For this exercise, remove the helix antenna (clockwise polarisation) from the case and fix this using the additional cable for changing the polarisation, to the N-to-SMA adapter.
A helix antenna is a circular polarised antenna. The direction of winding of the helix, determines whether clockwise (CW) or counter-clockwise (CCW polarised waves can be transmitted or received.
Thus, rotating the antenna about its own axis has no effect on the polarisation
The X-band LNC SO4100-8A and the microstrip antenna SO4 100-8N form the test receiver. Connect both together using the N-connector. Now, insert the test receiver holder on the antenna stand, SO4100-8E. Turn the test receiver together with the microstrip antennae so that the visible dipoles of the antenna are horizontal (horizontal polarisation)
