I know that the TV transmitters have adjustable low pass filters that should do just fine. . I will see what reject & BPFs they have. The frequencies you mention are right in our land mobile range (USA FCC allocation).
There are several other uses of that area for frequencies that may be tunable for your reject filter in the USA. Check this chart (Long) https://transition.fcc.gov/oet/spectrum/table/fcctable.pdf
Now, when there is a commercial transmitter farm (A few to hundreds of transmitters per site) ALL must have specific traps & filters, so as to not create intermod distortion, harmonics & specifically stop many frequencied that are more important than a TV transmitter. These need to be tunable, to adapt to each site.
I’ll see what is in my pile of stuff here. Maybe you can find similar where you are.
