A quarter wave vertical needs quarter wave radials at 90 degrees to the
vertical.

A half wave vertical does not need radials as it is complete but needs fed
at the center with the coax running out 90 degrees to the dipole (as far as
possible)

I'm Limited To An Antenna On The Front Of My House. Out My Window I Made A
Simple !/4 wave Verticle Dipole. Would A 1/2 Wave Simply Be Twice The
Length, Using 462/f Mhz, And Would There Be An Advantage With A 1/2 Wave
Over a 1/4 Wave ?
Thanks
