Hi,

As we don’t have a QK-A025+ product we can only assume your question is regarding to the A026+. The A026+ has to be powered from a 12V DC power supply. Regarding to connecting the AT011 to the A026+, you will need a braided antenna cable with a BNC male connector at one end and a SO239 male connector at the other end.

For more information, you can also download the A026+ user manual from the following link: https://www.quark-elec.com/doc/QK-A026+_manual.pdf

Hope this helps.
