What type of antenna is this?

What type of antenna is this?

RE: What type of antenna is this?

It's a commercial TV antenna.

They don't work very well, and there have been reports that the built-in preamplifier can occasionally oscillate causing interference.

VE1BLL,
Is that uhf only, seems a bit small to pick up channel 2.

RE: What type of antenna is this?

They're advertised to cover all channels. Inside it is typcally a folded dipole curved into a circle. And a built-in preamplifer. The bigger versions often have a built-in rotator system.

They work about as badly as you might expect. They don't contain any magic.

RE: What type of antenna is this?

Seems marketing can do magic to bring in money. People think "they wouldn't sell it if it didn't work".

About 3 years ago in a catalog I saw a crystal that you put in a microwave oven to take out the bad microwaves so  your food tastes better. I wrote to the guy and told him that's ridiculous and he said he just sells the stuff. He didn't say they sold like hotcakes though.

Thanks for the info, I'll avoid it (I don't have a TV anyhow)

They're sold as omnidirectional especially useful for caravans.  A bit better than a bent coat hanger.

(OP)
Thanks guys for all the info, thats a picture of my neighbhor's house. The house was sold recently and the new owner asked me if i knew anything about the antenna. Now i can tell him that he can take that eyesore off without any worries.

Thank you all!

RE: What type of antenna is this?

"...omnidirectional..."

As I mentioned, the larger editions have a built-in rotator. But they probably receive equally poorly in all directions.

RE: What type of antenna is this?

I haven't seen that one, only the small ones that would be no bigger than about .4m dia.  A few years ago someone was demonstrating a yagi embedded in in Hi-K ceramic that allowed it to be shrunk by a significant amount.  I haven't seen one on the market - must have been too expensive.
