| Dec 11, 2023 at 8:14 | comment | added | Marcus Müller | To be specific: what you think you know about antennas is wrong; a large antenna is not working at all higher frequencies, that's just not how that works! This is a pretty fundamental misunderstanding, and it might be interesting from where you got it. But it really doesn't change the fact that if you buy something that was designed to be a GNSS antenna, then it was designed to work well in the GNSS bands – and to work bad on other frequencies, because you definitely don't want to pick up interferer when you're amplifiying signals at or below noise floor. So, my answer stands! | |
