[TowerTalk] CB to 10 meter antenna

[K7GCO@aol.com]

In regard to modifying the Moonraker--even if properly scaled to 10M it's 
major value is only in horizontal polarization.  Vertically polarized there 
is the unavoidable tower/mast interference which creates lift off the free 
space pattern and F/B is ruined even if the DE is somehow matched to 50 ohms. 
 It's just a 50 ohm matching device for most of the RF to the tower/mast.  
Beef up the boom and mount it all on one side of the tower.  You can get some 
independent horizontal and vertical polarization that way.  Put another beam 
on the other end of the boom pointing the other way.  K7GCO

 Hello Tom,
 Hmmmmmmmmmmm  The Moonraker I remember from CB days was a 4 element
 quad, and yes, it can be modified for 10M.

 When trouble arises and things look really bad,
 there is always one individual who perceives a
 solution and is willing to take command.
       VERY OFTEN THAT PERSON IS CRAZY!
