Setting the height of the DA1 Antenna

Haven't managed to find anywhere I can enter the height of my Catalyst DA1 antenna when on the pole. I've searched in the Trimble Mobile Manager app and the TerraFlex app.

I've tried looking for a user manual/guide on the Trimble site (https://catalyst.trimble.com/trimblemobilemanager.htm ) but the page has a 404 error

Hi Baron

That's an old URL - the new Catalyst online help portal is linked here 

With regards to your antenna height, this is not an option in Trimble Mobile Manager (TMM) but rather something you setup in your data collection app.  Take a look at the post Trimble Catalyst Antenna Phase Centre Offset  for more detail on the APC or the setup and configuration section of the online help for more information

This is the TerraFlex settings page on my device. There is no option for setting the pole/antenna height

HI Baron

You need to select CATALYST as the location service option.

Your screengrab shows it currently set to INTERNAL i.e. your phone's Internal GNSS chip

This is why you have no antenna height option.

Take a look below:

1. Select the location service
2. Plug in the Catalyst antenna
3. Follow through the prompts to connect

This will then enable the antenna settings option

Where you can specify the antenna height (to bottom of your antenna mount)
