Curious as to why you don't ground the shields. Grounding the shields was the only way I could get rid of some florescent lamp noise. It changed the tuner settings just a smidge. I suspect that if th

I would want to see a terrain analysis, e.g., the effect of your terrain on the idealized pattern of your 40 meter antenna. But in general, the 70 foot height suppresses high angle radiation, and has

Unfortunately, modeling the linear loaded elements is problematic at this time. Some are working behind the scenes to get some research to bear on it, but nothing useful yet that I've heard. One of t

When stacks are modeled, you can see changes in element currents of the adjacent yagis, they are not independent of one another. These changes reduce the 3db intuitive figure to something over 2db, d

Hi, I believe the confusion lies in the use of "gain" in an esoteric term, rather than to describe something which makes us louder than the other guy in a pileup. Reflection Gain is apparent gain (ma

Well, not as a really noticeable change in antenna system gain. However... A major improvement may be gained in front-to-back and front-to-side, which in the receiving mode, may be worth it's weight

However, the effects are more pronounced on the stack's ability to deeply cancel high angle reception. The effects can be easily modeled with EZNEC, which allows the phase, and feed power levels to
Once an antenna has been assembled using a PVRC mount, what you describe is fairly common. It allows the mount per se to be reused for other jobs. It also reduces the leverage the antenna has to pull
One 15/40 combination that seems to work in proximity is when the 40 is made of Force 12 folded elements (the "N" series of F12 40m beams). The folding causes the secondary resonance of the 40 N elem

The linear loading allows the 7 MHz length to be SHORTER tip-to-tip. It is an easy exercise on EZNEC (or ...) to show the movement of secondary resonances when a 7 MHz element is folded. When you mod
