- MICROWAVE PATH ANALYSIS
- LOTUS 123 WORKSHEET PROGRAM
- BY
- BRUCE V. ZIEMIENSKI
-
-
- PATHANA.WK1 is a Lotus 123 worksheet used to calculate a
- microwave path or system. The variables are for the most
- part entered in the text area above the calculation tables.
-
- To use this worksheet use Lotus 123 2.01 or higher or
- any compatible 123 clone such as The Twin. Enter your
- frequency and path elevations also other varibles such as
- Terrian and Climate Factors and Earth Curvature. For the
- Factors Such as Terrian, Climate and Earth enter the
- following from the TABLE below.
-
-
- TERRIAN FACTORS
-
- 4 = Very smooth terrian, including overwater.
-
- 1 = Average terrian, with some roughness.
-
- 0.25 = Mountainous, very rough terrian, or very dry terrian.
-
-
- CLIMATE FACTORS
-
- 0.5 = Gulf Coast or similar hot, humid areas.
-
- 0.25 = Normal interior temperate or Northern locations.
-
- 0.125 = Mountainous, or very dry locations.
-
-
- EARTH CURVATURE FACTORS (K FACTOR)
-
- K=
-
- 1.17 = Normal K for light refration, radio refration in dray,
- mountainous areas above 7500 feet elevation.
-
- 1.20 = Dry mountainous areas between 5000 and 7500 feet.
-
- 1.25 = Dry mountainous areas up to 5000 feet.
-
- 1.30 = Inland plains during winter.
-
- 1.34 = Standard atmosphere K.
-
- 1.50 = Inland Plains and northern coastal areas during
- summer; southern coastal areas during winter.
-
- 1.60 = Southern costal areas during summer.
-
- 1.75 = extreme southern coastal areas during summer.
-
-
-
- The rest of the program is self-explantory. With this
- program it is possible to plot optimum microwave and UHF
- radio paths utilizing the graphics portions of Lotus and
- Twin.
-
- For updates and registration of this software program
- please send $10.00 plus your name and address. I will send
- you a disk of other microwave programs for Lotus, Twin and
- Basic as well as a complete manual for the Path Analysis
- program.
-
- Feel free to copy this software and distribute it, but
- this documentation must be accompany all copies or uploads to
- local BBS. PATHANA.ARC must always have this PATHANA.DOC as
- part of the archived program.
