SMA Connector Band-Pass Filter BPF 118-136MHz for Air band

i wanted to show off my uh collection of uh band pass filters so whenever i tear apart something and i see a filter in it or a mixer or some type of rf device i'll rip it out of there it might be out of an rf modem or a router whatever it is i'll steal it out and uh so this this is a odd kind of little uh little filter i don't really don't know the construction of these things they almost look like a little resonant cavity three of them like it resonates in each each one of these so three pole i don't know so i pulled this out of a pc board and then i've just soldered on some sma connectors so those aren't originally it was actually mounted onto a pc board and i removed it and put on the connector so we'll look at this one this one's supposed to be around 800 880 megahertz so that's that's the first filter uh the next filter is going to be this one this is comes in a metal can this one'
