Intuitively, without actually modeling the array you converted to, the heavy radiation is near the dipole feedpoint. In the sideways V configuration the horizontal placement of the radiation was "fuz
Has to be a real one. If you want it to be powerful it has to be the only card you have from a rare country only manned once in the last twenty years that you haven't shown ARRL yet. And it will be d
Pulls water INSIDE the elements by wicking. Maybe if you worked clear automotive silicone *grease* into the outer yard or so of rope that would solve the wicking. I've always wondered what some of t
There is something that happens to rookie cops a lot. Every driver is a closet speeder, if you can catch them. Everyone sitting in a parked car at night is up to no good, etc, etc... It has to do wit
In GENERAL, of course, I have NO argument with your statement of PRINCIPLE, nor have I posted such. But "shadowing" as used by various posters in this thread is an obsolete term that does not intuiti
I'm at work, so don't have my diagrams to look at, but I seem to recall that the 40N series DE has an inductor at the center for impedance matching, so it really ISN'T a split dipole. The conundrum y
I'm going to use a prop pitch to do that. (C31 & 340N). -- Guy Olinger, K2AV Apex, NC, USA I will run the C-31. primarily for sloping is pretty yagi from about 22' of I have rotor, have gain than tho
To all of you going nuts trying to figure out [or defend your perception of] the difference between a quad and a yagi... The most important set of dB's is in the mind of the contester. I remember a s

Not going in circles for me. Proof? It's not like this is an unvalidated/unmodeled antenna from a fly-by-night company, though we unfortunately do have some manufacturers of that ilk. For general pur
Absolutely. Just remember not to rivet the pieces. Don't bother with the goop. Push one rivet from each set of holes through the innermost hole, and wrap black tape around the element to hold the riv
I note that you are testing across 50 ohms. A lot of receivers are nowhere near 50 ohms resistive input. Did you test these levels across 250 or 1000 ohm termination? Or with no termination except th
There are other benefits besides pattern deterioration: Without the balun, something like 1/3 of our power can head back down the feedline shield as longitudinal current into our shack. This is usual

Hi, Tom, et al, Precisely. And that is my observation as well. It is this exact thing that convinces me that the real mechanism for the snow static is still not really nailed down. If the phenomenon
A 60 foot boom you say? If you can put it up with a crane or a helicopter. And if you have a prop pitch to rotate it. Even then, have you ever seen a tower wind up underneath an antenna before it sta
To: <towertalk@contesting.com> No, not ALWAYS. Definitely CAN be huge. In the case of the F12 x40N series of antennas, the linear loading produces an antenna that is not resonant at 15 meters, as op
The example you quote, C19 and 340N, is probably an exception that proves the rule. In general I agree with W8JI's assessment. These two antennas, though, carry time spent in *developing* an independ
You realize, of course, that you can buy those two antennas on the same boom, the C39XRN. The 40m driven element is between the 10 m reflector and the 15 meter reflector. 40m reflector is way out bac
Read the description carefully. On the C39, the 40 DE is BETWEEN the 15 DE and the 15 reflector, NOT behind the 15 reflector. They HAVE had to deal with removing the 21 mhz resonance from the 40 "N"
