The current is highest nearest the center feed point, so INHO, all else being equal you want that as high as you can get it. Worst performance would be ends up high and center down close to the groun
Buryflex works for me. Loop installed in 1997 just replaced as preventive maintenance, but it really didn't need it. Another installed in 2004 still looks great. 73 John N5CQ I am in the process of r
Do you know if the "main power line" is 7200V or 14400V? The older lines are 7200 and more prone to transformer issues. At my site, when they upgraded the lines to 14400 the line noise got much bette
Grounds are likely not uniform in the horizontal dimension either, nor in the time dimension. One would have to do very difficult and granular measurements of small cubes of soil and then build a hig
The other thing that K5IU was clear about is that the ground under the antenna is the dominant factor in performance regardless of the radials you use. If you have really low conductivity soil under
BTDT. 30 ft best compromise spacing for 20-15-10. Wider spacing may result in too many high angle lobes on 10. Will lower be fixed or rotable? 73 John N5CQ Sent from my iPhone _______________________
It can tell you how each antenna will do individually but does not calculate the combined patterns exactly. 73 John N5CQ HFTA should never be used to try to optimize stacking distance. It simply does
I was advised years ago by one of my trusted "Elmers" who had lots of experience with radio gear in the Navy that it is better to cut a window in your radio room than take a risk of an unexpected or
Jim, See the photo at https://drive.google.com/file/d/1eu8pSe_UvdPCsdKR5-trK3GlmE-G1SfV/view?usp=s haring The 15M beam just above this guy ring had major SWR issues before this insulator was installe
If the beam is more than 10' away from the guy grips, it may not matter. In my case it was just above and the SWR was very much affected. I estimate the grip plus attachments without the egg insulato
The underlying elephant in the room, borne out buy all the tables in the article, is that the conductivity of the soil is much more important than the dimensions of the radials. If you have really po
