External GPS antenna

I'm interested in the DMK with external GPS antenna. We have an aluminum sailboat so we'll need to mount the antenna externally. A couple questions on the antenna:

  1. How long is the cable (and can it be extended)?
  2. Is it an external antenna, in other words, will the antenna last if it's permanently mounted externally?

    Hello Todd,

    I thought my emailed post would make it here but apparently it did not.

    Yes the cable can be extended. We ship the GPS antenna with a 3 meter chord. It has an SMA connector on it and can be extended by adding an SMA extension cable.

    The antenna is waterproof but there are more robust units out there. The GPS can use any passive antenna with an SMA connection so it can be replaced if you are uncomfortable with its durability.

    Great, thanks Kevin, I purchased the DMK 11a GPS and will be installing it in the spring and will take a look at picking up an external antenna with a rail mount!
