DIY: 6 feet (180cm) prime focus dish antenna rib parameters

[Vinay]

6 feet (180cm) prime focus dish antenna rib parameters - (Do-It-Yourself) are given below:
###The tolerance in measurements error is given in ± figures.

focal Length f = 69cm ±0.5cm
Diameter D = 180cm ±5cm
depth d = 29.35cm ±0.5cm
f/D Ratio = 0.38 ±0.02

.

x and y co-ordinates for plotting curve for antenna rib with radius 90cm ±2.5cm. Two ribs in one line will give ~180cm long curve and that can be mounted.

x=0cm y=0cm
x=5cm y=0.09cm
x=10cm y=0.36cm
x=15cm y=0.81cm
x=20cm y=1.45cm
x=25cm y=2.26cm
x=30cm y=3.26cm
x=35cm y=4.44cm
x=40cm y=5.80cm
x=45cm y=7.34cm
x=50cm y=9.06cm
x=55cm y=11cm
x=60cm y=13.04cm
x=65cm y=15.30cm
x=70cm y=17.75cm
x=75cm y=20.38cm
x=80cm y=23.19cm
x=85cm y=26.17cm
x=90cm y=29.35cm
