EAntenna HF Rotatable Antennas
EAntenna HF Rotatable Antennas include a comprehensive range of mono-band and multi-band Yagi beams and rotatable Delta Loops and Dipoles. Find the band coverage and performance antenna of your dreams right here. For example, the exciting EAntenna 59+ provides great performance on 20, 17, 15, 12 and 10 meters! Check out the specs on this great line of HF directional antennas. DX Engineering offers EAntenna because their attention to manufacturing detail is excellent! Their Yagi, log periodic, and rotatable dipole antennas are built with high-quality stainless steel hardware and aircraft-grade aluminum. As you look through these selections, be aware that advanced, cutting-edge computer modeling and optimization techniques were used to produce every one of the EAntenna premier HF beam antennas and state-of-the-art VHF and UHF Yagi antennas. Their mechanical designs are very robust in every way, as most are rated for at least 100 mph wind survival. To see additional information about each antenna, click on the "More Details" link on the antenna of interest. Then click the Specifications tab to see all of the physical and electrical characteristics of that antenna. EAntenna products are offered exclusively in North America by DX Engineering. Plus, we can ship these great antennas internationally! When you're making plans for a new antenna at your station, look no further for the outstanding solutions by EAntenna, "The Best Choice for Your Antenna System!" NOTE: Manuals are normally supplied bilingual. If your manual lacks an English section, contact DX Engineering for an English version.

Diex Antennas Multi-Band Trap Shortened Rigid Rotatable Dipoles
Diex Antennas Multi-Band Trap Shortened Rigid Rotatable Dipoles offer high performance multi-band HF operations, and they are an excellent choice where there's not enough space for a full-size dipole or Yagi. Crafted with precision in Brazil using quality materials, these aluminum tubing antennas are designed to withstand tough environments assuring long-lasting, exceptional performance. They are packed partially assembled, saving valuable time and effort. Typically mounted on a rotating mast, these unique multi-band HF antennas provide high-band directionality depending upon installed height above ground. Given the nature of shortened low-band antennas with limited SWR bandwidth, these antennas feature the flexibility of physical adjustment to set the lowest SWR to a specific frequency. DIEX Antennas Multi-Band Trap Shortened Rigid Rotatable Dipoles power handling is 1500W PEP SSB, which is further limited if using an antenna tuner. NOTE: Diex Antennas recommends that a directional HF antenna should be mounted on a tower at a minimum height of 33 to 50 ft. (10 - 15 meters) above ground level and must be installed in the clear, away from power lines, trees, buildings or other towers and antennas.

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

Diex Antennas Single-Band Shortened Rigid Rotatable Dipoles
Diex Antennas Single-Band Shortened Rigid Rotatable Dipoles provide coil-shortened specialized coverage of a single HF band that can complement band coverage of existing antennas. Crafted with precision in Brazil using quality materials, these aluminum tubing antennas are designed to withstand tough environments assuring long-lasting, exceptional performance. They are packed partially assembled, saving valuable time and effort. Typically mounted on a rotatable mast, these unique single-band HF antennas provide high-band directionality depending upon installed height above ground. Given the nature of coil-shortened low-band antennas with limited SWR bandwidth, these antennas feature the flexibility of physical adjustment to set the lowest SWR to a specific frequency. Diex Antennas Single-Band Shortened Rigid Rotatable Dipoles power handling is 300W PEP SSB and 100W maximum for digital modes for the 20, 30 and 60M models, 1000W PEP for 80M and 1500W PEP for 40M, which is further limited if using an antenna tuner. NOTE: Diex Antennas recommends that HF antennas should be mounted on a tower at a minimum height of 33 to 50 ft. (10 - 15 meters) above ground level and must be installed in the clear, away from power lines, trees, buildings or other towers and antennas.
