other e-field probe antennas; measured IP2 +70 dBm, IP3 +40 dBm. +12 V 1M 100 BFG149 or 2N5583 10M BF862 (or J310?) 100 470n (foil) 22u 100n good ground Works on BFN42-2022 Prevents RF oscillations. Mount does not dissipate about 0.4 watt, so use a suitable resistor. This transistor needs a heatsink as it dissipates about 0.4 watt. Works on BF779-2023. The transistor loses above a few MHz, making it very suitable for a broadband choke. Anstelle einer Kupferfläche oder eines Stabs als Antennenelement verwendet PA3FWM in Twente dicke Drähte,
