Topband: Vertical dipoles in the real world

[Milt -- N5IA]

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, 40 Meters and 75 Meters SSB were 4-squares.  80 CW and 160 were 
single verticals.

If you want, reply directly to me and I will send you a few photos of the 
VDAs installed at the ocean's edge.

de Milt, N5IA

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 some suprising results, 
hope I did it correctly I am not an antenna guru . Now as Tom has just 
indicated modeling is great but its only modeling it doesnt really tell what 
happens in the real world/ground conditions etc.



Does anyone have any real world experience with these dipoles?  Do they work 
in non beach environments such as near the mountians? Comments welcome... 
and I am willing to take the comments off list if it suits you.



If this is not a fools folley I will put together what I find suprising and 
put it on my web site for everyone to access but I dont to take the time to 
document it if its a waste of time.



Jim
