Stan, I don't think that anyone has mentioned the additional wind loading of the 105 foot mast. 105 feet times 4"/12" pipe diameter times about 0.6 to convert to equivalent flat plate amounts to an a
Roger, T in Base-T indicates twisted pair 2 in Base-2 refers to a maximum of 200 meter long segments using thin coax 5 in Base-5 refers to a maximum of 500 meter long segments using thick coax Now, i
Ed, First, you are correct that even if you didn't try to use the two antennas in a stack, you would definitely see a benefit in having two antennas at different heights in respective of vertical tak
"The FHJ cable was discontinued over 20 years ago. It is said to have been replaced due to its poor long-term attenuation stability. The attenuation per foot increases over time." http://lists.conte
Bob, The 46 foot figure refers to a second bracket at that height (46 feet). The tower requires two brackets. So, the line you are reading is for a 60 foot tower which is bracketed at 23 feet and 46
Thanks for all of the responses to my "dilemma" that I am having to endure in moving to the East Coast. I have an additional question. (Won't be the last time I say that.) I would like to put up a C3
Rather than suggestions that the idea be dropped, I am hoping that someone actually does have some useful thoughts on how to do this. This is also a topic that is on my to do list. I have an existing
Clay, If you stick a 25G on a pier pin, you can pretty much ignore what typical tower movement might be. The tree is going to be holding up the tower. I sort of liked the suggestion to put up a ladde
Has anyone measured corroded copper inductor Q vs. shiny new copper at HF frequencies? Specifically, I wonder if there'd be any practical benefit to polishing and coating a 3/4" copper pipe transmitt
I am curious about how antenna manufacturers and antenna mechanical design programs determine the maximum windload ratings for an antenna, in particular yagis. It occurs to me that for a typical yagi
you You could both be right on the figures that you are seeing / expecting. According to 4nec-2, a 40 meter dipole at 78 feet up shows about 12 db FS for a take off angle of 25 degrees, where it has
