[TowerTalk] BIG array

[K7LXC at aol.com]

Howdy --
 
    I don't know if it's been mentioned before but I  was at the SteppIR 
factory yesterday and saw an engineering drawing and photos  of the K9LTN array. 
It's a 270' rotating tower with an "H" frame on it with 4  over 4 over 3 
element SteppIRs on EACH side of the H. The antennas have azimuth  AND elevation 
rotation. I heard that he was able to bounce HF signals off the  moon ala W0UN. 
It is a truly amazing installation. Apparently they used Rohn 55  and 45 for 
the vertical parts of the H. The vertical parts of the H are 100  feet! It has 
over 21 dBi of freespace gain. 
 
    I went to the website - _www.k9ltn.com/_ (http://www.k9ltn.com/)   - to 
look at the photos and they're poorly edited and don't  show any finished shots 
that I could see. 
 
    I think that this is probably the most expensive  single tower 
installation in the country. Everything except the antennas was  custom designed and 
built and professionally installed. I'd estimate that its  cost was over $100k. 
 
    If anyone has pictures of the finished array,  please let us know where 
they can be viewed. 
 
    You've got to admire someone with that kind of  vision. 
 
Cheers,
