Sounded like a pbs special on antennas

where can I order this atenna? Can we cobine this atenna such like two atenna?

awesome video, I felt like I was watching a professional production.

Thanks for this video .Just looking to buy any cross yagi for the 144-146 ham band and see the cushcraft.I can't fix these two things ,one with the connector thing .I must search ,if i buy first ,to buy the mast clamp ,i see from your video is a lot fragile .Any issues with the swr across all band?
