high quality antenna kabel dc-filter?

<a href="http://www.epanorama.net/circuits/antenna_isolator.html">Isolation between antenna network and TV/radio equipment</a> shows how to make both transformer and cap isolators, but no mention of loss.

Mondial designs makes the <a href="http://www.klipsch.com/mondial/index2.asp?path=/products/mondial/index.asp?frame=y&id=&line=&1">Magic Box</a> and <a href="http://www.klipsch.com/mondial/index2.asp?path=/products/mondial/index.asp?frame=y&id=&line=&1">Magic Splitter</a> still no mention of loss.

You may need an antenna amplifier or a higher gain antenna to overcome the loss of the DC filter

Hello William and James,

this problem caught me too, in the past.

Solved: my "ground-breaker" are two coupling capacitors of 1 nF soldered into the antenna plug, one for the shield and one for the hot wire. The mean thing is: yanevano which lead to dc-interrupt: shiled or hot wire. So i have both decoupled :cool:.

I used silver mica caps, no problem with sonic deterioation, no problems with loss. I have very tricky UHF receiving condition here (i want to get Austria 1 classic radio and the roof antenna is not adjusted for it; i get it as well with as without the coupling caps).
