That's only true for 1/4 wave verticals. A 45 degree droop brings the feedpoint Z up to 50 ohms (from a nominal 35 ohms).
But, for 1/2 wave verticals (which is what this one is), the radials need to be perdendicular to the radiator for the feedpoint Z to be 50 ohms. --- On Sun, 8/17/08, wd8chl <[EMAIL PROTECTED]> wrote: From: wd8chl <[EMAIL PROTECTED]> Subject: Re: [Repeater-Builder] Re: Low Band Base Antenna Info Wanted To: [email protected] Date: Sunday, August 17, 2008, 6:45 PM Also I remember there is an optimum angle to "droop" them to get the main lobe at the horizon-I want to say between 30 and 45 degrees down from horizontal. Affects impedance too if I remember...it' s late....
