indicator of the |
|

|
|
|
|
antenna "Q" and what to expect with with stacking
and wet weather. |

of the antenna |
|
|
|

This combination of software provides excellent accuracy. Segment

|
|
|
|
|
|

Temperatures now adjustable to Tsky=27 Kelvin. Tearth: Rural = 460K

6. All stacking dimensions EXCEPT those marked with a "*" and "#" are |
|
|
|
|
|
|
|
|
|
|
|
calculated from the DL6WU stacking formula: |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
D = W/(2* sin(B/2)) |
|
|

|
|
D = stacking distance,vertical or horizontal |
|
|

|
|
|
W = wavelength, in the same units as D |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
B - beamwidth between -3dB points. |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Use vertical beamwidth for vertical stacking (as above), |
|
|
|
|
|
|
|
|
|
|
|
|
Use horizontal beamwidth for horizontal stacking. |
|
|
|
|
|

|
|
|
|
|
|
|
|

|
|
|
|
|
|
|
|
|
|
|
