Hi everyone: I'm toying with the idea of experimenting with a 4 corner horizontal loop (a project after the next project). I'm on a city lot, 50' x 100' but I think I could get a 200 to 225 foot loop

MFJ & others sell a 33 ft locking telescoping mast made of fiberglass. They collapse to 3.8 ft and weigh 3.3 lbs. It's the MFJ-1910. I have one here in my closet which I will be using for a wire ante

I have one of these, and although it works great for hoisting one end of something light or the center of a portable dipole/inverted V, I'd think they might be a bit willowy for four of them to suppo

Four many not be enough but six or eight would do it. You may also need to use some kind of rope to guy them to keep them straight since the loop would tend to tug on each pole. I would not worry too

WHY do you want to put up a LOW horizontal loop? Even on the high bands, you need to be 35 to 40 ft up for most of your energy to be radiated at angles supported by the ionosphere. On the low bands,

I agree... You would be better off with supports that radiated and a loop that did not! Chuck W5PR

For a low horizontal loop you can wind it through trees (I use #12 black plastic wire that comes in 500 feet rolls from Home Depot and less than $20). If not there is no reason why it can't be hung f

"Eliptical Radiation that is not measured by Elnec"? Sounds like "Smoke and Mirrors" to me Dave. Ground Reflection coefficients are independent of antenna type for horizontal polarization and are sol
