Weather balloon??


In my dreams (smile).


There is a JA station with a full size 80 meter 4 element beam 1/2 wl in height on a tower with a rotor, heard he lost it in a typhoon though.


ON4UN has a full 1/4 wave vertical for 160 meters.


 thought process is, 1/4 wl vert. loading coil for another 1/4 wl now have 4/8 add another 1/8 in top hat cap loading should give a 5/8 wl vert.


 The radials will be 1/8 wl with coils making it another 1/8 wl or a 1/4 wave.


  Probaly be to lossy with the coils to show any efficiency, oh well I sure enjoy the 75 meter DX, just cant think of any way to improve the performance of that 1/4 wl vert due to size  of antenna.
