Hello Roy, Yes, an 80m / 40m arrangement would be plausible. Although I appreciate that you will be using buried radials, if the radials were elevated, a set for each band would be required.
An alternative would be to use a form of close coupled half wave resonator on 40m. This would consist of an approximately half wave length of wire (at 40m) running parallel to and spaced from the fed 80m 1/4 wave vertical, but not connected in any way to the 80m 1/4 wave wire. I have used this concept in multiband antennas. One advantage that this coupled halfwave radiator has over the paralleled 1/4 wave vertical elements, is that its 40m vertical pattern is generally speaking more useful than the 1/4 wave's vertical pattern for DX in my experience, except on "dipole nights", with less response at the higher angles. The disadvantage is that it is not a "plug in and play" antenna. 73, Geoff GM4ESD Roy Davis <r...@verizon.net> wrote on Monday, March 16, 2009 at 6:16 PM > Hi Geoff, > > Thank you for your reply, and the tip on just using a 40 element on 30 and > the reasons why.
