Well, we stopped talking here a while ago.
Doesnt mean we cant continue
Welcome to the forum!
Yes, you will get 3dB of unnecessary signal dampening when receiving a circular signal with a linear antenna. Which doenst mean “bad” by definition. Just less than with two matching antennas. Also, you give away the multipath-rejecting properties of circular polarisation, which can further degrade the image.
Might be perfectly fine though, depending on your environment.
If you dont get satisfying reception, I would certainly recommend trying a different antenna combination.
