What's this for?

Maybe, but none of the ham antennas in an image search[^] are parabolic.
Quote from here:http://www.hamuniverse.com/ve3sqbprog.html[^] "Parabolic antennas are the most directional of all antennas and have the most gain. Because of their size, they are usually used for UHF and up. They are much easier to built than you think. Any long bar will bend to a parabolic arc when stressed on the end. If you mount 1 X 1 inch wood strips solidly to a center hub, a wire can be strung through loops on the outer ends. When the wire is drawn tight, the ends will curl up forming the dish."

I thought pretty the same: He finished to build an umbrella but a storm has taken away the umbrella material and left behind the deformed umbrella skeleton... :) ;)

A guy at one of the houses I drive by daily has recently erected this thing[^]. I tried Googling what it's for and I'm now considering stopping by one day and just ask. I don't know much about radio communication (other than what I've learned from being part of a WUG[^]), but this antenna looks like it works with very low frequencies, I don't understand why it's pointing straight up though.

Take my advice: DON'T go asking your neighbours about their erection. It'll give them the wrong idea about you (I hope :~)

You mean you want to double the nagging and bitching? Trust me, I do NOT understand the mormons at all! No, take my advice: It's much better to rent! :rolleyes:

I think the term you are seeking is "cobbweb antenna" used for HAM radio sets. http://www.bing.com/images/search?q=cobweb+antenna+build&qs=PA&sk=AS1&FORM=QBIR&pq=cobbweb%20antenna&sc=6-15&sp=-1&qs=n&sk=[^]

It's called a hex-beam. It is basically a set of 2 bent dipoles on each of several HF bands. One of the dipoles is driven and the other is a parasitic element. The wires are held in tension by the bent radial frame and spaced so that the dipole lengths correspond to the necessary wavelengths on each band. Usually they are for the 20, 15 and 10 meter bands, but all sorts of other combinations (i.e. 17 and 12 meters) are possible. The lower frequency bands (i.e. longer wavelengths) aren't practical because the size gets too big. More information: Bing hex beam[^]
