Diex Antennas Two-Band Trap Shortened Rigid Rotatable Dipoles
Diex Antennas Two-Band Trap Shortened Rigid Rotatable Dipoles offer high performance multi-band HF operations, and they are an excellent choice where there's not enough space for a full-size dipole or Yagi. Crafted with precision in Brazil using quality materials, these aluminum tubing antennas are designed to withstand tough environments assuring long-lasting, exceptional performance. They are packed partially assembled, saving valuable time and effort. Typically mounted on a rotating mast, these unique multi-band HF antennas provide high-band directionality depending upon installed height above ground. Given the nature of shortened low-band antennas with limited SWR bandwidth, these antennas feature the flexibility of physical adjustment to set the lowest SWR to a specific frequency. DIEX Antennas Two-Band Trap Shortened Rigid Rotatable Dipoles power handling is 1500W PEP SSB, which is further limited if using an antenna tuner. NOTE: Diex Antennas recommends that a directional HF antenna should be mounted on a tower at a minimum height of 33 to 50 ft. (10 - 15 meters) above ground level and must be installed in the clear, away from power lines, trees, buildings or other towers and antennas.

4O3A A50 Antenna/Load Switches
4O3A A50 Antenna/Load Switches serve as 50-ohm loads for open ports on the HFC4500 combiner or other multiplexer, preventing tuning degradation. Applying 12V power connects the input to the combiner's output, linking it to the corresponding combiner or filter. A typical setup switches a filter or a combiner to a monoband antenna. When the A50 is not powered, the switch defaults to a 50-ohm termination for the input and the antenna output is open. NOTE: The A50 is NOT an A/B switch. The manufacturer's label of "A/B Switch" is a product grouping, NOT an indication of the function of this product. The LOAD resistor is internal, so one of three connectors is unnecessary, which leaves an open hole in the chassis, a "normal feature" of the A50.
