Capacitance hat manual

 · The critical items are the half-round file and tube. Both must have dimensions that match the diameters of the crossing tubes. In my case the ID of the ¾" tube matches the ½" of the capacitance hat tube diameter. My set of half-round files -- coarse, medium and fine -- have a curvature equal to 1" diameter that is a perfect match for the 1 Estimated Reading Time: 6 mins.  · CHAMELEON ANTENNA CHA CAP-HAT Capacity Hat Kits increase the electrical diameter (and therefore the bandwidth) of your antenna. This electrical change makes the antenna more efficient. CHA CAP-HAT features: * Need to be installed between the two sections of a CHA V1, CHA V1L, CHA V2L. * For use with any sectioned antennas with 3/ . where C is a positive proportionality constant called capacitance. Physically, capacitance is a measure of the capacity of storing electric charge for a given potential difference ∆V. The SI unit of capacitance is the farad (F): 1 F ==1 farad 1 coulomb volt= 1 C V A typical capacitance is in the picofarad () to millifarad range, (). 1 pF=

Capacitance Hat CH-1B Capacitance Hat (Black) The CH-1 is designed to help in two ways. First, you can use the capacitance hat with a whip as short as 30" and get the same frequency coverage as the 6' whip without sacrificing performance. Second, you can add the 6' whip to the top of the capacitance hat and get a big improvement in performance. After Building John K6MM m Antenna, I got the idea that the Butternut HF9V may also benefit in some ways from a capacitance hat. I noticed that DX Engineering had an addon kit for another unit but I figured with some modifications I can make it work. So I did order one and using a couple of radiator clamps, conductive grease it turned out OK.

Fortunately, there is a better solution, and that is by capacitively loading the antenna by installing a cap hat! Generally speaking, the more capacitance above the loading coil, the higher the radiation resistance. However, cap hats increase the wind loading and bending moment stresses significantly more than a whip.

Capacitance for these circuits comes from what exists between the windings, the radiator and the capacitance hat. On 6 meters the vertical wire, together with the adjacent section of antenna, form a short-circuited 1/4-wavelength transmission line which cancels current flow.
