What the ^&*% is this?
At the risk of sounding dumb, can someone clue me into the origin of
this antenna and where it's commonly used: http://cgi.ebay.com/ws/eBayISAPI.dll...sPageName=WDVW Thanks, Steve |
I think it is just one of those vertical whips with a Jfet. All those
elements seem to be shorted together, as if it was just one fat vertical. |

And by the look of the base and the way that the nomenclature is on the tag it looks as though it was built for some type of military application. Good hunting for some info on it. dxAce Michigan USA |

I'm going to have to read up on these antennas now that my curiosity is piqued. I'm wondering what the strengths and weaknesses are of the turnstile design. Off the top of my head, I suspect that this is probably not a great receive-only antenna and is probably intended for hams. But I'll see what I can find about this design on the web. You don't see many of these on ebay. Steve |

Based on a very few web returns for this company via Google, Parisi
Associates appears to be a defense contractor, primarily. At least one webpage showed a price of around $49,500 for one of their antennas. The Burlington address seems to be current, although a specific Waltham address also shows up. The antenna looks like mil surplus; sure looks durable! Bruce Jensen |
I don't think it is a turnstile. The element configuration looks like an
attempt to broadband it by making it larger in diameter. The label says "HF active antenna". Looks military. Probably a military portable unit. wrote in message ups.com...

I thought of that possibility but the thing is only 7 foot long. Making
it a few inches wider at that length would not do much in the way of making it broadband. In article , "CW" wrote: I don't think it is a turnstile.

Looks military. Probably a military portable unit. I've never seen that configuration in an antenna before.. the thing looks most to me like an element from an electric furnace.. (that's only what it looks like.. I can see from the label it's an antenna) |
