Some tilt over mast projects

As important as (if not more) than the type of antenna you used is its height. More height means longer range on VHF and UHF. On HF you get lower local noise and more reliable DX due to lower radiation angles attainable. Unless you live in a tall apartment building, that probably means some sort of mast.

Especially if you're of the experimental bent, putting up and taking down antennas all the time, a mast that tilts over has a lot to commend it. Not least because you can do your work on or near the ground. That's faster and safer than climbing. Many active amateurs would know or know of someone who died from tower-related falls.

Whare are the pros and cons of tilt-over towers? Tilting can put a lot of stress on the tower's pivot. That's especially if it's supporting heavy beam antennas. In such circumstances some sort of crank-up tower may be better. But if your tower is not too high and if you mainly experiment with wire antennas then a tilt up effort might suffice (and be easier to build).    

Below are some ideas on tilt over towers: 

It hardly goes without saying that a tower is a serious project. Especially if it's long, heavy and erected in a high wind area. A poorly built tower can risk property and even life. So make sure that yours is suitably specified and constructed for your site conditions. Local authority approval may also be required. 

Have you had experiences with tilt-over towers? If so please share them in the comments below.
