I install SS cap screws from the bottom with a SS lock washer and nut installed for retention. Then the radials with crimped lugs are installed on these "studs" with a second washer and nut. All su
Seems to me that if the threads on the rod are fully engaged with the threads on the coupler then you have maximum strength. Additional threads screwed into air add nothing. The visual would be dis
Here in the desert southwest pack rats (White throated wood rats) are our nemesis. They are extraordinarily destructive to automobiles parked outside. I have two outside and we keep the hoods parti
https://fairradio.com/product/23cx6/ I'd be willing to do a Arduino thing that can read one and generate USB serial/RS232 output or a display. I think I gave away my box of motors to some ambitious s

I have too few (~20) insulated, 55 foot long on-the-ground radials under my 55' high inverted-L. In my desert conditions, running radials is quite literally a pain, but I will add more as time permi
No. We used them at Hughes for years until the worries about the fumes/smoke outlawed them. Wes N7WS Thanks 73 Jim W7RY _______________________________________________ _____________________________

A recent post about a new toy led to some discussion about readily available antenna analyzers that meet the special needs of Topband aficionados who have to cope with big BC band signals affecting t
Rick, With all due respect, I'm not terribly surprised with your comments, considering that you worked for HP. When I worked for Hughes, I remember several occasions where I took an airplane ride fro
Thanks. Just a couple of clarifications. The original Touchstone software was by EEsof. I had a copy at Hughes in the early 1980s. It was of course a DOS program and came with a parallel port dong
I've used a 1) Boonton 250 RX meter and 2) an HP sweep generator, Vector Voltmeter and bridge at various times at the base of my vertical antennas. I can remember a waveguide slotted line too. We l
Since you must have some grounding conductors connected to the tower for lightning protection, "insulated" from the roof isn't insulated from ground. You don't say what band(s) you might be interest
Personally, I don't understand all of the fuss about HFTA. In the general case (sans 200' towers), aren't you pretty much stuck with your environment with little to do about it? But regarding the be
Isn't that pretty much what I inferred? You put it up as high as your location and checkbook can stand and wait for the propagation gods to smile on you. Wes N7WS On 1/20/2019 11:46 AM, Jim Brown w
I'm a firm believer modeling. I use EZNEC and AutoEZ and trust them. Wes Wes? N7WS Actually Wes, this is 100% wrong if you have complex terrain. I have that here and I modeled 10, 15, 20, 40 using H
Hmm. I must remember that having my tongue firmly planted in my cheek doesn't come across in text form too often. That said, I do not work contests unless it's to pick up a band-slot from time-to-ti
