DX Engineering PS-3B PRO-STACK Three Antenna Phasing Unit - $470 - (Mogadore, OH)
PS-3B PRO-STACK Three Antenna Phasing Unit DX Engineering PS-3B PRO-STACK Three Antenna Phasing Units offer the ultimate performance for combining three identical Yagi or Log Periodic directional antennas and may be used for vertical antennas in a phased array. Pro-Stack frequency independent broadband phasing devices operate with three mono-band antennas on any band, from 160 through 10 meters, for pattern and null steering that wins contests and snags the rarest DX! Signals arrive at your antenna system from different azimuth directions and different elevation angles. Adding a stacking phasing system to a rotational array adds the ability to steer the pattern of the antenna array in two planes, azimuth and elevation, and to move the major lobe and nulls. The greatest advantage of Pro-Stack arrays is the ability to move harmful pattern nulls away from signal arrival angles. While gain makes a marginal improvement, moving a 20 to 40 dB null can be a phenomenal change, so the Pro-Stack can make the difference between a barely readable and a strong signal, providing the performance edge needed to work rare DX - and win contests. DXE-PS-3B Pro-Stack Phasing Units are 50 ohm relay systems that handle up to 5 kW. A separate user-supplied automated controller or the optional DX Engineering DXE-EC-PS3 Control Console for these 12-position rotary switch selections: - Three antenna ports in phase, default with no power to control console. - Antenna port 1 only - Antenna port 2 only - Antenna port 3 only - Port 2 out of phase, Port 3 in phase - Port 1 out of phase, Port 3 in phase - Port 1 out of phase, Port 2 in phase - Ports 2 and 3 in phase - Ports 1 and 3 in phase - Ports 1 and 2 in phase - Ports 1 and 2 in phase, Port 3 out of phase - Ports 1 and 3 in phase, Port 2 out of phase - Port 1 out of phase, Ports 2 and 3 in phase These PRO-STACK units may also be used for other applications requiring these feedline selections. To ensure lowest SWR, impedance matching automat…
