Booty Monster I love that Antenna to death. But Rule Of Thumb says you are not suppose to make wraps like that with your coax being the feedline transmission. it will eliminate noise yessssss . but you will loose velocity as well as gain factor and forward gain . this has been proving when some of the big boys do that on there beams and they make silly wraps like that . you get a weak spot or a hot spot in time when you run power through it , and in time the coax will fail at the wraps cause the energy will be so compressed and focused like running current through a small piece of 16 gauge wire. your performance would be much superior with an AIR VARIABLE CAPACITOR with a voltage rating of 5000 volts or higher . 3-200 pica farads is nice . sometimes you have to go lower, it will depend on your wavelength.
