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.
