Built-in tuning capacitor

Table 2 summarizes the built in tuning capacitor value available for LRI2K and LRI1K.

Customers using LRI2K in 21pF version can use LRI1K as a direct replacement without

needing to retune their antenna.

For customers using any other LRI2K tuning capacitor version, a redesign of the antenna

will be necessary to restore the desired tuning frequency.
