I noticed that some of the DXpeditions are using vertical diipoles next to the sea on at least some of the higher bands ( I am guessing 20 and up). I stuffed the data into EZNEC 5.0 and came up with
There are significant differences between "verticals on the beach" and verticals (including vertical dipoles) over real ground. Google for "pseudo Brewster Angle" and see the differences between the
Jim, VP6DX 4 years ago used VDAs (vertical dipole arrays) on all bands, 20 Meters and higher frequencies. They were vertical wire dipoles with a reflector. The results speak for themselves. 30 Meters
I once heard an old wives tale ..................I think............... "verticals on the beach, horizontals high on the hill" me laddie, cackle cackle, or whatever old wives say....... mike w7dra __
Not on Topband, but I rigged a vertical dipole for 40M in one of my tall redwoods with the top insulator up about 100 ft. It worked, but not very well, not nearly as well as the horizontal dipoles at

Hi Jim, Back some 30 years ago, or so, we had just moved to a brand new house that was blessed with a back yard full of tall, majestic poplar dollars--and I was blessed with a perpetually empty bank
Jim, I put up a short vertical dipole for 40M. It is 25' tall and has top and bottom X-shaped capacitive hats that are 42.5" square with a perimeter wire attached. The lower capacitive hat is about 6
In the early 60's I had a full size 40M vertical on top of a 70' pine tree with a bunch ....maybe 8-10...of radials tossed over the branches and weighted with lead fishing sinkers. It was a superb DX
Jim, yes considerable! A ringo ranger is a vertical half wave using "end feed" and they work great. I prefer end feeding, using hte method of the ringo (which is easy to scale to other bands). I purc
Yes we do, just remember the signal George AA7JV from Mellish reef, Willis or Chesterfield. BUT the antenna near the water in the beach does not work so well, the antenna must be in the water as you

Jim, I'm very interested in your experience with vertical vs horiz dipoles for 40 meters. I have a similar situation in the works. I am using a vertical dipole for 40 meters with the top attached to
Tom, All you say is correct and anecdotal evidence is spotty at best and I understand this. But sometimes some of the guys, being big DXers have insights that I and many others dont have. Having wo
http://www.qrpdx.com/ant.html I think these are a great idea for simple, inexpensive directivity. I'd like to throw in the idea of trying this with a Moxon beam. As a horizontal antenna, there is no

Well Tom, all I can say is that it works...... Here is more data.... The mast was a wood pole about 12 feet long and the feedline was buried, so there wouldn't be much radiation from them. There coul
Tom, in addition to what I said in my first reply, there is one thing that did surprise me. As I mentioned, the mast is wood (not metal), so I would expect current to be flowing in the feedline. Whic
Here is some fresh data on my Vertical Dipole versus my Double Zepp. This was run last night and is typical of the reams of comparison data that I've accumulated on 40M. My methodology: I find a clea
