32 ─ 08 10 Note on the frequency range 9 kHz to 20 MHz As antenna module R&S HE300HF is designed as a loop antenna, vertical polarization (normal handling position) leads to two receive maxima, one in the direction of the signal AH Systems AH Systems SAS-563B Active Loop Antenna 1 kHz to 30 MHz. Conduct emissions and immunity testing typical for military standards and more. You also have control circuits for switching between various configurations. The highest efficiency design will mean that the large loop is 1/8 to 1/4 wavelength of the desire operating frequency. If the target station is audible at all on the radio - it is a simple matter to put an external loop antenna nearby, and tune it until the weak station becomes strong. Although the Loop Antenna can be powered direct from the +5V DC BiasTee Cheap Instrument Parts & Accessories, Buy Quality Tools Directly from China Suppliers:K 180WLA 0. DX Engineering RF-PRO-1B Active Magnetic Loop Antennas are designed for low-noise reception of signals within the frequency range of 100-kHz to 30-MHz.
