About the Mobile-Whip PCB

Mobile-Whip is an open source PCB design by skuep, published on GitHub under the CERN-OHL-P-2.0 license. It is a 2-layer board measuring 200 × 22 mm, with 52 components from 33 distinct parts.

Other key parts include the LTC6268IS6, TP4054, LP2985-3.3 and TLV431. By type, the board carries 19 resistors, 11 capacitors, 6 diodes, 4 ICs, 4 inductors and 2 transistors.

It belongs with the power & battery and rf & radio designs in this gallery.

From the project

A Mini-Whip clone capable of lower supply voltages or battery powered

- Operates on a single lithium cell, 5V USB Supply, 4.0V RTL-SDR V4 Bias-Tee or 12V-15V Mini-Whip Bias-Tee - Includes lithium battery charger - Uses a LTC6268 ultra-low input capacitance OPAMP instead of JFET input - Requires only 20mA (instead of roughly 50mA) - (Probably) Has better large signal interferer resiliency (causing intermodulation) so it might perform better indoors - Designed for 0.1MHz to 30MHz, but works reasonably well also for listening on FM Radio (100MHz) and VHF bands (150MHz) - Can be easily mounted on a HT (such as the UV-K5 with HF mod) or mobile scanner and is thus…
