Overview

DX Engineering PS-3B PRO-STACK Three Antenna Phasing System

Dominate the airwaves with a DX Engineering PS-3B PRO-STACK Three Antenna Phasing System. Achieve ultimate array control and performance with three identical Yagi or Log Periodic directional antennas or use the system for vertical antennas in a phased array. DXE-PS-3B Pro-Stack Units are frequency independent broadband phasing devices that operate with three antennas on any bands, from 160 through 10 meters. Select from twelve combinations of in-phase and out-of-phase for pattern and null steering that wins contests and snags the rarest DX!

DXE-PS-3B-P PRO-STACK Three Antenna Phasing Systems consist of one DXE-PS-3B Relay Unit and one DXE-EC-PS3 Control Console with manual 12-position rotary switch. This advanced system requires only 9-conductor control cable and standard 50-ohm feedlines of equal lengths to each antenna.

DXE-PS-3B Pro-Stack Broadband Three Antenna Phasing Systems offer these compelling features:
- Power Handling up to 5 kW
- Broad band coverage on 160-10 meters
- RF Shielded Weatherproof Housing - unique protection
- DXE-PS-3B has High-RF tolerant, silver - PTFE SO-239 (UHF female) connectors
- DXE-PS-3BN-P are high-quality silver-PTFE Type N female connectors
- DXE-PS-3BDIN has Amphenol Connex 7-16 DIN Panel Connectors
- Proven high current DX Engineering RF Relays
- Safe 12 volt DC relay operation
- MOV surge protection on control lines
- RoHS compliant assembly

DXE-PS-3B Broadband Phasing Units provide the greatest flexibility for three identical antennas. This relay unit contains a broad-bandwidth high-power 2:1 impedance matching transformer. This eliminates common requirements of using mixtures of 75 ohm and 50 ohm phasing or delay cables for impedance matching. Feedlines to each antenna from the relay unit must be the same cable of the same length and match the antenna impedance. So all of them need only be as long as the longest, to reach from the antennas to the relay unit. While it is best to have feedlines of equal electrical lengths, there is no need to closely phase-match cables; cutting the antenna feedlines made from the same coax to equal physical lengths is sufficient.

To ensure lowest SWR, impedance matching automatically changes when any antenna is disabled. By switching between antennas at different heights above ground and/or changing the phase relationship between multiple antennas. The old standard system in stacks was to activate or disable specific antennas in the stack to change pattern. However, with the Pro-Stack system, gain remains higher when all antennas are driven and phase is changed, plus this system allows phase inversion as well as the ability to switch any single antenna out of the array.

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. This is accomplished by switching between three identical antennas that are properly spaced for phasing, as well as changing the phase relationship between the antennas to effect changes in the null positons of their elevation patterns.

The greatest advantage of equipping your array with a DX Engineering Pro-Stack is the ability to move debilitating pattern nulls away from signal arrival angles. While gain makes a marginal improvement, moving a 20 to 40 dB null can make a phenomenal change in reception. So, the Pro-Stack can make the difference between a barely readable and a strong signal, thus providing the performance edge needed to work rare DX - and win contests.
