Remember that giant antenna a group of Finnish hams put up? Yeah, the 3 element 160m beam. Looks like they had a bad storm up there and the antenna collapsed.

That has GOT to be an expensive repair.

More details to come...

What a shame.  A lot of hard work, not to mention the cost, will be required to put that monster back up.

Wow, that is a shame. I remember when I got back into the hobby a few years ago and first came across the picture and read the details on the OH8X 160M monster antenna. I think the drool marks are still on the table Smiley The main thing is hopefully nobody was working on the antenna at the time and everyone is OK.

I'm sorry to hear that. I was looking forward to working them in this weekend's 160m contest. I have a new antenna on 160m Grin. Hopefully they just lost one element and the antenna still works FB on two good elements Smiley

Think the tower and all has fallen so that would mean the 80m 5el is gone too,

I read they were planning on replacing it anyway don't think it was as good as they planned,

I may have misread my info before any legal team from OH8X come looking for me,

Although I've worked OH8X on a couple of other bands, I've never had the pleasure of even hearing them on 160.  I have worked other OH's on 160m.

If I remember correctly, they're too far north (magnetic field etc.).   It would be better to be further south.  Can't use the full benefits of an antenna that size.

From my understanding their 160m 4-square out performed the yagi most of the time, and antenna was more an experiment in engineering than anything else - that it stayed up as long as it did in the arctic is a testament to its construction. 

80m yagis seem popular in California and Northern Europe.  It seems as though vertically polarized arrays out perform them most of the time, and are much easier to maintain.  K3LR's mega-station's primary 80m system is a pair of 4-squares that can be fed together in phase.

Michael G7VJR wrote an interesting piece on the antenna after visiting it.   About half way down.

There is a saying that if you put up an antenna, and it does not break, then it is not big enough.

Bummer. I used to show that to non-hams to try to convince them what I do is different from CB.  Grin

Eric, based upon your QRZ page...5 minutes with anyone who will listen will quickly call out the difference between you and a CB operator (not meaning to knock CB radio, just saying your achievements and homebuilt gear speak volumes about who you are).

Mark, your comments piqued my interested so I read KF7CSO's bio and I like it very much. He has certainly accomplished a lot in a few years. I like the short updates he included as he progressed (BTW, Eric, you are not alone in your dislike of the digital modes). Not many building 6AQ5 40 meter cw transmitters anymore or winding their own coils! The picture of Nevada in the upper right hand corner is worth the visit alone.

KF7CSO: Very good show OM and Mark is correct that nobody will mistake you for a CBer.
