Choosing an Antenna
We’re often asked: is it okay to use the ANN-MB2 antenna (ELT0317)? Here's a checklist of questions to help you decide if this antenna suits your needs. If the answer to all the questions (except the last one) is no, then ANN-MB2 will likely work just fine for you. If you answer yes to any of them, a different antenna may be a better choice.
Are you a professional surveyor? Do you need a top-tier antenna? Then you’ll want the Choke Ring 380 mm antenna (ELT0314). Just €2800—and it’s yours. ?
What’s the climate like where you’ll install the antenna? Do you get snow? Could water flood the antenna? Could birds perch on it? What about cats? Raccoons? Monkeys? Kangaroos? Pythons? If so, go with the Survey 160 mm antenna (ELT0123). It's not the cheapest, but its shape offers excellent protection from weather and wildlife. If the price feels a bit steep, consider the more budget-friendly Budget 38dB antenna (ELT0323). It has a shorter warranty and slightly lower performance, but it still provides protection from the elements and curious animals.
Do you need high accuracy—specifically a low phase center offset? Do you have a long antenna cable and require high gain? Then the best choice for you is the MultiPatch 100 mm antenna (ELT0194).
Are there buildings or trees nearby that could reflect GNSS signals and cause multipath interference? Then you’ll need an antenna that effectively suppresses multipath, ideally one designed with HELIX technology. Your choice here is the Quad Helix Antenna (ELT0316).
Looking for the most affordable option? That’s the ANN-MB2 antenna (ELT0317).
