EZ-Lindenblad
by Mike Miller 12 Feb '08

12 Feb '08

I built the EZ-Lindenblad from the QST article. I have it mounted about 20 feet above the ground. The elevation radiation patten in the article is for 6 feet above the ground. From looking at similar designs at cebik.com it would appear that at 20 feet the elevation pattern breaks up badly. Is there a practical way create an artificial ground to restore the pattern to what it is a 1 wavelength above ground? Mike KC9DOA

RHCP for P3-E & Eagle?
by Peter Sils 11 Feb '08

11 Feb '08

Hello to the Group, I am considering buying a set of RHCP yagi's (2M and 70CM) and wonder if RHCP will be preferred for TX/RX for P3-E and Eagle. (Due to the cost of the switching arrangement (more than the cost of the antenna) I am forced financially to think just RHCP). Any insight would be appreciated! TNX in advance! 73 Peter KD0AA --------------------------------- Be a better friend, newshound, and know-it-all with Yahoo! Mobile. Try it now.
