LMV-2905 |
|
Applications: The LMV-2905 antenna is a fixed station, vertically polarized, log periodic monopole antenna array suitable for short range groundwave circuits and medium to long range skywave circuits in the 2.5-30 MHz frequency band. Features: The LMV-2905 is a multi-stranded array utilizing corrosion resistant materials and components requiring low maintenance. It also utilizes a smaller footprint for use where space is a consideration. Characteristics: The LMV-2905 series utilizes independent LMV-0205 series curtains arrayed in a rosette configuration distributed around a single support tower. The antenna series provides independent sector coverage. Equipment Supplied: Prefabricated alumoweld curtain, bolted 6061-T6 aluminum tower, front pole guys, anchors, copper ground screen, spare hardware, and impedance matching transformer. Optional Equipment: Galvanized welded steel tower, wood pole, obstruction lights ,ladder, climbing devices, erection kit, repair kit and repair tool kit. Coaxial cable, connector adapters and mating adapters. |
