Thanks to a fast delivery from Black Cat Systems I'm using my Squid to tune my skyloop antenna just in time for pirate listening on long winter nights! The wide variety of impedance options allows me to get the strongest signal for the frequencies I'm interested in. The Squid's heavy-duty construction is great for experimenting, since I don't have to worry about "wearing out" the connectors like I do with other transformers I've purchased in the past. This is a great product and well worth the money.
