Seminole County, FL was 100 MPH based on the old "fastest mile" standard. Without finding a new chart that uses "peak gust", 139 MPH would seem to be equivalent. Requiring the calculations or a PE ce

I'm curious to know if the fence would act similar to good conductivity dirt WRT Beverage performance. Anecdotal reports over the years (~ 30?) of Beverage antennas over an existing conductive wire/f

I too have had Mosley antennas over the years (TA33 and TA36) and in both cases I noticed a significant improvement in performance when I replaced the TA33 with a Cushcraft A4 and the TA36 with a HyG

In terms of raw gain the Yagi will beat the 4SQ hands down. However, much of that gain will be at too high an angle to do much good outside 1500 km. 73, ... Joe, W4TV Wish someone have some analysis
