On page 98 it says "The HUM-900-PRC-UFL and the HUM-900-PRC-CAS must use one of the antennas in Figure 108 in order for the certification to be valid. "
On Page 100 it has “Specialty Styles Linx offers a wide variety of specialized antenna styles (Figure 108). Many of these styles utilize helical elements to reduce the overall antenna size while maintaining reasonable performance. A helical antenna’s bandwidth is often quite narrow and the antenna can detune in proximity to other objects, so care must be exercised in layout and placement.”
I am going to test it with different type specialty styles to get the distance needed.
I just need the footprint Thanks for the help
