Here it is — the full video on the Sirio Gain-Master!
After a few teaser Shorts, this is the main event: a full look at assembly, installation, and on-air performance.
🛠️ What’s in the video:
00:00 Intro
00:28 Timelapse of assembly
03:12 First test on a temporary mount
06:27 Final install on chimney stack & SWR Testing
This antenna's been getting a lot of interest, so I wanted to put it through its paces properly. The Gain-Master is a 5/8 wave end-fed vertical for 11 metres, and it's a serious performer if you're chasing DX on the CB band.
🔧 Mounted with: Chimney lashing kit Heavy Duty
📡 Radio used for testing: Cobra 148 GTL-DX MKII
📍 Location: Athlone, Ireland
Thanks for watching!
