The Feed

A simple feed which works quite well on the 85cm offset dish if u place it in the right spot. mine is closer to the dish than the original lnb was. the length of the radiating wire is critical. for a good swr u will have to adjust that in steps of 0.5 mm.

there are enough detailed construction plans in the internet. mine has a radiator diameter of about 7.5cm, reflector diameter 12cm, 3cm distance radiator to reflector.
