		I recently erected a simple two-wire Beverage antenna and, during a recent on-the-air meeting, was asked to write it up for the Scuttlebut.
		The antenna is fed at the SW end through two transformers to match to a single 50 ohm cable approximately 60 feet long.
		Second, the Beverage direction is selected by applying 12 VDC to the 50 coax feed line which powers the relay in the matching box.

	Beverage antenna - Wikipedia, the free encyclopedia
		The Beverage antenna exploits a means of turning an otherwise largely bidirectional antenna into a unidirectional antenna by terminating the antenna with an impedance conjugate to the surge impedance of the antenna (most usually approximated by a non-inductive resistance).
		The antenna relies upon the "wave tilt" phenomenon whereby a vertically polarised radio frequency electromagnetic wave travelling parallel to the surface of the earth with finite ground conductivity sustains a loss which is reflected as an electric field component parallel to the surface.
		A single wire single element antenna is typically a single straight copper wire, of between one-half and one wavelength, running parallel to the earth's surface away from the receiver in the direction of the desired transmitter.

	Beverage Antenna Page II
		The surge impedance of the wave antenna is determined by its height above the ground, and by soil conditions with regard to moisture, etc. By erecting the conductors at a minimum of ten feet above the ground, the surge impedance remains more nearly constant during all seasons than when erected at a lower height.
		The system of changing directivity of the antennas and remote erasure adjustments as outlined is somewhat inconvenient because of required travel, terrain condition, time consumption and the fact that the antenna when made directive in one direction is not available for service in the opposite direction.
		The transmission line may be checked for signal pickup or unbalance by disconnecting the two antenna wires and connecting a resistance across the transformer in place of the antenna and equal to the surge impedance of the two antenna conductors.

	Beverage Antenna Construction
		Beverages that picked-up corona (or "p-static") noise were always near or aimed at tall towers.
		The largest noise problems came from antennas mounted high on towers, and generally were with antennas that had "sharp" ends jutting out in the air.
		Antennas located away from the towers remained free of precipitation static, whether bare or insulated.

	Terminated Shortwave Antenna -- antenna special on hard-core-dx.com
		The antenna can be viewed as a lossy transmission line, lossy in the sense that signals will not be contained between the wires, but will radiate (or signals be received) to a certain extent.
		Since the main use of the antenna is to try and improve reception over a simple whip or random wire, its dimensions are not specified, and neither is the attempt to match it exactly as a transmission line since its length is too short.
		If the antenna is installed in the attic, then in order to prevent the coax shield from becoming part of the antenna, wind about 10 turns of the coax into a loop of about 6 inches diameter (about 15 cm).

	Antenna Experiments (old, long): repost from rec.radio.shortwave
		Antenna #2 was about 8 meters of wire suspended almost vertically from a tree overhanging the cottage, connected directly to the R8's high impedance input #2.
		The ground for this antenna was provided by the grounded shield of antenna #1's coax: this arrangement is not good at rejecting noise from the power line, but with very clean power and few noise generating appliances it was usually acceptable (especially as I could always switch to #1).
		Antenna #1 was intended to be a nonterminated (bidirectional) Beverage, while #2 was intended to be omnidirectional.

	Beverage Antenna
		Beverage Antennas are considered by many to be the ultimate receiving antenna for low band reception.
		Beverage antennas are a minimum of 1 wavelength long.
		The antenna is terminated with a 470 ohms resistor connected to a 1.5 meter alu-rod drawn into the soil.

	Beverage switching box
		The first solution was to split each antenna in 3 directions with coaxial T's and to use a coax switch on each station, so that each station could select a different antenna.
		That proved to be not very satisfying, the impedance seen by the receivers and antennas were changing a lot depending on the position of the different switches.
		Beverage 1 of 160m board is connected to Beverage 1 of 80m board and to Beverage 1 on 40m board, same for all inputs.

	More Beverage Notes
		According to H. Beverage statement, I am one of part-time users of Beverage antennas which resulted in a simple fact that I built such antenna at any place I visited for temporary operation (mostly contest).
		The performance of a Beverage can be seriously affected by the energy reradiated from nearby vertical antennas.
		There are many attempts to arrange a "low" Beverage at the height of your knees or as "snake" lying on the ground.

