10 GHz dual-mode feedhorn - simulation
I recently salvaged a 1m offset dish that I’m planning to use on 10 GHz and need to build a suitable feed. To determine the dish properties and parameters for a suitable feedhorn I used the Wifi calculations option in Parabola Calculator version 2.0 (same code as W1GHZ’s HDL_ANT program).
Dual-mode feedhorns are frequently used for offset dishes because of their performance. The W2IMU Horn Design and Template option in HDL_ANT generated the following dimensions for a dish with a f/D = 0.
