- Hi, As a data point regarding de-rating crank-up towers as a function of wind speed and mast height, here's the results of the calculations I did on my U.S. Tower HDX-589 based on the professional en

- Hi All, The information that George, K5TR, has recently posted describing the antennas and their anecdotal performance at N5AU is of interest to many, and I hope others will follow his lead. However,

- I live on a 50 x 125 ft lot in Los Angeles (a half-acre lot sounds like an estate to me). Here's the current antenna setup (all on one tower): Tower: U.S. Tower HDX-589 with 18 feet of mast out of to

- I thought it might be useful to compare the claimed specs for the Bencher Skyhawk tribander with the modeled results for a similar antenna from Force-12, the C3XL. Both antennas are trapless designs.

- There's been recent speculation on the reflector about allowable tower wind loads under various conditions. As an excercise in self-education, I used the structural engineering calculations furnished
