Zajímavý ozařovač s kruhovou polarizací na 70cm zkouší Willi LX1DB. (Díky za info Zdeňku / OK1DFC)

Hi.

Good evening and many thanks for the test this morning. In attached you find a picture of the CP feed, who consist in 4 dipoles connected by a hybrid cube.
I do have it still in and will check the results with it during activities.
The question: is the –3db to linear pol. a big loss or is in the average better like the system I do had before.
Switched Hpol. or Vpol. who is certainly not all the time in line with faraday or other  rotation due to …..

73 TNX again and nice weekend
