Garmin GA 25 BNC GPS Antenna for Colibri, LX20, LX5000, LX7000 and LX7007 Products
Includes a 2.9 m (9.5 ft) cable with a BNC connector.  A similar antenna is included with the Colibri, LX7000 and LX7007.  It is not compatible with the LX8000.

Removable Magnets Installed
The antenna has 2 magnets installed under a thin metal plate on the bottom of the unit.  The magnets can be removed using a small screwdriver.  Just remove the clear plastic sticker that covers the back and set it aside.  Then remove the 4 screws at the outside corners.  It is not necessary to remove the 2 screws near the cable.  Then remove the metal plate and remove the 2 long flat magnets.  Then re-install the metal plate, 4 screws and clear plastic sticker.

I can shorten the cable to any length you desire.  I charge $19.95 for the new BNC connector and labor.  You can select the cable length when you place your order. There is also an option for a BNC-RA BNC elbow adapter for $9.95 (see below).  With the BNC elbow adapter the minimum recommended antenna cable length for mounting the antenna on top of a Colibri is 8 inches (20.3 cm).  Without the optional elbow adapter 10 inches (25.4 cm) is the minimum recommended antenna cable length for use with Colibri.
