The ANT901 is an antenna designed for internal applications, offering a low profile and wide bandwidth to cover both European and North American SDR/ISM bands used by FLARM devices. It is well-suited for applications in the vicinity of cylindrical batteries. Manufactured from stamped metal, it offers low cost and low production tolerances. To avoid vibrations of the systems, the antenna contains a mounting hole for attachment to a PCB with a plastic spacer.
Key specifications include a frequency range of 868 MHz – 930 MHz, an impedance of 50 Ohms, and a return loss of 8 dB min. The antenna has a maximum gain of 1.8 dBi and a maximum horizontal gain of 0.3 dBi, with vertical polarization. It is constructed from Brass C27400 / Electroless Nickel Plating.
