Yeah Rick I have heard good things about the delta loop. I don't know if I have the real estate for one, but will look into it. I have 2 portable magnetic loop antennas that work really well for thei

Reed, I had a 80M Delta loop up for quite a few years. It worked extremely well. Very quiet. It was fed in the corner with 75 ohm coax, then 50 ohm to the shack. My matching piece of 75 ohm coax was

I'm sure Gary they are the best antenna for the dollar, but not enough trees here for support. I was raised on a farm & my late father, W4PFP & elmer, had some serious wire antennas. I miss the real

Reed, a 17m vertical delta loop (no a lazy loop) is what I'm talking about, and you need only about 20 ft. of width for it. It takes up less space than a dipole. The point is at the top of the single

Use a telescoping fiberglass pole. They don't have to be very high. 25 ft. is high enough if you make the horizontal bit a little longer. That still leaves about 7 or 8' under the antenna so that peo

One point 500/MHz =1/2 wavelength I would hate for someone to think that is all the wire they need to use for a delta loop. Using the 1/4 wave 75 ohm transmission line is vital. 73 Don KO7I Sent from

Delta loops show marginal gain over a dipole (1.1db), and are much more of a pain to erect.  As far as noise no real proof that is true.  And one more thing, feeding with 1/4 wave of 72ohm is more vo

Good point, Don. I probably wasn't clear. I was only referring to how to calculate the position of the feedpoint. In fact one wavelength is actually 1005/f but for the feedpoint using 250 (for one qu

Don, Excellent report and reflects some of what I experienced. The answer is found by looking closely at the details. First, the dipole was indeed quieter (as per noise) than the vertically polarized

The delta loop is around 100 ohms. I run one on 30 meters and it works great. I use a 1/4 wave of 75 ohm cable then 50 ohm cable for an excellent match to 50 ohms. Carl Moreschi N4PY 58 Hogwood Rd Lo

When you cost out Rich's design, it is not much more than other antenna options. By the time you get some No. 14 wire, coax, a mast, guying parts, etc you have likely spent as much. The vacuum variab
