B&W AC-1.8-30

The Barker & Williamson AC-1.8-30 [AC110] End-Fed Vee is another unique antenna from B & W! Utilizing the same technology as their folded dipoles, it can offer operation over the entire HF band without need for an antenna tuner. This antenna features grounded operation, excellent for lower to ground and metal roof top installations. Work any frequency you want without going through a lot of knob twirling and measurements to get a good SWR match - just set your frequency and go! Hop frequencies at any speed as long as you want, as there are no mechanical parts or active components to wear out. It is great choice for ALE radios. It is not limited to conventional ham bands. It is great choice for ALE radios. Tune any frequency in the antenna's bandwidth, and have VSWR of 2:1 or better. Capture weak signals in receive mode. Much better performance than any vertical.

This unique antenna design covers a continuous frequency range of 1.8 to 30 MHz, with a VSWR of less than 2:1 across the entire range when fed with a 50 ohm coaxial cable. The 110 foot (34 m) antenna is terminated at both ends by ground stakes (not included). The center of the antenna must be supported approximately 25 foot (7.6 m) above the ground. A counterpoise wire (supplied) may be necessary to join the two ground locations, especially in roof top or other applications where uncertain ground conditions exist. The antenna is omnidirectional at the lower frequencies, with mostly high angle radiation useful for long distance. From approximately 5 to 15 MHz, the radiation at lower angles increases, and above 15 MHz the antenna becomes more directional in the line of the antenna wire, toward the balancing network. In applications where space is limited, the wire may be shortened without greatly affecting the VSWR, but lowering the radiation efficiency. Power rating is 1KW (2KW PEP).
