The UHF tracking station antenna rotator is an SPID BIG RAS/Hr rotator (Figure 7) that has 0. RCA connector. When your dish is pointed low down near the horizon the elevation angle is only a few degrees. The QFH antenna works great for circularly polarized signals like weather satellites, but something like a yagi or log-periodic antenna is better for most sats, because it can be pointed directly at the sat. The G-450C is ideal for turning a VHF system, or a lightweight HF tribander. Only at eHam. My use of azimut stop position is a little bit more tricky. It is likely IMO that there are several other make/model antenna rotators in the market capable of 180 degrees elevation range and >360 degree azimuth range, besides the popular Yaesu G-5500 rotator, as such range requirements would be common for satellite & other sky object tracking. Rotator Controller Using Arduino and PstRotator When I first started my 2M EME experiments elevation and azimuth control of the antenna was done manually, using a "plumb-line" and protractor for elevation and circular protractor for azimuth. The Cornell Dubilier Electronics company sold their rotor division to Telex/Hy-Gain in 1981. When aimed at the horizon, the elevation angle is zero. Remember that one end will. from level one. I now have the main hardware assembled and am in the process of wiring everything together. The control box serves as a power supply for the rotator. Nearly all of the San Diego stations broadcast a digital signal, so naturally I was eager to receive digital signals OTA (over-the-air). com When I began this project four years ago, my dream was to achieve mixed-mode DXCC “eventually. Antenna options 1. Is this driving standard hobby servos with PWM, or is it driving some sort of standard (e. IMPORTANT: Azimuth In order to set the limits for both the Azimuth and the Elevation sections of the rotator, first always start by setting up the azimuth section by pointing the rotator to 0 degrees or true north. Posted in Misc Hacks Tagged 2-axis, antenna, azimuth, elevation, positioner, rotator, satellite tracking, stepper Post navigation ← ESP-Micro Is A Tiny Development Board. Re-alignment may be necessary. Rotators are commonly used in amateur radio and military communications.
