Hi Ric, thanks for your time. Then I understand that it is the same reason why ground planes should be included in the antennas used in vehicles. He believed that in the ringo the inclusion of ground planes did not contribute much due to the type of polarization of the antenna. I have installed some VHF ringo antennas achieving good results in tx and rx, and keeping the ROE low (<1.5). In your experience, does the inclusion of ground planes for ringo antennas help improve the quality of rx and / or tx?
Of course, more than grateful to your comments.
Cheers,
Tommy

Thank you for your comment Ric. So I understand that when we talk that the planes help to glue the radiation lobes to the ground, is this a function of transmission, or does it also apply to reception?
Thanks again.
Cheers,
Tommy

To everything in general because the antenna is a passive element without real gain, only comparative with the reference pattern and if it improves in some sense the emission, then also the reception of a receiver connected to it. If you prefer it can be the other way around. It may be that due to the requirement of the transmitter some antenna is not suitable to emit but if to receive an example a high power transmitter connected to an antenna that does not support said power but that does not mean that if a transmitter of a suitable power is placed, the quality of reception / transmission will be according ..
