V Beam Antenna

This is a four wavelength per leg 40 meter v beam antenna.

V beam antenna.

As such we can model it by removing the outer half of a rhombic. This is an unterminated vee beam which can be used as a. V beam antenna design august 6 2017 by arfan leave a comment 16 satsoft reference manu hflink ale antennas selcall automatic link antennas dg7ybn antennas dipole and inverted v vee design calculator. If each end is connected to earth through a 600 ohm non inductive resistor the antenna is called a terminated vee beam.

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. Ref2 horizontal v antenna for 15 meters the horizontal v antenna for 15 meters this often leds to the question of what is a beam antenna. 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. The simplest antenna for this purpose is a rotatable dipole.

It omits the closing end of the rhombic. It is easy to construct. Beam antenna can have front to side rejection on the order of 40 to 50 db. This gain is approximately equal to a small three element yagi antenna.

The v beam antenna is the first part of a rhombic antenna. In it smallest of states the horizontal vee must be one of the least researched or understood antennas. The model 3403 is a shorter version of the antenna that covers 3 5 to 30. A rotatable dipole the simplest method of taking advantage of an antenna s directive characteristics is to rotate it.

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. Gain is 14 15 dbi or about 6 db over a dipole. The layout of the antenna and a radiation pattern of an unterminated vee beam. 1 is a 15 meter.

One can quickly see the advantage of using a beam antenna. 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.
