Callboost CFL915-S20

Much tighter than the Acasom eliminating almost all LTE interference, but at the cost of slightly higher insertion and reflected power loss.

Sourced from eBay.

Acasom LL915Mhz Cavity Filter

Fantastic insertion and return loss characteristics, but the pass band allows LTE to bleed in a bit.
