I know you said BPF. A lot of us use the BLP-200+ LPF from Mini Circuits on the 2m side to help with desense

Mini-Circuits makes some SMT filters. The downside is that they're SMT
with small solder pads.  The other thing is, they are power limited to
0.5W.

You can buy them individually from Mouser or Digikey, and I'm pretty
sure you can order *free* samples of them from Mini-Circuits.

You can buy breakout PCBs for them from ebay, for example (the boards
use SMA connectors):

The downside is that they're SMT with small solder pads.  The other
thing is, they are power limited to 0.5W.  They offer other types of
bandpass filter, but I haven't done an exhaustive search...
I've used them for the receive end, they work as advertised.
