I use to make a similar claim that the A/P was a 5/8 wave. I've changed my mind though and now believe it is a very effective vertical 1/2 wave. I made the taller model to see if I could scale it to 22' feet, and see how it worked. I ended up with it near 14' instead of the stock 11' feet. The 22' foot idea did pretty much as you suggested and I was no able to get it to match. I stopped fiddling with it, because I did not get an answer to my email to Tagra. Some folks just don't like questions! My comment about brexit was in jest. Corruption is ubiquitous in our World. Do you hear any local comments about the BT-101?
