Why Bigger Antenna Coils Perform Better! The Truth About Coil Diameter
When it comes to shortened HF antennas, coil diameter can make a big difference. A larger coil can provide greater inductance per turn, allow wider spacing between turns, reduce some losses, and potentially improve power handling. In this video, I compare a 2-inch diameter coil to a much smaller 5/8-inch coil to see why bigger coils can offer advantages—and when a smaller, more compact coil might still be the better choice for your antenna.

I recently met author Tom Bridge, whose first novel One Last Chance is being published by Pegasus today (at time of launching this video). As I’m also in the process of writing my own first novel, it seemed far too good an opportunity not to sit down and compare notes.
This turned into a completely unscripted conversation about what actually happens when you write fiction: inventing characters, building believable backstories, fixing plot “logic bombs”, researching real places and history, choosing titles, approaching publishers – and that slightly strange moment when your characters begin to feel like real people.
Tom talks about the process behind One Last Chance, his experience finding a publisher and what happens between finishing a manuscript and seeing an actual book appear. I also talk about my own experience writing a novel – including becoming rather more emotionally involved with my imaginary people than I ever expected!
Neither of us claims to be an expert. We’re simply two first-time authors comparing experiences – and discovering that quite a few of them were remarkably similar.
If you’ve ever had a story rattling around in your head and wondered whether you could actually turn it into a book, you may enjoy this.

What’s it like before the show? A controlled chaos. Cars are driving in. People are setting up their booths. Event organizers are wondering why they do this to themselves year after year. Where did 67 tables disappear to? And most importantly, where’s my media pass lol! I’ve always been the kind of person who’s curious to see what it’s like to go behind the scenes. Since Caitlin and I needed to go pick up our media passes on Friday, I thought I’d bring you along for a quick behind the scenes look at Huntsville Hamfest. Hope you enjoy!
