4243-A Broadband
Shakespeare’s Model 4243 broadband antenna is an end-fed, low profile, stainless steel whip antenna especially designed for tactical vehicles. It provides a low silhouette to prevent visual detection, and to present low drag factor to exhaust gases which can destroy a larger surface antenna when firing vehicle mounted missiles. The Model 4243’s advanced design is totally passive, delivering an instantaneous bandwidth across the entire 30-88 MHz band within a VSWR of 3.5:1. NO tuning or operator adjustments are required. Uniquely designed to meet specification for frequency-agile radios, the Model 4243 antenna is also compatible with VRC-12 and PRC-77 fixed frequency transceivers. When operating with fixed frequency radios, the passive antenna does not require tuning, band switching, a motor drive, a cable harness, or a DC voltage source to the antenna. Simply connect 50 ohm coax cable between the transceiver and the antenna. The Model 4243 provides built-in protection against high voltage electrocution from accidental contact with a power line - up to 20KV RMS. A surge arrestor is built in, for EMP protection. Its Xenoy® base is finished in 383 green paint, and stainless steel components are black oxide coated. The antenna mounts using 1/2" stainless steel mounting bolts, and hardware which is provided.
