Hello, something with experience in Vee Beams? I friend told me about this antenna and I did a search in internet and seems that with 2 or more wavelenghts you have a considerable gain.! How about fo

forget Eznec and get an old Radio Amateur handbook from the 60's to eighty's and you can find all you need to know about Long wire, VEE Beams and Rhombic antennas It will tell you the gain and tilt a

The problem with Rhombics and Vee beams on 160 meters is the same problem that all horizontally polarized antennas have. With horizontal polarization you need much more height above ground to get re

Jorge, I had a Vee beam in Arizona for many years. It is a great antenna. Mine was 120 meters long (each leg) and 20 meters up on a 20 degree mountain slope, about 100 meters above the valley. It wor

-- Forwarded message -- Thanks to all for the information. I forgot to tell that the idea is a SLOPING Vee Beam, apex at 110'' and the 2 ends at ground level, terminated in a 450 ohms resistors conne

For a sloping terminated vee starting at 110 ft and sloping to ground, I don't think it will beat a 160 meter vertical no matter how long you make the legs. That is just too low to the ground. If you

Jorge, The apex would have to be much higher then 11o' for the antenna to be effective on 160 meters. With 160 meter long legs (about the minimum that still works) the apex would have to be at 100 m

Jorge, I tried a similar approach in the late 70's and early 80's with a 300 foot tower support but the interaction of the feedline, the tower, made any significant improvement uncertain. The use of

Take a look at http://www.antenna.it/military/vr%2023-f.htm This is a military version of a sloping terminated vee. Although it is rated for 2-30 MHz, it won't have much gain on 160m. If you double t

Even at that height, this discussion has not taken into account the polarisation coupling effects that have to be considered at MF. In some parts of the world you won't get good coupling into the ion
