Technical description BOG

The Beverage is a very broadband long-wire antenna, which is set up close to the ground / lying on the ground (BOG, "Beverage On Ground") and does not require any adjustment (e.g. by means of a tuner). It provides a much lower output signal than a comparable, elevated, classic beverage antenna. With the BOG, however, the main focus is on a better SNR ratio. The signal can be boosted with a good RX preamplifier. The antenna should be longer than 1 wavelength and installed at a height of less than 0.05 wavelengths above the ground. The antenna is usually terminated with a resistor at the end (opposite the feed point). 

This antenna is a receive-only antenna. Feeding can be done via 50 Ohm, as well as via 75 Ohm coaxial cable. The desired impedance can be easily selected by means of a jumper in the "feeder box". This box also contains a 4:1 impedance transformer (or 9:1 for the "classic" version we also offer) to compensate for ground losses and a protection against overvoltage to protect the receiver.

The impedance of the BOG is lower than that of the classic Beverage. This is due to the ground losses. It is about 200 to 300 ohms. In the "Terminator Box", it is possible to choose between 3 terminators (230, 290 and 320 ohms).

The components meet the requirements of IP-56 and are therefore protected against water and snow.

Application description BOG

Beverage antennas are one of the cheapest and most reliable ways to improve DX capabilities on the low frequencies. Because the BOG variant is mounted close to the ground, no bulky and expensive masts or other high mounting points are needed. Thus, this antenna is ideally suited for fielddays, for example. To achieve high efficiency, the antenna wire should follow a straight line.

The connection from the receiver to the "Beverage-Box" (= feeder) is made by a coaxial cable. The antenna wire is fixed between the feeder and the "terminator box" by means of screw terminals. Finally, the "Terminator-Box" is grounded. All inputs and outputs are clearly and legibly labeled, which further facilitates the setup.

It is strongly recommended to install a common mode choke in the feed line with a ground stake at a distance of about 10 m from the antenna feed point. The antenna wire to be used must have a sheath.