	DX Engineering RBS-1 Reversible Beverage Antenna Product Reviews
		The antenna between the two units is standard 450 Ohm ladder line (not included) which I purchased from one of the internet wire supply stores.
		My first impression of the antenna was very disappointing, until I discovered the RG6 cable I used to connect to the feed point had a corroded PL259/F adapter which was installed last winter and properly sealed.
		The forward gain of the antenna seems to be comparible to my existing beverage to Europe which is approximately the same direction and my Africa antenna which is about 900 feet long.

	Ham Radio Beverage
		Ham radio operators interested in low band receiving antennas are certainly familar with Dr. H.H. Beverage's antenna.
		Beverage antennas are typically "receive only" - although some hams have been known to transmit with them.
		A classic Beverage antenna requires a lot of space - a long wire, one or more wavelengths long, mounted near to the ground and oriented in the direction of the desired reception.

		One thing you may have read about beverages, is that if they are to work well, they must be about 6 feet up in the air and be terminated with resistors and ground rods.
		You will be surprised by the diversity of signals each beverage antenna can hear on a frequency (due to their directional abilities).
		One important thing to remember is that a beverage which is not terminated will be able to hear signals from the west, if the beverage is run in a western direction, but will also pick up stations from the back of the beverage, the east.

	N1EU's Beverage Transformer Notes (Site not responding. Last check: 2007-10-21)
		Why Beverages need good transformers The requirements for a Beverage transformer are less onerous than for a pennant or flag, because the antenna already operates in the unbalanced mode.
		This is despite baluns (ununs) at both ends of the feedline, several clip-on ferrite suppressers, a separate ground stake and thick ground lead at the antenna, and the shack equipment all shielded and bonded to earth.
		If the antenna is also used for transmitting, tuned link coupling at the antenna should be seriously considered, due to the limited power handling capability of available ferrite cores (remember we are talking about normal transformers, not transmission line types).

		Think of the wire as serving two functions, as an antenna with the wires tied in parallel and as a transmission line to reach the far end.
		The two wire beverage has two modes, first the antennas mode (same as a single wire beverage, both wires have front and back signals present), and secondly, the transmission line mode (the two wires in the ladder line carry the far end signal to the near end).
		With an antenna analyzer like the AEA or MFJ, sweep the frequency from 1.8 to as high as 10 MHz and look for the SWR to change the least over this entire range, not just inside the amateur bands.

		Generally, the beverage had a 1-4 dB higher signal level on the middle and higher parts of the MW band, while on the lower part the difference was around 6-10 dB or roughly 1 S-unit.
		This is without doubt THE antenna for those who want to do serious MW DXing and do not have the space to erect multiple long beverage antennas.
		The beverage has the edge with regards to stations in the bearing of the beverage, but the loop plays at equal terms with stations located 30-40° away from the beverage's front lobe.

	K3KY's Short Beverage
		I had written off the possibility of having Beverage antennas for the low bands, however, because the longest side of the yard is only 216 feet long.
		I read some emails on the lowband reflector about using long wires laid on the ground as unterminated (bidirectional) Beverages, and remembered reading an interview in which Harold Beverage said that his first antenna was just a very long wire on the ground.
		I was surprised to learn it could often pull weak signals out of the noise on 80 and 160 too, though the output signal levels are not as great as those from a longer wire, and it is not as directive as on 40 and 30 meters.

		A 580' beverage works very well on 80 but is not long enough to work particularly well on 160.
		As W1WCR points out, in his "Beverage Antenna Handbook", certain lengths produce a very desirable "cone of silence" off the back of the antenna.
		Short beverage antennas have a very broad main lobe, poorer response to low angle signals & lower sensitivity.

		Secondly the antenna should be directive; thirdly the antenna should reduce the usual substantial noise level on the lower frequencies and should finally fit in a normal garden.
		Due to the fact that my EWE antennas first of all are bound for DXing on the tropical bands I determined the amount of the terminating resistor - half empirically, half theoretically and intuitively - on 820 Ohms.

		A Beverage antenna (for its inventor, H.H. Beverage) consists of one wire, or two parallel wires, mounted 10 to 15 feet above ground, and with an optimum length of 1800 feet.
		A two-wire antenna with one far end grounded, and the center-tap of the transformer terminated, will provide reception in the reverse direction (from the receiver end).
		Once the maximum signal level is reached, remove the pot, measure the value with an ohmmeter, and substitute a fixed resistor of that value.) The receiver end has a transformer (construction details in the booklet), the center tap of which is grounded through a similar resistor, or through the series phasing network previously mentioned.
