Hi all-
I am ready to install my VOR antenna and am planning to build the DIY Archer antenna shown here:
http://www.vansairforce.net/articles/vorwingtipantenna/wingtip_vor_antenna.htm
(Note that a much clearer drawing can be found in the Aeroelectric Connection page 13-16)
My understanding is that VOR antennas are half wave devices. At a mid-range of 113MHz, wavelength is 2.65m, so each quarter wave leg of the antenna would be .66m or 26". The upper skin of an RV4 fiberglass wingtip is slightly longer than 52", so is there any reason why one couldn't simply lay two 26"strips of aluminum in a straight line in the upper wingtip? My understanding is probably overly simplistic, but I can't find an answer to this in either The Connection or perusing VAF threads. Knuckolls mentions that folding back the antenna Archer-style has a "marked capacity effect", but I'm not sure I understand what he means. Any thoughts would be greatly appreciated...
