Notes:
1) The SPR 700 MHz and 900 MHz models have larger dimensions than the
standard SPR models. Their dimensions are the same as that for the BSR.
2) The SPR 3.5 GHz and SPR 2.4 GHz models are available in large and
standard (smaller) dimensions (chassis). The dimensions (i.e., large or small)
affect the antenna gain.
3) The 700 MHz internal antenna covers only 710 - 716 MHz and 740 - 746
MHz (i.e. Band C). To cover the entire band of 698 – 746 MHz, an external
antenna is used (see Section 2.5.2tbd”).
