Diamond Antenna Phasing Harnesses
Diamond Antenna Phasing Harnesses provide 2-port phased power division. They are designed for stacking two 2-meter or two 70-cm beams. When you connect your feed line to the SO-239 (UHF female) center, it then provides two outgoing cables terminated in PL-259 connectors. The power division will then feed two Yagis in phase. Diamond Antenna Phasing Harnesses are manufactured using the highest quality materials and have securely attached weatherproof connectors. If you are installing a two-Yagi array, consider one of these handy Diamond Antenna Phasing Harnesses from DX Engineering.

M2 Antennas Power Dividers
M2 Antennas Power Dividers are non-isolation type dividers that serve as RF combiners and splitters for 50 ohm antennas and feedlines. They are carefully hand-crafted to achieve their design frequency range. M2 Antennas Power Dividers are made with Type N female connectors so they have extremely low loss and constant impedance characteristics. Power Dividers are used in VHF and UHF arrays to impedance match two or four Loop or Yagi antennas that are fed in phase, separated by the proper stacking spacing, and pointed in the same direction. As compared to a single antenna, this technique can yield 3 dB gain for two antennas and nearly 6 dB gain for four antennas, less only the minor losses of the phasing lines and the power divider. Each pair of stacked antennas nearly doubles the effective radiated power of the station. The 6 meter band Power Dividers are made with low loss coaxial cables and high quality connectors. All other M2 Antennas Power Dividers are constructed with aluminum tubing or aluminum blocks and solid metal center conductors to make coaxial lines with air dielectric, so their losses are nearly immeasurable. These two-port and four-port Power Dividers feature aluminum brazed joints, machined end blocks and 'O' ring sealed coaxial connectors of the highest quality. Each M2 Antennas Power Dividers has less than 0.1 dB loss and handles 3 kW of RF power. Two-port dividers are used for a pair of Horizontal Omni Loops or a pair of Yagi antennas with equal length of 50 ohm low loss coaxial cables with Type N connectors. Two-port power dividers are also used in arrays of eight Yagis or multiples, to combine each pair of four antennas that are served by four-port Power Dividers. Available now at DX Engineering, M2 Antennas Power Dividers offer the best method of splitting and combining RF in your stacked VHF and UHF HO Loop or Yagi arrays.

I0JXX Power Dividers
I0JXX Power Dividers serve as RF combiners and splitters for 50 ohm VHF/UHF and EHF antennas and feedlines. They are hand-tuned with advanced test equipment to achieve the specified frequency range. I0JXX Power Dividers are made with Type N and 7-16DIN female common connectors and precision Type N antenna port connectors for extremely low loss and constant impedance. They are constructed with aluminum tubing and solid metal center conductors to make air dielectric coaxial lines with nearly immeasurable insertion loss. Power Dividers are used in VHF and UHF multi-Yagi stacked arrays to impedance match two, three, four, six or eight horizontal Loop or Yagi antennas. Standard low-loss 50 ohm coaxial cable Type N male assemblies, each the exact same length are required from each antenna feedpoint to its respective power divider port. But phased wavelength cables are not required. All Yagis or horizonal loops are fed together in phase, separated by the proper stacking spacing, and pointed in the same direction. As compared to a single antenna, stacked Yagis can yield 3 dB gain for two antennas and practically 6 dB gain for four antennas, with only minor losses deducted for the feedlines, connectors and the power divider. Each pair of stacked antennas nearly doubles the effective radiated power of the station. Available now at DX Engineering, I0JXX Power Dividers offer a superior way of combining and splitting RF in stacked Loop or Yagi arrays.
