Is this endless sniping really necessary? Can we get back to towers and guys and antennas and propagation, please? -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Can we all ju
I am looking at two projects, both of which I may submit to QST. The first is a "low" plate voltage (45-90VDC) mini-tube QRP DSB transceiver (perhaps only a transmitter) using 3A5's and the like. Th
Why would you have a hard time? Nothing a sawzall, some self-tapping metal screws, and some silicon caulking can't handle ... ;-) Seriously, a different question, why stainless steel in a mobile ant
I need two straight sections of Rohn 45 to complete my tower project. Am located in west central Florida a little north of Tampa. I will travel a reasonable distance to pick them up. Note: The former

My Rohn manual specifies 1/4" aircraft-grade stainless steel cable and a 35' cable length. I like the ability to use both manual and electric power but want to meet, and preferably exceed, Rohn's sp
Fold-Over according to pages FO-7 to FO-10 of my Rohn Consumer Catalog. I am assembling the tower from discrete parts. One section is in a 5x5x5 foot steel reinforced 3500PSI concrete base. My plan
Just tried a buch of searches and did not find the Dutton Lainson B2503 brake winch. Is it fair to say that this is an equal or better replacement? FULTON K2550 http://www.fultonperformance.com/prod
Can anyone explain, in laymen's terms, why there is a 1,000lb difference in "MAX LINE PULL" capacity between the "1st Layer" and a "Full Drum" as well as what that means in actual use? MAX LINE PULL
Why couldn't you had been my math or science teacher in high school? You nailed it so I could understand it on the first try ... I still have trouble with algebra and geometry! Years ago someone had
That sounds very familiar! Definition of terms: http://en.wikipedia.org/wiki/Pi http://en.wikipedia.org/wiki/Radius Fascinating ... after plowing through some of that methinks I'd rather roll out th
