Hello and thanks for reading this,
Question! (Practical answer Required)
" Half Wave End Fed " antenna, In a copy of QST Feb 2007
there is a reveiw of a 20 Mtr 1/2 wave End-Fed Dipole, (Par Electronics)
searching through my many antenna books,
I find Nothing on matching the High Z of a 1/2 wave to 50 Ohms!
CB/10Mtrs have had end fed 1/2 wave Ant's for years, and
I have seen 1/2 waves for 2Mtrs,
The picture in QST just shows a Small moulded block with a SO239
on the side and a terminal for the 33Ft wire,
and it Does NOT need a network of ground radials.
This would be handy for /P Ops, But at $43.95 I am not about to
buy one to cut up and find out What is in it !
Anyone wanting to have a look, their Web site is
www.parelectronics.com
Any Info greatly appreciated,
Gordon, G4TZX @ GB7COS
