ANTENNA CONNECTIONS
JK1 – If an external antenna extension kit is required to improve cellular performance, connect
the antenna extension cable to JK1. This deactivates the on-board antenna and allows the
product to use the external antenna. (See Figure 1.)
JK2 – The secondary receive antenna, mounted on the right side of the product enclosure, is
attached to the communicator using JK2. (See Figure 1.).
