Howdy
I have an Antene here and I know it can be used for something. It would be good to be able to pickup other stations (free to air) from around the globe or simply just look for video streams.
What equipment would I need to make something like this useful (besides a tv set).
Many thanks,
Ive attached three pics

Do not mean to be picky but the correct spelling is Antenna (singular). As Robert explained, that antenna is for TV and at those frequencies, the receiving antenna must be almost on the line of sight, no obstructions. Whatever station you can receive you can easily drive to visit in a few hours, no hexotic stuff around the world. MG
Back in the late '70s, I used to pick up very distant FM stations (with much fading, but at times in perfect stereo) for a period of several hours on summer afternoons. I was in southwest Idaho, and the stations I picked up tended to be in Texas and Oklahoma. There is some sort of atmospheric refraction that allows this. When this was going on, I could also pick up distant TV stations from the same areas, as well.
A *tuned* amplifier for the station of interest is best; the bandwidth should be just enough for the signal type but no less. The reason is that any such amplifier is likely to be about as noisy as an FM receiver or a TV receiver - meaning the signal to noise ratio will not be much better, and may be worse.
I was using a simple Radio Shack "S" omnidirectional dipole and a Heathkit AJ-1214 tuner. Nothing exotic. As you might imagine, the FM dial was rather empty in rural Idaho in the late '70s. So I'd just tune around looking for signals that weren't from the three or four "local" (Twin Falls) stations I could normally pick up. When the skip was happening, the dial would be just full of signals.
I was in college at the time, FM and DX-ing wasn't my primary objective; I was just searching for some decent rock'n'roll -- anything but disco. So I'd stop when I found a song I liked, and then I'd stay tuned until the station faded out, played some disco, or identified itself. After a while, I started keeping track of frequencies and callsigns.
Very cool idea, might give it a go. Thanks.
Is there some sort of a 'signal amplifier i could get or just hook it up?
Thanks again
I did FM DXing when i was in the service at Huntsville Alabama; sometimes i had to turn the (outside) FM yaggi vertical (!) and 2 feet away from the quonset hut wall for best reception.

Sounds like Tropospheric Ducting. It happens when there is a thermal inversion (warm air under cold air). The VHF signals tend to follow the border between the cold and warm air masses and hence follows the curvature of the Earth over the horizon.
I have keyed up a 2mtr repeater from >300 miles away using a handy-talky and a rubber duck with full quieting into the machine.
