As it's Marconi, would this not be an early antenna or something similar ?
-
I shudda thought of that ..... because it sure didn't look like a lightning rod to me.
Probably off of a ship.
-
It's the morse code antenna from the Titanic ;D

Hi I think is a Lightning Rod All the tips come out to thread to change them. It has the form of a lightning rod
-
Ipcress you really do have a lead on that! LOL

Sure looks like a lightening rod to me also.
-
Most lightning rods i've seen are symmetrical, with the the smaller rods pointing up.
This is asymmetrical, or appears to be in the image, and the smaller rods are on one side.
Does it definitely say Marconi ? Doesn't resemble an i in the image.

Found one similarly made !! On the home page above it had some pics about someone named Marconi but didn`t say what he did !!
-
by-the-way, meant to put that GARANTITO is "guaranteed" in Italian.
After doing some sleuthing, came across this about our fellow Marconi http://en.wikipedia.org/wiki/Guglielmo_Marconi (http://en.wikipedia.org/wiki/Guglielmo_Marconi)
After reading that I searched the coherer receiver (radio) that he worked on and look at the antenna in this article
http://en.wikipedia.org/wiki/Receiver_%28radio%29 (http://en.wikipedia.org/wiki/Receiver_%28radio%29) The several reaching/radiating pieces sounds like it has to do with his wireless signaling system in 1904 (used on Ships, etc.)
Interesting to know he was the predecessor to RCA!
Maybe this place will have someone that can help you figure out which invention of his this was!

That's the same guy that was on the nautilus link !! Couldn`t remember his name !! Did not say who made the lightening rod in the link but it is asymmetrical too !! Odd !!
-
Now folks I guarantee ya that you don’t need to have five (5) metallic projections on a lightning rod …… just to insure that iffen the bolt of lightning misses the center post it will surely hit one of the other four (4) laterally protruding posts.
But, if you assume it was a “catch-all” lightning rod …… then it’s a bad design because those four (4) laterally protruding posts should have been evenly spaced around the center post and not just on one side of it.
Me thinks it’s a directional antenna that can be rotated toward the source of the incoming radio frequency. Which is absolutely necessary if mounted on a ship/boat.
-
My thoughts, too, Cogar.
It wasn't a flippant guess about the morse code antenna, KC. Just flippant about the Titanic ;D
Sold many Marconi items before and know the history well.

The lightning rod in the Nautilus link is symmetrical : one large rod, four smaller ones of equidistant length spaced evenly apart. That's symmetrical.
The item Micaela has posted appears to be asymmetrical.
-
Micaela, are there pieces missing off one side? I can't enlarge the picture but it appears there are "places" on the opposite side that don't have pieces sticking out.
-
In Michaela`s bottom pic there are 2 that look evenly spaced left and right, the top and bottom look to also be the same but all the rods are to one side rather than spaced around the circumference of the globe !! Or at least that's the way it looks in that pic !! Can`t see the top pic yet !!

Good work Cogar!!!! I had no clue what it was.
-
Yep Mart, and in that bottom picture can't tell if those are bolts or are places where other projections went at one time! Any ideas?
-
Micaela didn't reply to the last item i helped them with but they should contact the Marconi museum.
Whatever this is, there will plenty of people interested in buying it. Could be worth a couple of thousand.
-
A true lightning rod has to have a means of affixing it to a solid base as well as well as a means of connecting a copper “ground” wire to it otherwise it would serve no purpose other than for intentionally attracting a lightning strike. Like a golfer holding his #3 iron straight up in the air during a thunder storm.
Now I’m pretty sure that if Micaela carefully measures the length of those 5 projections they will all be different in length. Like the picture of this police car with eight [8] different antennas affixed to it.

Fixed your photo for you cogar. Wasn't showing up! :)

See if this one works !!

Ooops,, No it says "access forbidden" !!

Hi, The item is simetrical. But lost some tips. the tips are to thread to be able to change them. For this you see not simetrical. But the item is simetrical. I think lost or some tips were reached by a ray and for that reason they are not.
Regards

micaela you really should try that link to the marconi museum to see if they can help you out! Let us know! :)
