The source sheet gave insertion loss and ripple without a symbol. This revision states them as maximum values (≤).

Return loss is calculated from VSWR ≤ 1.3: RL = −20 log10((VSWR−1)/(VSWR+1)) ≈ 17.7 dB.

The table wrote 1802–1833 MHz. The file name is 1802–1883 MHz, and on this set the file name is the passband. The 8 was typed as 3. This sheet uses 1802–1883 MHz, bandwidth 81 MHz.
