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

DX Engineering PS-3B PRO-STACK Three Antenna Phasing Units
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 that cover any band, from 160 through 10 meters. Pro-Stack frequency independent broadband phasing devices operate optimally with three properly spaced mono-band antennas, but can be used with three identical stacked multi-band beam antennas, 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 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. 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. DXE-PS-3B Pro-Stack Broadband Three Antenna Phasing Units feature: - 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 UHF connectors - DXE-PS-3BDIN has Amphenol Connex 7/16 DIN Panel Connectors - DXE-PS-3BN-P are made with high-quality silver-PTFE Type N female connectors - Proven high current DX Engineering RF Relays - Safe 12 volt dc relay operation - MOV surge protection on control lines - RoHS compliant assembly Get a DX Engineering PS-3B PRO-STACK Three Antenna Phasing System for your winning antenna array.

Instead of the usual AC motor drive used in older rotator designs, the G-2800DXA, G-1000DXA and G-800DXA use a variable-voltage DC motor, removing the need for a large starting capacitor with its potential for failure exposed to outside temperature variations. The factory-lubricated rotator unit is housed in melamine resin-coated die-cast aluminum, intended to provide maintenance-free operation under all climatic conditions. A mast alignment gauge on the rotator housing simplifies accurate mechanical alignment during installation. Tower mounted, this model handles over 30 sq. ft. of antenna wind load and over 650 lbs. of vertical mast load. About 130 ft. of control cable is included with the G-2800DXA only. Control console power is 110/120 volts AC. The handsome desktop controller provides 360 degrees radial indication of actual antenna azimuth bearing. You can select rotation time over 360 degrees from 50 to 120 seconds on the G-2800DXA, and preset a desired heading for the rotator, to which it then turns automatically. When a fast rotation speed is selected, special "auto slow-start" and "auto slow-stop" features avoid sharp jolts to the antenna array and tower. Activating the rotator causes it to begin turning at slow, but increasing, speed. As the antenna approaches the desired heading, the rotation automatically slows down, before bringing the antenna to a gentle stop. The operator may select the stop heading, the compass bearing through which the rotator cannot be turned, which is most convenient for their station location and operation, allowing full rotation through north, south or both, if desired. In any case, 90 degrees overlapping rotation allows rotation through the selected stop heading for 450 degrees of total rotation. These rotators are intended for mounting to an accessory shelf inside a support tower (not supplied), at least 1-meter (40 in.) below the top of the tower. Yaesu rotators have a fine reputation within the Amateur Radio community. When installing a new tower, or replacing an old rotator, consider purchasing a Yaesu G-2800DXA Extra Heavy-Duty Rotator System from DX Engineering.

