CRPA antenna range: eight GNSS anti-jamming models
| Model | Best for | Elements | Max jammers | Weight | Anti-spoofing |
|---|---|---|---|---|---|
| TX-S65-4CH-SNBTX-S65 | Small drones where every gram counts | 4 | 3 | ≤130 g | — |
| TX-009Pro-8CH-BD-WG-DTTX-009Pro BD | Fleets that need a second band matched to their receiver | 4 | 3 | ≤500 g | — |
| TX-009Pro-8CH-G1-WG-DTTX-009Pro G1 | Mixed fleets on GPS, BeiDou and GLONASS at once | 4 | 3 | ≤400 g | — |
| TX2501-AJS-4CH-DPATX2501 | Light platforms that also need spoofing protection | 4 | 3 | ≤520 g | ✓ |
| TX2504-3T7A21C-WG-DTTX2504 | Long flights through heavier interference | 7 | 6 | ≤1200 g | — |
| TX-8AT-FULL-KGR-34VTX-8AT | GPS and GLONASS platforms in busy airspace | 8 | 7 | ≤720 g | — |
| TX2511-16A-SNBTX2511 | Fixed sites and heavy platforms under severe jamming | 16 | 15 | ≤1250 g | — |
| TX2512-AJS-16CH-DPATX2512 | The worst interference, spoofing protection included | 16 | 15 | ≤2600 g | ✓ |
A CRPA antenna (controlled reception pattern antenna) steers nulls toward jammers so your GNSS receiver keeps its fix. infoX builds eight CRPA antennas, from 65 mm and 130 g up to 370 mm and 2600 g, with 4 to 16 elements; two of them add anti-spoofing.
How much weight can it carry
From 130 g to 2600 g. On a small multirotor this settles the question before anything else does.
How many jammers you expect
One or two sources means four elements. Organised interference means seven, eight or sixteen.
Whether you need anti-spoofing
Two models, TX2501 and TX2512, suppress counterfeit constellations alongside jamming.
Which constellations you need
BDS, GPS, GLONASS and GALILEO are not spread evenly across the range — check before you choose.
Power budget
From 6 W to 40 W continuous. Check it against your continuous budget, not your peak.
Not sure — ask
Send the platform, the weight budget and the environment. We will name one model and say why the others are wrong.
Ask for pricing and lead time
Tell us the platform, the power budget and the interference you expect. We will name the CRPA antenna that fits. We respond within one business day.
