I had an interesting discussion with a friend over the weekend and wanted to get some input from the TowerTalk community. Imagine a 1/4 wavelength wire hanging down from a tree with the bottom end at
I had a vertical for 160 on a small peninsula in salt water. I ran the radials into salt water in 4 directions and pushed aluminum tubing pieces into the bottom in the salt water with the end of the
I think there are 2 different things in the same picture: - antenna next to the salt water gets its radiation lobe closer to the ground (the salt water). that's because the pattern is determined by c

For those who enjoy modeling you might want to take a look at this "vertical on a beach" thread which was posted on eHam several months ago: http://www.eham.net/ehamforum/smf/index.php/topic,98217.0.
Verticals have always held a fascination for me. But I wonder to what degree my fascination is overly influenced by misleading articles and unscrupulous advertising. There is a ham...maybe about 3 mi
There is a place called SOUTH ALKALI FLAT between Steins and Gary New Mexico that floods during rain storms. New Mexico I-10 exit 11 Good place to test antennas and no power lines. I had a gap vert.
This talk on vertical antennas... interesting .... but one thing I have learned over many antenna party installs..... no two are the same... and Vertical antennas, have that be ground mounted, Raised
It helps if you actually take the time to study and learn how verticals work. There are two tutorials on my website that address exactly that. One focuses on 160M, the other asks (and answers) the qu

The EZNEC help has a very good summary of this. In the Help > Index look for "Vertical Antennas And Buried Radials". If you don't have EZNEC installed (any version, even the Demo) the help is availab
JIm, Thanks for the clarification, it's very helpful. Alternative modeling results will be very interesting. Grant KZ1W EZNEC doesn't agree with your conclusion about azimuthal pattern. I modeled a 1
