The RF/Microwave Instrumentation division of AR Worldwide has introduced a heavy-duty,non-conductive support and positioner for two of its high-gain,log periodic antennas. The new AP5010 positioner is compatible with antenna models AT2526 and AT5026. While the AT2526 antenna covers the frequency range from 26 – 250 MHz and accepts up to 15 kW input power, the AT5026 frequency coverage is 26 MHz – 5 GHz and accepts up to 5000 W input power. The new antenna positioner is built on casters for easy movement in a shielded room or in open site testing.The design of the AP5010 also allows the test engineer to position the antenna for either vertical or horizontal polarization as well as permitting the antenna to be tilted at 30 degrees.
