V Beam Antenna Calculator

Ham radio antennas calculator.

V beam antenna calculator.

If each end is connected to earth through a 600 ohm non inductive resistor the antenna is called a terminated vee beam. This calculator is designed to give the critical information of a particular beam antenna in this case a three element yagi for the frequency chosen. The antenna calculator above will provide appropriate wire lengths for the inverted v and the dipole for a given frequency of your choice. 73 de ve2dpe claude jollet 7 rue de la rive notre dame des prairies québec canada j6e 1m9.

Enter the desired frequency then click on calculate and the optimum values for that combination will be displayed in feet inches and fractions of inches and in meters. This is a four wavelength per leg 40 meter v beam antenna. 98 zl special for 20m 15m 10m. This gain is approximately equal to a small three element yagi antenna.

The v beam antenna is the first part of a rhombic antenna. Another ham brought to my attention that i should have indicated if this yagi antenna calculator is built with the yagi beam elements isolated from the boom or not isolated. That antenna requires a great deal more real estate than i have available but i figured if i could get something pointed to europe i d be doing just fine. Ham radio software.

The edz v beam with design freq at 51 110 mhz will work with very high forward gain at the design freq and as a normal kb4xj v beam at the 15 meter band look at the element length. The layout of the antenna and a radiation pattern of an unterminated vee beam. This is an unterminated vee beam which can be used as a. 96 loop antenna for tx for 160m.

Using open wire feed minimum 4 ft longer is ok but remember it is a part of the antenna at frequencies under 21 mhz will give an easy match from 14 mhz and up. 99 biconical antenna. Gain is 14 15 dbi or about 6 db over a dipole. 92 v beam antenna for 15m.

93 picnic vertical wire antenna. This page covers 3 element yagi antenna calculator the formula and basics of yagi antenna calculator are also explained with example the calculators for other antenna types such as parabolic horn dipole and patch are also mentioned. It omits the closing end of the rhombic. 97 morgain dipole antenna for 160m and 80m.

95 phased loop antenna. 94 laid back quad antenna for 80m. I came across a great write up by sam moore nx5z in the march 2011 qst titled a four wire steerable v beam for 10 through 40 meters.
