I need to figure out the windload of helix antenna, specifically
a 16 turn version made by G3RUH. I have no idea how to do this.
Here are the specs....
Frequency 430-450 MHz
Rating 1 kw
Reflector 600x600 mm
Helix diameter 240 mm
Length 2.8 m
Weight 4.0 kg
The antenna uses HD40 aluminium for the boom, ultra-violet resistant
black nylon for the spacers, and the helix structure is 10mm
There is a picture of it on James' web page:
Any help is appreciated!
73 & thanks in advance
