[RFI] TVI (digital TV)

[OZ1AXG Flam]

Hi

Any idea where i can pick up a 480 MHz HIGH pass filter for TV (or build 
one)... i have tried local stores and danish internet shops wthout any luck.

Transmitting on anything from 1.8 to 434 MHz blacks out the nighbours TV. We 
have located the problem the the Digtial ReceiverBox (proberly the build in 
pre-amplifier is without any form of antenna input filtering).

In a distance of 5 meters from the antenna, using 100 mW with my VX-2 on 
145.550 MHz, i can block the reception. The signal goes to zero on the the 
receiver box.

Setup:
