Now that the glacier has receded from Wisconsin, I want to put in radials around my 80' AN Wireless tower (free standing no guy wires). About 20' out on an arc of about 75 degrees I have an old stone
I would stake them down at base of wall, go up and over the wall, stake them down on other side and continue out. Stan, K5GO _______________________________________________ __________________________
An experienced local MW broadcast engineer and low band ham, VE6LO now SK, did some experiments with radials on a 160m vertical he had with a yard that also had obstacles. Using a RF current meter (s
With that info I might be inclined to use the same amount of wire and put down 5 times as many 20 foot radials in that 75 degree span. Obviously there would be some amount of bend which would have no
Hi Don, Interesting observation, no doubt accurate given the qualifications of VE6LO, but I wonder to what extent this reconciles with assertions by K9YC, and, I think, N6LF, about radials serving to

Radials on/in the ground aren't resonant. Most of the current in them will be close to the tower regardless of the length of those radials so put down as many as you can at whatever length they come
Sent from my iPhone Yes, however the engineering on radials has progressed past asking whether onor in-ground radials are resonant and now considers the benefits of reducing resisitivity of the soil,
Sent from my iPhone least .4 wave long. Thats a min of four tenths of a wavelength. At .4 wave long, the distance between the far ends of any 2 adjacent radials is optimized. In ON4UNs low band book,
Has anyone suggested to just tunnel under the wall? I don't know the construction of that particular wall, but stone fences in Kentucky are just dry stone stacked. A sharp stick would poke a hole und

I concur with Dave if the stone wall is close to the feedpoint -- go through or just under the wall with the radials. It avoids the wire zigging over the wall, and the possible current issues therein

When you have a structure in the radial field that you can't go under or remove, the standard broadcast practice is to strap around it. Let's say you have a small square shed on a concrete foundatio
Here in Scotland we're surrounded by mile upon mile of dry-stone walls, so I know the problem! Although no two walls are the same, my first choice would be to probe the gaps between the large stones
On my QRZ page https://www.qrz.com/db/N7WS when referring to adding more radials under my Inverted-L I mention using care since every bit of vegetation on my property has thorns or burrs as can be se
