For the three band range (20-10) its really trivial. Going on down to 30 and 40 is only slightly more tricky. The ARRL Antenna Book deals with this quite concisely and gives winding data for the best
I'm pretty sure that there is a lot of evidence, both empirical and theoretical, that says pattern is important when you're trying to actually aim at something or when you're concerned about interact
What exactly do you want to tell us? I canīt follow, perhaps a language problem? Peter I have asked my resident experts (U know who u r.) and added my own unschooled opinion. For the three band range
I don't know who made it, but that comment demonstrates a fundamental misunderstanding about coax feedline! When we connect coax feedline to a beam we are also (unwittingly perhaps) connecting a cond
Wilson, I tend to support your view. Back in the days, there was little or no use of baluns. Look back at my 1960s handbooks and antenna books and the mention was rare and certainly not a mainstream
My own take is that after hearing a lot of talk, much of it BS, and being exposed to a lot of colorful ads, we have developed a need that far overshadows reality. Wilson, I tend to support your view.
Not that baluns or chokes are a requirement in every situation, but "back in the days" they also thought connecting one side of the A/C to chassis was a good idea, too. At least today's Pin 1 problem
"back in the days" they also thought connecting one side of the A/C to chassis was a good idea, too. "Back in the day" it wasn't all that uncommon to get a "bite" from the microphone - another sympto
Not to mention switching power supplies. Blocking the currents that travel on the outside of your coax, from getting to your antenna and back into the coax, can save you from a lot of RFI trouble. Co
Yeah ... 'cause god forbid the misconception that we might have actually learned anything in the meantime, right? Jeesh ... Dave AB7E My own take is that after hearing a lot of talk, much of it BS, a
