The Dipole antenna set AD-100 is a standard antenna designed for operation over the frequency range of 30 MHz to 1 GHz. These dipoles were designed per ANSI C63.4 requirements.
The antenna set consists of four baluns, two pairs of fixed length elements and three pairs of adjustable extension elements. The fixed length elements were designed to minimize drooping, especially at low frequencies where the tuned dipole is quite long. The dipole antenna can be tuned to any frequency in the specified range by adjusting length of elements on each side of the antenna balun to the half wavelength of that frequency (measured from center notch of the balun.) These lengths can be achieved by attaching together pairs of fixed and adjustable elements (lower frequencies) or a pair of adjustable elements (higher frequencies) to each side of the antenna balun. All baluns have BNC connectors of signal input and output. The antenna can be mounted on a tripod such as model AT-100 or model AM-400 antenna mast.
- Low Balun Loss - Less than 0.5 dB
- Adjustable Elements - Allows frequency tuning
- Fixed Length Elements - Minimize drooping
