281. Re: [TowerTalk] stacks on 40 (score: 1)

Dave, Why sad? If you enjoyed using it then it served its purpose. Having the ability to switch just means you can optimize some of the time - MOST of the time the stack is the strongest and if one h

Dave's original statement was "can someone model 2 40 meter yagis stacked?" .... at the time the discussion was about stacks - then got in to the relative performance of 40 meter stacks ... my intent

I had a somewhat similar scenario happen on my (somewhat) recently installed tower. The rotary 80 dipole at the top would have a low SWR until it rained when it would go up quite high. Within general

Vytenis, Sounds like a great antenna! The formula for changing it is a simple one ... first measure the actual length as is. Then put it up and measure the point where the reactance, X, equals 0. Tha

Chuck, The reason why this will work is because you are FIRST determining what the formula is for that particular antenna in situ. So if it were say 22M tall and it resonated at 3.467 Mhz then the "f

these are only starting points! Local conditions - the antenna itself, the surroundings, the ground, etc etc will all conspire to move that value up or down slightly. KNOWING what your particular ant

One should be able to get within say 3% .... 5% tops to start with right?! Measuring the actual frequency of the actual antenna and changing it this much will work ... if done properly in one go. Ive
