The Catalyst DA1 antenna is used to provide high quality GNSS data to your phone or tablet. The antenna simply attaches to your Android device via USB cable, which is also used to deliver power to or from the antenna. The antenna is designed to simply be push-fitted to a 1.25" diameter pole, and also come with a removable ⅝" thread adapter for using the antenna with standard mapping and surveying accessories. The DA1 antenna ships with the following standard items.

If your Android device uses the new USB Type C form factor, you will need a third-party USB microB to USB type C converter to use Catalyst. To fully support Catalyst, your USB converter cable supports the USB OTG standard. Trimble recommends the Huawei AP52.
Other Trimble accessories as listed below can also be purchased individually as spares, replacements, or as optional extras to meet the needs of your application.
There are a huge range of styles and sizes of smartphone and tablets that you can use with Trimble Catalyst. Contact your device vendor for mounting and carrying options that are compatible with your device. For range pole mounting, Trimble recommends the modular X-grip series of rugged device mounts available from RAM Mount. Contact your nearest Trimble Distributor for their recommendations and suggestions available in your region.
Depending on your application and Trimble Catalyst subscription, you will have different needs for how you mount or carry your phone, tablet, and Catalyst antenna. There are many options on how to do this from third party suppliers, including RAM Mount, SECO surveying equipment, and online vendors such as Amazon. Contact your nearest Trimble Distributor for their recommendations and suggestions available in your region.
Trimble Catalyst can run on compatible Android phones and tablets but due to the processing requirements may not work on older model devices. We have provided some guidelines below to help you understand if your device will meet the minimum hardware specifications.
Trimble Catalyst connects to the DA1 antenna through the USB port on your phone or tablet. In order to power the antenna from your device's battery, your device needs to support "USB-OTG". If your device does not support USB-OTG, you can still connect and use Trimble Catalyst by powering the DA1 with the external battery pack supplied with your antenna.
Android devices with a USB Type-C connector require a USB-C adapter to operate with Trimble Catalyst. Trimble recommends the Huawei AP52 Micro USB to USB Type-C Adapter (PN AP52-W-BK).
To check if your device is compatible, download the Trimble Mobile Manager app from the Google Play store. The Trimble Mobile Manager app will check your device's performance capabilities against Trimble Catalyst requirements.
