QV seller of various RTL SDR related goods including the LNA4. ALL has just made a post detailing a build of a high performance super simple NOAAMeteor M2 weather satellite antenna. Most antenna designs for polar orbiting weather spacecraft are based on circularly polarized turnstile or QFH designs. However, Adams antenna is based on a very simple linearly polarized dipole, which makes construction almost trivial. The idea is that by arranging a dipole into a horizontal V shape, the radiation pattern will be directed skywards in a figure 0 zero pattern. This will be optimal for satellites travelling in front, above and behind the antenna. Since polar orbiting satellites always travel North to South or vice versa, we can take advantage of this fact simply by orienting the antenna NorthSouth. There is also another advantage to Adams design. Since the antenna is horizontally polarized, all vertically polarized terrestrial signals will be reduced by 2. B. Most terrestrial signals are broadcast in vertical polarization, so this can help significantly reduce interference and overloading on your RTL SDR. Overloading is a big problem for many trying to receive weather satellites as they transmit at 1. MHz, which is close to the very powerful FM broadcast band, air band, pagers and business radio. In contrast a circularly polarized antenna like a QFH or turnstile only reduces vertically polarized terrestrial signals by 3 d. B. As the satellites broadcast in circular polarization there will be a 3 d. B loss in Adams design from using a linear polarized antenna. But this can be considered as almost negligible. Adam also argues that the home construction of a QFH can never be perfect, so there will always be at least a 1d. B loss from inaccurate construction of these antennas anyway. The final advantage to Adams design is that construction is extremely simple. Just connect one element to the center coax conductor, and the other to the shield, and spread apart by 1. Adam 9. A4. QVs V Dipole for 1. MHz Weather Satellites. Adam has tested the antenna and has gotten excellent results. If you want more information about the antenna design, Adam has also uploaded a pdf with a more indepth description of the design and his thoughts.
