Thanks, Zoli. Maybe the balls are metric. If you have ability to know for sure I would like the information. Stan _______________________________________________ _____________________________________
Keith, Since you took it apart, if you think you can put it back together I would recommend you clean it up and, provided you believe replacement of the bearings will make it work as it should, put i
How far away (minimum) should a receive antenna be located if you wanted to accurately measure the difference between a couple of vertical arrays - lets say, for example a 4 Square and a single verti
Im missing something. How do I get 180 out of 2 * 900/80? Thanks, Jim. Stan Sent from my iPhone _______________________________________________ _______________________________________________ TowerTa
Im thinking that since 22.5 meters on 80m, for example, would put the RX antenna on top of radials from the closest vertical and it would be way too close. I would not be surprised if you measured fi
Eric, I think at minimum I would replace whatever you are using for a balun with something new and up to date from an engineering standpoint. There arent any 20 year old balun designs, whether a coil
Anyone out there proficient with YagiStress who could give me a little help. I want to check some numbers before cutting tubing to make some 40m verticals and unfortunately don't have the software wi
Big thanks to Billy, AA4NU, for putting my numbers in Yagi Stress and sending a screenshot. He has always been helpful to others on this reflector. In case it helps anyone, the numbers I gave him tot
Paul, An alternative which works great for me is to start a quarter wavelength of wire out a few feet, insulated from and up about 50 feet on your 160m shunt fed tower. Run it down at an angle so at
I just ordered ten boards. I will not be back to USA until March 24. They should be there when I arrive. I will probably use 4 or 5 of them and if anyone wants one and is not in a hurry, they will be

I have been using these on this trip. https://www.ebay.com/itm/184465408028 They have a rubbery boot on the end for further protection from water. I use a dull utility knife to strip an eyeballed ~ 5
I am interested in knowing what the detriment might be if you had a 80 foot tower with a large Yagi for top loading within four feet of a 20 foot tall concrete building with lots of rebar and a metal
It will be guyed but, of course, with non conductive guying. _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contestin
I would be quite pleased if it only attenuated signals a small amount and only in the direction of the house. That would be from West to South going CCW. Currently my tower is 30 feet SW of house and
Huh? So 55 feet for spacing and segment length and about 17 feet for the diameter of the wire for 160m.??? My house isnt big enough for two wires in a model. Sent from my iPhone _____________________
I recently needed a two conductor cable for 12vdc power to an obstruction light. Wasnt happy with the flimsy stuff I had and instead used RG-6. Pretty cheap and rugged. Stan, K5GO/ZF9CW _____________
I am interested in talking directly via email or phone with anyone who has had a professional engineer provide specifications or drawings for a guyed tower installed in sandy soil. Although my plan i
A couple years ago I reduced power from 1200w to 50 watts to thin a gigantic pileup of Europeans on 160. Rate went way up after about five minutes. I think even without that situation occurring you w
Larry, I would suggest you consider an antenna that would look like a capital I or an H turned 90 degrees. Feed it in the center of the vertical part and make the top and bottom horizontal portions t
