Can you make an 8 turn version in RHCP (no dish)?

I just wanted to verify... my antenna theory is a bit lacking.

Does feeding a dish invert the polarization by 180?

Also, thanks for this! Gonna try it out!

Hi, a Dish will invert the polarization. So LHCP will be RHCP.

Also please add a make when you printed one :)

I just finished the 7-turn version and tested it with a 60cm offset dish.
Wow, that thing rocks!

Thank you!!

Thanks for your comment. Great to hear that it works so well for you.

Please add a make/made with an image of the Feed, that would be awesome.


Just say if you want another, more detailed picture.
