ANTENNA:
JUNO-LPA requires the addition of at least on antenna for radio operation. JUNO-LPA achieved
FCC “Modular Approval” for use in Digital Electronic Devices in combination with the noted
antennae. Use of antennae other than these listed can required recertification of the module in
the end-product. (See “Agency Certification” in this document for brief information). The
JUNO-LPA WirelessUSB™ Radio Module User Manual contains complete regulatory
compliance information.
Customers may obtain antennae (part numbers UGADL1B1M1 or UGADA0B1M1) with the
following properties:
