M6AKV’s Variation of the Rybakov Antenna

The experimental spirit of amateur radio lives on! I argued with someone recently about whether or not your average ham was an innovator, I am convinced that most of us are. We may never make that Earth shattering breakthrough that changes the world but each little thing we do has the potential to inspire someone else’s Earth shattering moment. A couple of ideas lately have fired me off thinking “That is a great idea but how can I do that better?”

I was reading the forums on Junksale when I came across Andy M6AKV’s unusual portable HF antenna solution. Read about it here. Andy has taken a telescopic fishing pole and wound it with sticky back copper tape and used a 9 to 1 balun to produce an interesting variation on the Rybakov 806 Multiband Antenna that is still one of the most popular articles on this blog even though I wrote it in June 2009. Even if this antenna is not as good as Andy would have us believe, it works and proves that the experimental spirit of amateur radio is alive and kicking.
The sticky back copper tape Andy uses is sold as Slug Tape. I wish I had found this years ago. I paid stupid prices for tiny rolls of sticky back copper to repair circuit boards. I could have done hundreds with one roll of this slug tape. I have in the past made a 2m on glass J-pole and quad from aluminium flashing tape, but had trouble connecting the feeder. This stuff solders brilliantly and would be great for stealth antennas on glass, stuck to drain pipes or the boards on the eaves of a house. A coat of paint would make them invisible. Also great in glass fibre boats or cars for making a ground plane or radials or for making protatype circuit boards. The brain is ticking over and I am sure I can no longer live without a few rolls of this stuff in the shack. I just have to try Andy’s design for myself too. I am thinking 10m pole for a loaded 80m vertical. Thanks Andy!
