Re: [Elecraft] K3 & S9 43' Vertical

Haha, I was afraid of something like that. MD has pretty average conductivity, 4 umho/meter, compared to the 30 that is found in northeast Texas. When I was a kid I lived on Long Island, a sandbar where the value is 0.5. I had a disastrous experiment with a vertical and poor ground system the

Yup, wherever Phil was, Phil got away with it. Phil is the exception that proves the rule. Nobody near where I lived in lower New York state would get away with it (rocks for ground). I didn't get away with it in the Virginia suburbs of DC. And that was good growing dirt, too -- best garden plot

[Elecraft] K3 & S9 43' Vertical

Interesting comments on 43-foot verticals. FYI my inverted-L has a 43-foot vertical leg and 130-foot horizontal leg. 43-feet is accidental as it was the longest dimension that would fit on my eme tower and still have the horizontal wires below the 2m antennas when they are elevated. The ante

Re: [Elecraft] K3 & S9 43' Vertical

The key there being 15m and a 12 foot tank whip, which is nearly resonant and definitely not short for the frequency. The cruel reality mostly comes into play on the lower bands. Also, it sounds as if your four radials were elevated -- is that a correct read? That would make your antenna a reson

My first vertical was a 12 foot length of army tank whip (4, 3-foot sections) u-bolted to a 12 foot length of 2x2 pine, attached to the side of an enclosed patio in my backyard. The radials were four, 1/4-wave for 15 m wires at what was supposed to be 90 degrees to apart. It was fed with 50 feet of

I am in the process of installing a 43-foot vertical at my QTH (made by DX Engineering, but should be the same for purposes of this discussion). I have modeled this antenna on all bands assuming a 4:1 Unun at the base of the antenna, a 75 foot run of 9913 coax, and a home-brew L antenna at the

Re: [Elecraft] K3 & S9 43' Vertical

One important thing to note here is that Phil has avoided one of the lossy gotcha's in his matching for using 43' with 80/160 by using a large (4 inch OD) and expensive (30 smackers) #2 powdered iron toroid, Amidon's T400-A2. Don't try to short cut or cheep cut this step because you are only runni

There has been a lot written about the 43 foot antenna and the feeding of such an animal. I want to re-iterate the point that radials are so important to any vertical antennaunless it is a vertical dipole. I am using a 33 foot vertical for just 40 meters and I have 32 radials and they are

Re: [Elecraft] K3 & S9 43' Vertical

Putting the tuner at the base will be much more efficient than using the autotuner (or any tuner) at the rig end. If the tuner is at the base you will not need the unun. As someone mentioned there was a huge discussion of this type of antenna a few weeks ago. Lots of 'attitude' was displayed.

Re: [Elecraft] K3 & S9 43' Vertical

I have a 4:1 unun that I made from a balun kit (Amidon I think). It's wound just like a balun, but the connections going out are slightly different. Here's a website: http://www.iv3sbe.webfundis.net/html/UNUN.htm BTW, the unun works GREAT with an end
