Today up for bid we have an AM band deletion filter.
This filter will begin attacking the AM band at 520 Khz and increase attenuation as frequency increases.
You can see this in the screen capture of the swept filter.
I designed this filter to attenuate the AM band in when I was DX'ing the LOWFER  and NDB bands below the AM broadcast band.
I have a 610 KHZ station about 1/4 mile away that was causing lots of interference.
The filter is built into a 2" x 4" 1.25"  1/8" wall aluminum enclosure for excellent RF shielding

If you have any questions please let me know.
This filter has UHF connectors.

See my other filter auctions for this model with BNC connectors

Thank you
