine gun.
|
| 2. | The barrel was clamped at two elevation angles only-45 and 75 degrees.
|
| 3. | This meant that the range, not elevation angle, was set on the sight.
|
| 4. | It quickly scans 360 degrees around the site on a single elevation angle.
|
| 5. | :: Azimuth and elevation angles are the lateral and vertical aiming angles respectively.
|
| 6. | Two sets of signals are broadcast at two different elevation angles.
|
| 7. | The curve labeled as bvp is the trajectory found by correcting the elevation angle.
|
| 8. | This meant that different guns needed a different elevation angle for the same range.
|
| 9. | To achieve the required elevation angle, various arrangements were used.
|
| 10. | There are a large number of reflectors on the ground at these elevation angles.
