1001_1002_1005_web_picLP-1005– This model is the only log periodic of its kind with unprecedented transmit capability over the full 3-30 MHz bandwidth and a 2-30 MHz receive capability. Previously this could only be achieved with large rhombic or wire log antennas requiring several acres for installation. The LP-1005 offers the same rugged quality and efficiency that has made other log periodic antennas so popular.

LP-1001– This model is an established leader in the field, providing a transmit bandwidth of 4 through 30 MHz. The unique design characteristics of this antenna provide reliable high power capabilities for communications over short, medium, and long distance point to point circuits.

LP-1002– This model has been designed for high power HF/VHF coverage for commercial, industrial, and military applications. It exhibits high gain and reliability for medium to long range communications.
