<p>Create beverage page</p> <p><b>New page</b></p><div>The &#039;&#039;&#039;Beverage&#039;&#039;&#039; is a travelling-wave antenna: a very long, very low wire, classically used for low-band reception. It is highly directional along the wire.<br /> <br /> == Geometry in SimTX ==<br /> A single straight wire along the azimuth, mounted very low; the model caps the height at 3 m regardless of the height setting, which reflects how Beverages are built. Default length 80 m; a length of 0 selects two wavelengths at the operating frequency, and real Beverages are typically one to several wavelengths long.<br /> <br /> == Characteristics ==<br /> * Typical gain figure around 8 dBi of directivity along the wire with a very low takeoff angle around 8 degrees.<br /> * As a travelling-wave antenna it is inherently mismatched and lossy as a transmitting antenna: expect a permanently mediocre SWR (around 2.8) and note the high default feedline loss (2 dB). Real stations use Beverages for receive, not transmit.<br /> * Very directive front lobe toward the azimuth heading; point it at the target region.<br /> * Works best over average to poor ground.<br /> <br /> == When to use ==<br /> Mostly for experimentation and for simulating receive-style directivity on the low bands. As a transmit antenna it is deliberately inefficient; a [[Vertical Antenna]] radiates far better on the same bands.<br /> <br /> [[Category:Antennas]]</div>
