Mini Whip AntennaWhat is it? The original PA0RDT Mini Whip is a very simple yet highly effective active receive antenna for the VLF, longwave (LW), medium wave (MW), and shortwave (SW) range. It consists of a small metal plate and a buffer amplifier. How it works: The amplifier features: Very high input impedance implemented using a JFET as a source follower, which senses the voltage between the small metal plate and ground Low output impedance implemented using an NPN transistor as an emitter follower, designed to drive 50 ohm coaxial cable This design allows the antenna to perform exceptionally well even in electrically noisy environments or locations where space is limited. Specifications: Parameter Value Application Radio reception only (not for transmitting) Frequency range 10 kHz 30 MHz (covers VLF, LW, MW, SW) Power DC 5 13 V, 100 mA RF connector SMA Feed line 50 ohm coaxial cable PCB material FR-4 PCB thickness 1.6 mm PCB copper weight 1 oz What makes it special? Extremely compact.
