Imax-2000?
Anybody have one? I am going to stick it in a tree. There are tuning rings on
it. Anyone ever tune one of these? I am going at it alone when I install it. I am going to use a climbing tree stand, and it will be impossible to tune it when it is hung. If I tune it on the ground, will the SWR be drastically affected if it is a couple feet off the ground, as opposed to when it is about 30 feet up? Vinnie S. |

If I tune it on the ground, will the SWR be drastically affected if it is a couple feet off the ground, as opposed to when it is about 30 feet up? Can't say specifically for the 2000. For a 1/2-wave vertical dipole, the input impedance is highest (around 100 ohms) when the feedpoint is 1/4-wave above the ground (as low as it can go without digging a hole). It is lowest (about 70 ohms) when the feedpoint is 1/2-wave above ground. As you get higher the input impedance levels off to slightly above the average impedance of a horizontal dipole (the latter being about 73 ohms). Turning the antenna horizontally won't work because it will then behave like a horizontal dipole, the input impedance dropping towards zero as you get closer to the ground. IOW, if you tune it on the ground, the SWR -will- change after you get it up the tree -- and that's disregarding any effect the tree will have on it's impedance. ----== Posted via Newsfeeds.Com - Unlimited-Uncensored-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 120,000+ Newsgroups ----= East and West-Coast Server Farms - Total Privacy via Encryption =---- |

We sorta tuned it on the mast with the coax stretched all the way out. Now it was a good match when it was down, it went up just a little when all the way up, nut not enough to worry about. I also ran a separate ground wire down from the mounting brackets. Landshark -- __ o /' ) /' ( , __/' ) .' `; o _.-~~~~' ``---..__ .' ; _.--' b) LANDSHARK ``--...____. .'

to bad, the ENTIRE antenna should be out the tree...
I am not saying this to be funny, but you are not getting out anyway near what you would if it was. |

Umh, maybe I wasn't to clear, sorry. The mast is approx 5' give or take above the top, So most of the antenna is well above the tree and works just fine with an SWR of 1:3:1 Landshark -- Treat people as if they were what they ought to be and you will help them become what they are capable of becoming. |

He's a dying part of this newsgroup, most everyone seems to get along ok, except him & Doug...........pity.......... Landshark -- Is it so frightening to have me at your shoulder? Thunder and lightning couldn't be bolder. I'll write on your tombstone, ``I thank you for dinner.'' This game that we animals play is a winner. |
hey landshark what kind of coax you use i wanna put a a99. in an a tree
also .also what about grounding system thanks.ssb 2238 alabama 73s |

I put mine out the top of a tree, and the antenna had a 1.1 SWR right out of th box. |

I am going to run nearly 300 feet of Bury-Flex. For both the Imax and the HF dipole. Someone here told me to use bury-flex. It was a great idea. Who was it? Vinnie S. |

I love mine and it's wife friendly as she can't see the coax hanging around. It is pretty stiff stuff though, no heliax, but a good idea to work with it when it's warm :) Chad |
