![]() Hi. I have been thinking of making an antenna support (for center of dipole, support of Jpole, etc) Was thinking of using 3 4x4 pressure treated lumber 12 foot lengths. Put them in cement 4 inces aprt (cement will be approx 4x4x4 feet. Put 3 vertical 4x4 into cement about 2 feet. At top of 4x4, create a pivot point, and add 2 4x4s between the other 3. Add another at the top between the two, overlapping the 3 and 2 and 2 and 1 4x4 by about 2 feet. Using 12 foot 4x4 that would give me about 30 feet. Will this work ? Would it stand without guying ? I plan to make this a tilt over at the top of the lower 3 4x4s, maybe extending the next tier of 2 4x4s with somthing on their bottoms to give more leverage for raising. Am I nuts ? (well.... I already know the anser to that... but will this work ? Thanks & 73 Jow, WB2JQT, Newark Valley, NY |

Thanks & 73 Jow, WB2JQT, Newark Valley, NY IF you find an older ARRL Antenna handbook, they routinely showed the construction of a 30 to 40 foot center support for an inverted "V" using 2x4 dimensional lumber, and base and guy wires. w9gb |

4x4's?
Man, if you guy that thing, you could probably put a tribander on it ! :^] jw K9RZZ |

Guy supportsa get in the way of stuff like moving the lawn, and I'd have to situate the mast in a different location than I would want. Thanks for the ideas. 73 joe WB2JQT |

If you wanted to get fancy you could maybe use this technique:

That's the way I designed my present supports. -- 73, Cecil http://www.qsl.net/w5dxp -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =----- |
