Abstract
The present invention relates to a radar level gauge () comprising an antenna (), a tank sealing (), an electronics unit () and a waveguide feed () between the electronics unit () and the antenna (). The waveguide () is essentially straight and has a 90°-symmetric cross section and is further arranged to accommodate two essentially orthogonal waveguide modes. The waveguide () further has a length (I) below two times the range resolution of said radar level gauge (). The present invention further relates to a method for improved radar level gauging using a radar level gauge () as above.
