I'd say it depends on two things:
- Whether you have other applications for the wider bandwidth of the 1R5
- Cost
The 1150LN used at BM offers slightly higher gain and slightly lower
noise for only $25 more; it's probably worth the extra money if you have
no use for the wider bandwidth of the 1R5 (10-1500 MHz is a *lot* of
spectrum!).

Cheers!
