Filter hacking for 2395 ISS TV

[radiogareth]

Having been sparked into action as a result of Phil and Jens CAT25#2 talk, I raided my 'possibly useful ' filter pile and spent some time trying to tweak them for a useful passband centred on 2395MHz. Neither were suitable as-removed from service, but after a while spent screwdriver tweaking I have ended up with this passband.
-33dB at 2390, 7dB insertion loss (two filters in series) -14dB at 2400.
A G4DDK preamp should overcome the loss and the low side cut-off might just shut out the 5G.
Thoughts welcome....
No I have not found the screws to move the unwanted peaks elsewhere, but other than resonance and coupling (hidden behind 60+ torx screws) they have all had a good old tweak to see if I could....
All done with Satsagen
