[Antennas] Info/advice sought on 2 el vert array for 40m

[Ron W7MRR]

Harvey has a point.  Verticals by in large require a lot of wire in the ground or just above it.  Unless you have a large estate and don't care how it looks, this is not usually an option for the average ham.  You generally need at least 30+ radials to make an 80% effective ground, so this just isn't so good.  A vertical dipole is just that, a vertical dipole and not a vertical.  R7, R7000 and other end fed antennas have consistantly put out signals that are 1.5 - 2 S units below similarly situated full size [read 1/4 wave] antennas, so this isn't exactly an improvement over a dipole either.

   Best bet is to consider wire antennas of gain if you have the room.  They are cheap and less time consuming to put up.

Hey Harvey,<br><br>How about a vertical dipole?  Or a OCF vertical like the R7 and later, and <br>the GAP antennas?  They work pretty well, and don't need an extensive <br>ground plane.
