-> WS> Any ideas for a new series on antennas?
->
-> How about a TV antenna conversion to 2m or 70cm ?
-> Not one of the `average' type tV antennas most people have but one of
-> those
-> large `fringe range' antenna monsters.
-> Largest one I have seen in RS catalogue is over 6 feet long and
-> would be a nice base to start from for a 70cm beam.
-> Or maybe use it for a VHF/UHF LPDA base of `parts' to start with?
-> Slice the boom down the middle length-wise and then work on the
-> elements and
-> spacing a bit to cover 144,220,440,900MHz .
  That has ben done for hte Scanner Fans. Bill Cheek in one of his books
has outlined the conversion of a Standard TV antenna for Vertical
polorization and use on the Public service bands. But rembember the
antennas are designed fro 75 ohm cable or 300 ohm twinlead. Matching
would present another problem fro transmitting.
-> What about the antennas that look like a parabolic dish for TV
-> channels 14 and
-> upward ? I see this type a lot in the upstate New York area on
-> several houses.
-> Wonder if it can be used as a platform for a  1.2GHz or 10GHz
-> project ?
  I am sure it has already been done. But you have the same 75 ohm
designed feed line impedence to deal with.
