This is true, always has been. Typically a commercial yagi is designed for single use, far and away the most common use. Stacking three plus elements does produce the kinds of improvements proffered
I would take photographs, put them up on the internet somewhere, and give us the link. You may get a precise ID if you do. Really hard to get some things across with words. :>) 73, Guy ______________

Pete, Try this with EZNEC, using the figures I gave you, and using the mininec ground, run the ground quality toward poor and watch the gain go up. Use a ground constant of .001/3 and you should get
Finally dug up the specifics of the disparity. To say that Mininec is "inaccurate under .2 wavelength" because ground loss inaccuracies can become "significant" really doesn't do the job about when t
Oohh. Not without using graph paper to draw and reentering the coordinates. Would love it if someone had a better way. --. .-.. 73, Guy Guy Olinger, K2AV k2av@contesting.com Apex, NC, USA -- FAQ on W
This seems to be one of those degree of effect things. Model ling of plain (no traps, no bends, no loading, no 4 inch element separations, just aluminum tubing, etc) elements and their combinations h

Folks, Attempting to figure my way into a properly modeled Force 12 stack. Have several good EZNEC models of the C3, etc. But have nothing from anywhere on the EF240S, etc, which are linear loaded. T
Hi Gedas, If you pick any of the fixed width fonts, that diagram should display correctly. If you are committing to a k9yc block, then just read his graph and put that in the load at the top of wire
Hi Dave, Question A) From your description, I need to know the height above ground. Question B) Exactly what did you mean by tuned radials? Do you mean radials carefully adjusted to 1/4 wave, or smal
This thread is for Dave. So I'd rather not hijack this thread for a separate and likely lengthy topic. So I will not comment here. Please start a separate thread with a separate subject that includes
Well, the best way to understand it is to scale it to 40 meters. The height is important because it's effect is set by the height in wavelength, rather than absolute height. On 40 meters the scale eq
That's really short for use at top band. Take the tap to the highest point that doesn't rotate, bring the wire down out 4 or 5 feet from the tower, and use an omega match. 73, Guy http://join.msn.com
You may have hit the nail on the head. Sounds exactly like an expensive antenna to erect in those circumstances. If you can get your mitts on telephone poles cheep and have a means to erect... Even g
It is a formidable task for an experienced modeler. Full of difficulties. It's like trying to learn how to hit a baseball starting on major league curve balls. directors and a an http://messenger.msn
Modeling a TH7 will be difficult in any event, due to the need for exact component specifications in the traps. It would be better to use an existing model for a non trapped beam of the same number o
I remember sometime being told to use a one foot diameter conductor for a tower, but that was a while ago, and there are some older email caches that got lost in a HD crash. That's difficult to use i
