The Dp-312 is a transportable, wideband HF antenna designed for short range skywave circuits. The horizontal polarization permits operation over all types of soil conditions without the need for a ground screen. The antenna operates over the 2 to 30 Mhz band with some performance degradation, however a tuning unit or coupler is not needed over the 2 to 30 Mhz band.
The DP-312 utilizes a 50 foot telescoping mast to enhance transportability and provides ease of erection and disassembly. Air dampened retraction is used to ensure smooth, safe operation of the telescoping mast. The antenna is lightweight, rugged and can be erected by two men in 30 minutes.
The DP-312 has a gain of -11 dBi at 2 Mhz, the gain increases to -5 dBi at 8 Mhz and above. The VSWR is 2.0:1 or less over the 2 to 20 Mhz band and 3.0:1 from 20 to 30 Mhz. At the lower frequencies, the maximum radiation is toward the zenith and the azimuth patterns are essentially omnidirectional. The antenna is designed for 1 kW average, 2 kW PEP.
