DX Engineering XB-5 Hexx Beam HF Antenna
The DX Engineering XB-5 Hexx Beam is a lightweight directional five-band HF antenna for the 20, 17, 15, 12 and 10 Meter bands that is ideal for permanent or temporary installations. What are the benefits of this oddly shaped HF beam antenna? There are many, such as its small turning radius and full legal-limit power handling on all bands. But the most important are that the XB-5 Hexx Beam receives signals very well and transmits RF very efficiently. Its special configuration of full-size wire elements reject noise so more signals are heard. Months of development have culminated in this advanced antenna design for easier assembly, improved SWR and better bandwidth while maintaining excellent front-to-back performance. The DX Engineering XB-5 is our best Hexx Beam to date. DXE-XB-5 is the complete HF antenna package of specialized DX Engineering XB-5 Hexx Beam components; some are new and pre-assembled. These essential components include the patented* Hexx Hub and the Stainless Steel and PTFE Rigid Flat Feeder which is fully balanced with the Maxi-Core® 20 1:1 Current Balun and Mount. Also included are the all-new Heavy-Duty "Ice" Spreader Support Ropes with thimbles and stainless steel carabiners, better fiberglass Center Post and Spreaders, the Heavy-Duty Mast Mount, newly configured Element Wire Kits with the unique DX Engineering Wire Guides and innovative Element Spacer Insulators.

DX Engineering PRO-STACK Broadband Antenna Phasing Switches
DX Engineering PRO-STACK Broadband Antenna Phasing Switches are newly designed to combine two identical Yagi or log periodic beams, or three quarter-wave vertical antennas, into a phased array for enhanced operation. There is no need for coaxial delay lines with the DX Engineering PRO-STACK switches. Just connect your antennas to the phasing switch controller with equal-length 50 ohm lines. PRO-STACK switch units are available with high-quality PTFE-silver plated SO-239 (UHF female) connectors. These relay units are 1-of-3 source voltage controlled at 12-15VDC over a four conductor cable. A matching Control Console is available separately or is included in the PRO-STACK System. These phasing switches can be used for any applications that require the following four basic antenna feed selections: both antenna ports in-phase, both antenna ports out-of-phase, antenna port 1 only, and antenna port 2 only. The default is both output ports in-phase. Impedance matching automatically changes when any antenna port is disconnected. Generally, stacked Yagi antennas are separated vertically greater than 1/2-wavelength free space. Since the DX Engineering PRO-STACK Broadband Antenna Phasing Systems are broadband, they may be easily adapted to larger arrays. For example, four stacked Yagis may be combined by creating two sets of two, and then using a third DX Engineering control console to combine the first two sets. PRO-STACK switches can also be used to feed three quarter wave resonant vertical antennas for a high-gain 4-pattern array. In this arrangement, the center #2 passive element is directly grounded to a good ground radial system at all times, while the end elements #1 and #3 are then fed in various phase relationships by the PRO-STACK. Details are in the complete PRO-STACK PS-2B Instruction Manual linked here in Documentation. Features of the DX Engineering PRO-STACK Broadband Antenna Phasing Switches include these great features: * Power handling up to 5 kW * Broadband coverage on 160-10 meters * High-impact RF shielded weatherproof housing * High-RF tolerant, silver-PTFE SO-239 (UHF female) connectors * Proven DX Engineering RF relays for high performance * Safe 12 VDC relay operation, even on battery or solar power * MOV surge protection on control lines * External, removable control line connector * RoHS-compliant assembly

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.
