Collinear Antenna Array Calculator
Array • High Gain • Omnidirectional
You mayst want to add some ferrites a the feeding point (left side in the picture), so that the antenna knows,
where it begins. For the λ/2 sections, solder the inner conductor to the shield of the next element
and vice versa.
If the construction is not wheaterproofed by putting it inside a plastic tube, some heat shrinkeable tube mayst be used to protect the soldering conections.
Use as much times (n in the picture) λ/2 sections as posible to increase gain.
