Hi. Looking at this product but do not see a link to a cable that would be used. The [description](https://www.sparkfun.com/gnss-multi-band-l1-l2-l5-helical-antenna-locking-sma.html) includes a warning stating that a locking SMA connector is required. I plan to connect to this [piHat](https://www.sparkfun.com/sparkfun-gnss-flex-phat-lg580p.html).

Welcome @kbares! Sorry for the confusion - any SMA cable is compatible with that antenna. Here is our [10m SMA cable](https://www.sparkfun.com/interface-cable-sma-female-to-sma-male-10m-rg58.html), [1m SMA cable](https://www.sparkfun.com/interface-cable-sma-male-to-sma-female-cable-1m-rg174.html), and [25cm SMA cable](https://www.sparkfun.com/interface-cable-sma-male-to-sma-female-25cm-rg174.html).

‘Locking’ means only that the antenna has additional screw holes in it so you, if you want, you can prevent people from simply rotating off the antenna from the SMA connection by putting in additional screws.

Yeah the “Connector-Type Notice: Please be aware that this GNSS Antenna is equipped with a locking SMA connector! It cannot be simply unscrewed like a normal SMA-type.” in the bold alert box does seem super unhelpful. Implies some kind of locking nut, or thread machining, that only allows for tightening.
