Well, since this has become at least in part a referendum on YO, I'm going to toss my hat strongly into the YO ring. My experience with it has been very positive. Since you're talking about stacking

CAUTION -- second-hand information! I have a 259B, and have never personally seen or used an original 259. Having given that caveat -- a friend of mine has one, and he told me that one principle diff

Yaesu's $800 digital "solution" is a bad joke. Here's a tip: http://www.idiompress.com/rotorcard-dxa.html I know several people who have used this product, and they all love it. It is compatible with

This debate about under-the-house or around-the-house is moot in my case, as the house foundation, floor, and frame are already in place. So going under the slab is not an option. The concrete patios

To conclude this rejoinder, YO also works great under Windows 2000. I've been using it for a year that way. You can create a desktop shortcut for it in the standard fashion, and place that shortcut i

This seems counter-intuitive on the face of it. Raising a higher-frequency antenna N feet will produce a lower take-off angle (and generally better on-air results) than raising an identically designe

This is a really valid design, though, if what you want is to cover the local area pretty thoroughly on a low-frequency band like 40 or 75. No skip zone! It would be great for regional nets that cove

I want to run a "stack" of two 6el 6M yagis, one at 60 ft and one at 30 ft. Using a StackMatch to switch A/B/A+B, I can cover all radiation elevation angles between 3 degrees and 15 degrees within ab

Dan, This looks like the antenna called the "Hy-Gain 66DX" in my Yagi Optimizer 7.5. The dimensions you give are very close to, but not EXACTLY the same as, those given in the model. That said, the Y

To see how spacing affects take-off angle, install and run the YT (Yagi/Terrain) software that comes on the CD-ROM with your ARRL Antenna Book. Basically, stacking couples two or more yagis such that

Jim has articulated a very interesting approach to the question of covering the range of elevation angles for 6M. I like the idea of retaining the enlarged aperture of two yagis for the higher take-o

If you look at Mosley's website (http://www.mosley-electronics.com/faq.htm), they clearly use their split-dipole direct-feed approach as a marketing strategy -- simplicity, stability, etc. But any ra