WiMo X-Quad Antennas
WiMo X-Quad Antennas, with separate monoband models for 144-146 MHz or 430-440 MHz, represent a refinement of VHF and UHF cross-polarized Yagis. They are well-known in Europe as "multi-element quads"—an antenna with aluminum elements, not a wire and fiberglass antenna—which offer excellent gain with a relatively short boom length. X-Quads are a great solution due to their short length and lightweight construction, especially for VHF/UHF satellite systems which require rotation in all compass directions and elevations. Two X-Quad Antennas, one for 144-146 MHz and one for 430-440 MHz, may be mounted at opposite ends of an azimuth-elevation rotator cross-boom for high-performance full duplex Satellite operations. For either or both bands, X-Quad Antennas may instead be used in a stationary mount, as pictured, for all-mode terrestrial operations. In either application, multiple X-Quad Antennas may be stacked vertically and horizontally for additional gain and tighter patterns. The WiMo X-Quad special features, developed specifically for Satellite Amateur Radio include: * Switchable Polarization Plane; horizontal/vertical/right hand circular/left hand circular (remote switching requires optional equipment) * High gain compared to other antenna forms due to the "stacking effect" * Short boom length and compact design * Back-end boom or mid-boom centered mounting to the mast is possible The radiator element is a "stacked quad" multi-element beam, for which linear polarization can be compared to a crossed slotted radiator. However, the advantage of the X-Quad is that it can be optimally used for the desired polarization by simply changing the feed. Compared to a typical cross-polarized Yagi, all directors and reflectors are active in the X-Quad, which enables the compact design. As with cross-polarized Yagis, switching is accomplished on the mono-band X-Quad either by a coaxial relay or with a band specific WiMo Remote Polarization Switch (sold separately). If the remote switch is mounted at the antenna, then only one coax cable and a 4-conductor control cable are required, sold separately. If the Switch is used at the station, then two coaxial cables from the antenna to the station are needed. The WiMo X-Quad Antenna can also be permanently set for circular operation by using an optional, band-specific Phase Line. The secondary elements are arranged diagonally in relation to the square-shaped driven element, which corresponds to the voltage distribution on the radiating element, for the most favorable results. In comparison to Yagi antennas, the X-Quad pattern and tuning are affected less by the influence of external fields, making them ideal for installation under a roof, in an attic space. All elements are electrically conductively connected with boom and cable outer sheath, thus eliminating interference from atmospheric noise. Two Type-N female coaxial connectors, one for each polarization, are mounted in a housing that is waterproof. Boom and elements are made of aluminum, all hardware is stainless steel. Construction and design of the antennas are protected by law (DBGM). The antennas are designed for boom-end mounting; however, alternatively the mast clamp can be mounted in the middle of a non-metallic boom. These antennas have a split boom, so their transport length is only 29.53 in. (75cm) for the 2m antenna and 25.59 in. (65cm) for the 70cm X-Quad. For portable operations they can be stowed away comfortably in the trunk of car and their shipping costs are comparatively low.

M2 Antennas HO LOOP Antennas
M2 Antennas HO LOOP Antennas provide easy SSB, CW and Digital communications out to 200 miles or more. These are great VHF and UHF antennas for the new operator just getting started in either mobile or base weak signal operations. HO LOOP Antennas are the right choice for any operator who wants the convenience of omnidirectional coverage, with the correct polarization, without investing in a rotator and support that is required for Yagi antennas. HO LOOPs transmit and receive horizontally polarized signals that are required for weak signal operation, where verticals are not effective. Horizontal polarity permits HO LOOPs to add upwards of 5dB of ground gain that verticals cannot. As with most horizontally polarized antennas, performance improves dramatically with height above ground, especially on VHF and UHF bands. Physically, the HO LOOP Antennas are square, fabricated from two 3/8 in. diameter aluminum tubes to minimize losses. Their sealed feed block provides weather protection with minimum wind drag. The heart of this unique design is the shorted stub matching to a 50 ohm coaxial feedline. They are lightweight and have very low wind area, which makes them ideal for stacking in base or mobile operations. Mounting is via a single 3/8 in. hole that is standard for most mobile hardware, with optional mounting hardware available for base* or mobile installations, as shown. Minimum vehicle mounting height and stacking separation dimensions are displayed in the details for each HO LOOP. Gain figures appear below and in their Instruction Manuals. *NOTE: Mounting of HO-LOOPS on a 1-1/4 to 2 inch mast for base operations requires the optional MSQ-MASTBRKTKIT. Enjoy the thrill of VHF and UHF weak signal operations with M2 Antennas HO LOOP Antennas from DX Engineering! Gain figures for each loop at specific heights above ground for mobile operations. However, loop installations for base operations should be as high above ground as possible, just as though it were a beam (but no rotator required). 50 MHz Gain: Single HO Loop at 11 ft. is 4.2 dBd at 25 deg.; Stack of 2 HO Loops at 40 ft. and 52 ft. is 8.2 dBd at 6 deg. 144 MHz Gain: Single HO Loop at 10 ft. is 4.0 dBd at10 deg.; Stack of 2 HO Loops at 82 in. and 132 in. is 8 dBd at 9 deg. 222 MHz Gain: Single HO Loop at 84 in. is 4.7 dBd at 7 deg.; Stack of 2 HO Loops at 84 in. and 117 in. is 8.2 dBd at 7 deg. 432 MHz Gain: Single HO Loop at 86 in. is 5.0 dBd at 4 deg.; Stack of 2 HO Loops at 84 in. and 100 in. is 8.8 dBd at 4 deg.
