Collinear Antenna Calculator. Example of collinear using eznec, we see the gain of a lossless dipole in freespace is 2.14 dbi. Recently the rason technical committee was hard at work at the repeater site repairing our 2 meter repeater antenna.
Whip for the top of the antenna. This basic calculator is designed to give the aproximate length (height) of a particular vertical antenna, for the frequency and wavelength chosen. Lütfen add blocker uygulamanızı bu site için devre dışı bırakın.
The Collinear Antenna Is Designed To Be Mounted Vertically.
We doubled antenna size, but gain increased only 1.57 db. Not open for further replies. Vertical beam downtilt can also be applied into the calculation and construction of the antenna.

The antenna space loss/isolation calculator provides a quick method to determine isolation the charts assume the antennas are mounted directly above and below each other (collinear) and the.
Mounting The Collinear ¼ Wavelength Away From The Side Of The Tower Will Give You About A 2 Db Increase In The Frontal Lobe Of The Pattern.
This calculator is designed to give the vertical length (height) of a particular antenna, for the frequency and wavelength chosen. Inches inches x 2 pieces inches inches mhz enter frequency of operation inches feed point appox. The example below checks the collinearity of three points in 2d space, and their coordinates are (1,2), (2,4), and (3,6).
