Feedback from a customer:

Just wanted to say how well the 70cm Slim Jim is performing here locally. I`m looking forward to the 2m version coming to me soon.. And! As you know I just love the inverted V for 2,4,6m. Anyway! I just purchased an 8M mast from moonraker and I`m going use it portable out in the garden. Hence why I purchased the SlimJim 2m antenna this week! It will surely boom out! and it`s a safer way to purchase the slim jim as it will fit 100% to the mast more than any small vertical will...I think all your antennae are good! Can`t be faulted in design and craftsmanship. Over time I`ll be buying a few more as funds allow! lol MM6ECO"
