Topband: Help for Preamplifier

[Rainer Kühnberger]

Hello Topbander.  
  
I would like to build a preamplifier for RX-Loops. I still am to it on the
search of suitable band filter for 160, 80 and 40m. The filters should be
built similarly the Dunestar-Filtern. Is there somebody of this me to it in
the reflector with wiring diagram and measurements can help? I would be
grateful over every help.
