But would not the gain of these antenna's compensate for that, from say a 3 DB to 6 DB gain verticle to a 13 DB foward gain, directed in each direction. > 2) Aperture gain is less using this method, versus 10' worth of vertical > stick. > > Ken > > At 01:27 AM 5/25/2004 -0000, you wrote: > >I have a crazy thought, but I want to get some opinions.
