This Broad band antenna offers excellent performance. This is a “blade” style antenna with an adjustable right angle elbow. Overall length is 7.75” (20 cm) in a straight position, and 6.75 “ (17.2 cm) in a right angle position. Peak gain on all bands is 3 dBi. The halfwave design means the antenna is ground-plane independent; the antenna can be used on plastic or metal without concern for proper ground size. The radome material is a semi-flex polyurethane, providing some give when stressed but maintaining long term durability.
