Solid and convenient

These are solid masts, yet light enough for a single person to install, secure, and erect with antennas.

Good Product

Quality product, reasonable price, good materials. Also, be aware that this is a large item and requires competent handling and skills to install. Be careful when handling it as the mast sections slide easily. Don't be in a hurry to put it up. Think through the installation process before getting started.

Its great

I had a CM 15 ft mast and had no issues with it. When I needed a mast for a mature radio, I did some research on telascopic masts. It was a no brained. I purchased a 40 ft telascopic mast from Channel Master. I put a IMAX 2000 antenna on it with a ground plan. I needed an extra person to give me a hand hoisting it up. It took some effort, four hrs and I was securing the last guy wire. 100% satisfied.

I am completely satisfied with this purchase. Would recommend it to anyone. Why pay more. Happy I found this site before being robbed elsewhere.
