3/5 - Antenne HF Multibande Portable, fabrication d'une embase d'antenne "banane" et contrepoids

Hello, This video is a follow-up to the one in which I showed you how to build a portable multiband HF vertical antenna (SOTA). In this tutorial, I show you how to build a banana plug for this antenna and a set of radials. Then, in the field, I perform a SOTA activation at FL/NO-064 in QRP, CW and SSB, with just 5 W. See below for details of the parts needed to build the banana plug and the set of radials. Link to the tutorial for the first plug:    • 2/5 -Tutoriel sur la fabrication d'une emb...   Enjoy watching and happy crafting! 73 Gaël F4IHG -------------------------------------------------------------------------------------------------------------------------------------------- Chapters: 00:00 Introduction 00:28 Brief Overview of the Base 01:14 Feedback on Counterweight Systems 03:08 Presentation of the Removable Counterweight System 04:23 Can the Antenna with this Configuration Be Used on Other Amateur Radio Bands? 04:50 A little theory 05:25 Details of the parts needed to make the base and the radial sets 08:07 Preparation of the three PVC parts 08:36 The lower cap 15:35 "Exploded view" of the banana socket 15:44 Some advice 17:22 The radial set: assembly and reliability 22:23 Base and radial set completed 23:52 Implementation during SOTA activation 26:16 CW QSOs - 20 m - 5 W 28:26 SSB QSOs - 20 m - 5 W 32:13 CW QSO - 10 m - 5 W 37:26 SSB QSO - 10 m - 5 W 38:24 Conclusion ---------------------------------------------------------------------------------------------------------------------------------------- List of parts needed to make Base: Two 1.5-inch or 1/1/2-inch male PVC pressure plugs. https://www.manomano.fr/p/bouchon-mal...
