LPH-0308/TA |
|
Applications:
The LPH-0308/TA is a transportable, horizontally polarized log periodic antenna designed for HF skywave propagation circuits for short and medium paths. The antenna is designed for directional broadband transmitting and receiving in the 4 to 30 Mhz band. Features: The curtain is made of vinyl coated galvanized aircraft cable. The coating provides corrosion protection and improves the handling of the elements. The transportable tower is made of panels which interconnect with quarter turn fasteners to form triangular sections. Captivated quick release pins are used to connect the sections to form the tower. Characteristics: The antenna provides an instantaneous bandwidth of 4 to 30 Mhz. The azimuthal -3 dB beam width is typically 80 degrees. The elevation patterns are set to accommodate short to medium skywave paths. The gain varies from a minimum of 8.5 dBi at 4 Mhz to 11 dBi at 30 Mhz. Equipment Supplied: The antenna comes equipped with a prefabricated curtain, transportable aluminum tower, guys, front poles, anchors, balun and transit cases. |
