The filter includes a casing (1) which houses a first space followed by a first filter access comprising a rod (Be) and screwed adjuster (Le) and a second space followed by the comb teeth (B1-B3) and adjusters (V1-V3). A space leads to a second access filter (Bs,Ls) before a fourth space meets the wall. The access filters and the teeth lie in one plane while between 0 and 5 rejection filters (R1e,R2e,R2s,R1s) are placed perpendicularly in the spaces. At least one rejection resonator has a resonance frequency above the central maximum of the passband filter. If two resonators are used, they both have a frequency above the central maximum and are placed in the second and third space. |
