Shortened Vertical Antenna Calculator
TQWT Cabinet for JA8008 (back to top) As discussed in detail in the HES article, the price for high efficiency plus low-end extension is size. However, the choice of driver size and basic parameters for the JA8008 allows a modest cabinet size; that is if you think 80 net litres is a fair price to pay for 94-95 dB sensitivity and 40-45 Hz bass extension. Here is a formula and calculator for creating a loaded (shortened) quarter wave vertical or balanced dipole. The original javascript was created by Jack Ponton and can be seen here. As seen on his page, the original formula seems to come from an article by J. Hall, “Off-center loaded dipole antennas”, QST Sept 1974, 28-34.

Bass Reflex Box Calculator Onken Bass Reflex Calculator Calculate Speed of Sound in fibrous material Calculate the Required Amplifier Output Power Calculate Back Loaded Exponential Horn Calculate Tapered Quarter - Wave Tube Calculate Baffle Diffraction Loss. Tapered Quarter Wave Tube (TQWT) loudspeakers. The TQWT is among the best loudspeaker enclosures I know. It will let you hear music as music is meant to be heared: all the details are being passed to you at the speed of light and it will give you a up-front projection of the stage.Not every unit is good for this enclosure: units designed for the use in a horn won't do good at all. Overview: This is a calculator for designing a 1/4 Wave Flared Vent T-Line/Horn/Bass Reflex Enclosure. The formulas used in the calculator create a design that suggests the most maximally flat response in an anechoic environment based on the number of drivers, the thiele small parameters and the allotted dimensions specified in the user’s input fields.Continue reading →.
