I was glad to purchase this third book in the wire antenna series. The majority of us have to make do without beams so having a source of low cost alternatives is very handy. Hoping for book 4 in the future. VE3CGU.
I took a chance and ordered one of these for my GPS. It fits perfectly into the cupholder (has expanding mechanism for snug fit) and is quality-built. It holds the Garmin securely, pivots & swivels well. Couldn't be happier.
