Re: [Elecraft] Antenna Quandary
Unbelievable answers (really). If someone asked if anyone was knowledgeable about contesting or say eme, would you just answer yes or no? Or would you offer assistance to the questioner? My first ham antenna was a folded dipole for 40m. It was described in my first ARRL Handbook as there were no nearby hams to ask and in 1958 there was no internet. TV twinlead was locally available so was easier to make than one requiring coax. I soldered a PL-259 directly the twinlead feedline and connected to my DX-35 (which loaded it FB even with high SWR that, at age 14, I was unaware of). For HF half-wave, center-fed, dipoles have been my favorite. Currently have a 80/40M inverted-V (fan-style). Wire lengths slightly longer for resonance than for horizontal dipole. Cut slightly longer than formula (492/F) and trim until SWR matched. I have ends supported with nylon cord over pulleys to lower for cutting. 73, Ed - KL7UW __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com

BTW -- there are a couple of very useful graphics that help understand this at the beginning of Chapter 8 of ON4UN's "Low Band DXing," another great antenna book published by ARRL. One shows the ground reflection as a mirror, the other, paragraph 1.3.1 in my 20 year old edition, shows how feedpoint R and X vary with height for an 80M dipole. Ground conductivity is not shown, so I'm guessing it's computed for average ground. And I agree with W4TV about the usefulness of the Antenna Book. I contribute both to it and to the Handbook. These three ARRL books have been central to my learning, in some ways, at least as important as my EE education. 73, Jim K9YC __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com

On 5/11/2022 6:51 PM, Richard wrote: Jim — I just finished building a half-wave 40-meter dipole and have it nicely tuned for the middle of the SSB segment. Out of necessity, the tuning process was carried out with the antenna horizontal. Feedpoint Z of horizontal antennas is slightly affected by height and surrounding objects, so ideally should be tune at the rigged height, then lowered and re-adjusted if necessary. *QUESTION 1:* Should I ever hang this antenna as an inverted V, would that result in a significant change to the location of the sweet spot? Slightly. When we finally got the leg lengths to the point where the SSB sweet spot was damn near perfect, we had folded back 30 inches of excess leg wire on each leg. The excess was not twisted around the legs but instead laid parallel to the leg wires and Gorilla taped in place in several places. Remember that SWR is NOT a measure of antenna performance, it only tells us approximately where it is resonant. That's because the feedpoint impedance varies a bit with height, thanks to the reflection from the ground coupling back to the antenna. Folding it back as you have done is perfectly good technique -- the antenna ends at the fold (that is, where it goes through the insulator. We routinely do that when rigging new wires. *QUESTION B:* I’d like to cut off 12 of the 30 inches of excess wire, leaving 18 inches in case I or some future owner wants to retune down to the CW segment. Will shortening the excess wire from 30 to 18 inches influence the sweet spot? SWR matters two ways. First, the match at the transmitter must be good enough that the transmitter can put full power into it. Additional loss due to SWR doesn't matter much until the SWR gets pretty high unless you're using small diameter coax or it's a long length of coax. As long as you have an antenna tuner (really an adjustable network to match the transmission line to the rig), any SWR below about 2.5:1 is plenty good enough unless the line is long enough, or small enough diameter, to have a lot of loss. That's why smart hams use big coax like RG8 or RG11 to feed dipoles. Low dipoles are closer to 50 ohms, high dipoles are closer to 75 ohms. Low would be much less than a quarter wave, high would be much more than a quarter wave. That feedpoint Z also depends on ground conductivity. SO -- since the full width of 40M is a small as a percentage of the frequency, so a half-wave dipole cut for 7150 will be just fine to cover from 7,000 - 7,300 kHz. Ditto for all the bands above 40M until you hit 10M, but even there, unless you work FM, which is at the top of the band, a dipole tuned to about 28.45 MHz will be "good enough" for where all the action is. BTW -- as study all this stuff and learn to use the tools, there is antenna modeling software that will let you learn by modeling. Here's a study I did several years ago on the effect of antenna height both as text and slides. http://k9yc.com/AntennaPlanning.pdf http://k9yc.com/VertOrHorizontal-Slides.pdf 73, Jim K9YC Looking forward to your input. Cheers. Richard That said, what's your question? OF COURSE there are LOTS of folks here who know a LOT about half wave dipoles. I have six of them in the air for different bands and directions. 73, Jim K9YC __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com

The Antenna Manual is the far better reference for questions about a half-wave dipole. 73, ...

I'd bet that every single one of those engineers who got us to the moon learned electronics and radio from The Handbook. That said, what's your question? OF COURSE there are LOTS of folks here who know a LOT about half wave dipoles. I have six of them in the air for different bands and directions. 73, Jim K9YC __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com

Re: [Elecraft] Antenna Quandary
It's showing up on the reflector. Kind of leading, no win question. But I'm a suckered. Been using 1/2 wave dipoles for 60 years. What is the question?
