Description

The optional golden ring is no longer available, but if you set your Corotor or Polarotor feedhorn to an f/D ratio for .32 the performance will be fine.

It is most important that you make sure the focal length is set correctly. Generally 95 % effectiveness is having the correct focal position. The rest is a trade-off between gain and system noise.

The golden ring was used to reduce terrestrial interference not to improve the signal gain.
