V Beam Antenna

2 the versatile vee beam our second fiweekend antennafl project is an aerial that you can use on all eight high frequency amateur bands 80 40 30 20 17 15 12 and 10m with an antenna tuner and which gives significant gain on the five bands from 20m to 10m.

V beam antenna.

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. The ten tec model 3402 broadband terminated vee beam antenna offers continuous coverage between 1 8 and 30 mhz with a maximum vswr of 2 1 typically 1 4 1 or less. As such we can model it by removing the outer half of a rhombic. 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.

This is a four wavelength per leg 40 meter v 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. Gain is 14 15 dbi or about 6 db over a dipole. Beam antenna can have front to side rejection on the order of 40 to 50 db.
