The first pic is a 1/4 wave nmo mount antenna and if its about 12" then its cut for about the 220mhz ham band. The other two are either 800mhz cellular or 800 or 900mhz LMR antennas. Would need make/model numbers or sweep them with an analyzer to know exactly what they are for.
fineshot hit it on the head On the first one the mount will probably cost as much as the antenna or more, so hopefully you have it all. Seems to me that ive seen the second one advertised somewhere as a scanner antenna.
i have mounts and coax for all the antennas. the second and third antennas dont have anysort of marking to identify make/model. both were on magnetic bases.
