Hello.... I'm going to pick brains once again. I am familiar with the antenna models for these antennas. Does anyone have actual comparisons of a Delta Loop and 1/2 wave Dipole on 40 and 20 meters? A
John, I have had terrific luck with loops over dipoles. Although there is some gain involved with the loop, depending on orientation, the big difference is noise and the loop wins big-time. They are

You also have to mention that you need to feed it 1/4 wave down from the apex for vertical polarization. Feeding it at the apex or in the middle of the base leg makes it horizontal, bad for low angle
Do you think one could put a decent loop on a suburban lot that is only 100 feet by 60 feet? How big a loop and how high do you suppose it might have to be? I figure I could put something up that is
My lot is slightly smaller than yours is. I have a full sized 80 meter loop, 85 feet on a side. It is fed at the top with open wire 'real' 600 ohm line into the tuner in the shack. It is fed at the t
For gain vs. height stuff, I'd rely more on the models, honestly. The models really tell you what you need to know. Why? Because the differences in ground clutter, soil conditions, noise sources, av
A 80 meter full wave delta loop tilted at 45 degrees fed at the bottom corner works exceedingly well for early morning dx when compared to an inverted vee at the same height. Bob W7KD _______________
Actually, the delta loop is fed at one of the lowers by many because of convenience. When fed at that location, it is more of a oblique radiation polarization pattern rather than the preferred vertic
I use a delta loop on 40m feed at one of the corners with a 75ohm matching stub. I'm sure it's not optimal but the thing works! Compared to a resonant dipole the delta loops wins hands down in my boo
Thanks for the uptake. Maybe I will try one. The guys in my Friday ham lunch bunch were also thinking a loop would work as I cannot get a straight wire out long enough. Thanks . -- K8JHR -- == == ___
Novice Alert: Could someone please identify which section of my ARRL Antenna book covers this "Delta Loop" - as that term does not appear in the Index. I do not mind doing the homework on stuff, but
No -- the delta loop is an equilateral triangle loop, called "delta" for the Greek capital letter Delta which is an equilateral triangle. The "skywire" loop (taken from the "Loop Skywire" QST article
Refer to "Quad Loops" or "Full Wave Loops" and you may find the delta configuration described and/or illustrated. Roger, N0VR Novice Alert: Could someone please identify which section of my ARRL Ante
Check out this link: http://ka1fsb.home.att.net/loopcalc.html To partially answer your question, the "Delta" loop is just a basic description of the "shape" of a full wave loop antenna. A full wavele
I'm curious why you would ask such a question. 1. Maybe you are trying to determine if NEC models predict real world experimental data. If so, you aren't going to get that from an "I built one and it
Me too. Is it that the original poster doesn't believe in science and the laws of physics? NEC works! It is an accurate predictor of how antennas work. This stuff ain't magic, and science isn't decid
Dan, thanks to you and the rest of the guys for the input. The modeling shows that a Delta Loop, properly fed for vertical polarization, has less side nulls than a dipole (at a good reasonable height
