In this video, I share my DIY modifications to make the Mobile-Whip active antenna even more compact, lightweight, and truly portable for field trips with the Malahit DSP2 SDR receiver.
The Malahit-DSP2 is an incredible wideband portable receiver (10 kHz – 2 GHz), but fitting the active antenna setup into the original travel pouch required some tweaks. Watch step-by-step how I modified the antenna body, reduced the bulk, and optimized the battery setup for portable Ham Radio and SWL listening.
📌 In this video:
- Overview of the Malahit DSP2 and Mobile-Whip active antenna setup
- The main issues with portability and pouch fitting
- Step-by-step DIY antenna modifications & battery optimization
- Field testing and reception results on HF/SSB
